Setting up a smartphone with two SIM cards.
How to set up a smartphone with two SIM cards.
Having a phone or smartphone with support for two SIM cards is very convenient and
profitable. Many mobile operators provide communication services between
subscribers of your network for free. What if your friends have different SIM cards?
operators, then you can talk to them for free using different SIM cards.
But in order to use this, your smartphone needs to have support for two SIM cards.
Don't forget that on the vast majority of smartphones the device can be active at the same time.
only one SIM card. That is, both SIM cards work for reception. But as soon as you start a conversation with
subscriber on one SIM card, a subscriber who wants to call you on number two,
will not be able to do this. He will be informed that you are busy or out of the service area. After graduation
conversation, you will see that you have a missed call, and you can call this person back.
To configure the operation of SIM cards, you need to do the following:
Insert two SIM cards into the smartphone, and in place of 1 SIM card you need to put your “main” SIM card (with the Internet, on which you will register Viber and WatsApp), although on some (newer) smartphones this is not necessary,
- turn on the smartphone,
- open “settings” by clicking the settings icon (or gear, or slider)
- open the “SIM cards” or “SIM card manager” section
- turn on the slides for SIM card No. 1 and SIM card No. 2 (move them so that they turn green)
- click on SIM card 1
In the table that appears, you can change the name of the SIM card (delete the old name and write a new one in the same way as you wrote the SMS), you can change the color of the contacts for this SIM card, write down the number of this SIM card, if you have such functions in your phone (I have such functions No)
- after making the changes, be sure to click the OK button at the bottom of the sign to save the changes.
- click on SIM card 2 and do the same procedure as with SIM card 1.
- click "Mobile data"
- select the SIM card with which we plan to use the Internet (on which tariff plan the Internet is cheaper, we choose that one), click on it (its name will be displayed)
- “Phone calls” and “SMS” click in the same way and select the “always ask” option both there and there.
- press the "BACK" button
- click on the item "Data transfer" ("mobile data")
- click on the inscription sim 1 at the top
- turn on the mobile data slider (move it)
- click on the inscription SIM 2 at the top
- turn off the mobile data slider (move it)
- if you take the Internet from SIM card 2, do the opposite
-on some smartphone models, mobile data can only be connected for both SIM cards at once, so we do that (enable it for both)
- press the "BACK" button
- click "MORE"
- click on "mobile networks"
- for the first SIM card (and then for the second, as we did before) select “network type”
- here I advise you to choose GSM, WCDMA, auto , for the SIM card from which we get the Internet, and only GSM for the second SIM card (because 3G or WCDMA can only be enabled for one SIM card, and on some smartphones, for example on Samsung, 3G can only be enabled for the first SIM card)
- on the desktop, look for and click the “Contacts” icon
- press the "all" button
- Click on the settings button (magic three dots)
- select "contact filter"
-if you don’t have such a function here, don’t despair, it can be hidden, for example here, like
in the figure below and your inscription will mean the place from where you are currently showing
contacts. It can be “phone memory”, SIM card No. 1, etc. Click on the inscription and it will open
window where the contact filter you are looking for will be.
-for example on Lenovo smartphone you need to press the menu button (to the left of the home button at the bottom of the screen)
and in the sign that appears, select “contact settings” and “contact filter”
- select which contacts will be displayed in your phone book, SIM 1, SIM 2, phone or others.
-if you don’t know (don’t remember) where you have which contacts are recorded, select “show all” or “all contacts”
I recommend choosing the “customize” option (or your own)
Here I advise you to select the contacts of your phone and both of your SIM cards (don’t forget to click “OK” each time to save the settings.
-and if you have google account and the contacts are stored on its server, then select google contacts, how to do this look " "
- press the main screen button
If everything is done correctly, when you click on the “Contacts” icon in the “all” item, all your contacts should be displayed.
Now, to call someone, you need to click on the desired contact,
click on the number of one of the subscriber’s phone numbers (if there are several),
select the SIM card with which you will call him,
press the "call" icon
after this the connection with the subscriber will be started.
To end the conversation, click on the red button at the bottom of your screen.

What are the advantages and disadvantages of dual SIM phones?
The first phones with two SIM cards appeared five years ago, in 2006. At the origins of this trend in our country was a company, and almost in parallel with it, the company began working in this direction. Today, models with support for two SIM cards are available not only from these manufacturers, but also from Fly, LG, and Gygabyte. The demand for such phones is steadily growing, and, as a result, the supply is also increasing. Let's look at the main differences between phones with two SIM cards, as well as their main advantages and disadvantages, knowledge of which will help you make right choice between several models.
One or two radio modules: what's the difference?
Dual SIM phones are very different from each other. And it’s not about the form factor, screen parameters or electronic “stuffing” - the main difference lies in the number of radio modules. A regular phone with one SIM card has only one radio module. A phone with two SIM cards can have one or two radio modules. In practice it works like this. In a phone with one radio module, both cellular operators can work simultaneously only in standby mode. When the phone receives an incoming call, the second number becomes temporarily unavailable (as if the SIM card were in a switched off phone). The same applies to accessing the Internet - while one operator sends and receives GPRS traffic, the second is in an inactive state. But keep in mind that some budget phones don't even have this option, and you end up having to constantly reboot the phone to select a different active SIM card. They have only one advantage - there is no need to open the case and rearrange the cards from place to place. Fortunately, such phones are becoming increasingly rare on sale, and new models with such a “feature” no longer appear.
In a phone with two radio modules, both operators are available at any time. If an incoming call arrives on one of the SIM cards, the second call will be on hold, and you can always quickly switch to it and continue communicating with another interlocutor.
Dual SIM Philips phones, Fly, Samsung
The problem of switching between two different operators each manufacturer mobile phones solves differently. Some models have a switch button on the side, other models have two buttons for calling a subscriber at once, and others have it on the program level(the selection function is activated only where it makes sense to select - in the phone book or in the browser). By the way, all phones with two SIM cards have two IMEIs; this fact should be taken into account when searching for a stolen phone and when registering the phone.
Advantages of phones with two SIM cards
The first advantage of mobile phones with two SIM cards is precisely that they really allow you to save on communications. Mobile operator tariffs often allow you to communicate within the network for a purely nominal fee, but calls to other operators are usually too expensive. Therefore, buying such a phone and two SIM cards will help you stay connected on two networks at the same time and not spend too much money on calls. The second saving option is to use one operator for call service, and a second one for surfing the Internet.
The second advantage is that by buying one phone, you get rid of the need to carry two devices with you at the same time or periodically rearrange two different SIM cards on one mobile phone. In the first case, this will save space in your pockets and bags, and your hands will be freer if you don’t have to hold two phones at the same time. In the second case, you will simply save your nervous system - if you need to urgently make a call from the second SIM card or not miss an important call within the network of the second operator, every second can be decisive.
You can often save money by buying a phone with two SIM cards. IN Lately more and more are appearing in this segment budget models. Particular credit here goes to the manufacturer Fly, whose assortment includes many devices in the budget and mid-price categories. It is noteworthy that it was this company that almost completely abandoned the production of regular phones with one SIM card, but the variety of models with two SIM cards is impressive - the assortment includes modern touchphones, budget all-in-ones, universal sliders and clamshells, some models are decorated with rhinestones and are oriented exclusively to a female audience of buyers. And here main competitor- Samsung is in no hurry to bring it to market budget solutions with two SIM cards, so its models are traditionally more expensive. Among the most famous devices from this manufacturer are the D880 Duos, C5212 Duos, C6112 Duos and B7722 Duos. The first model in this list - the D880 Duos - really became the first dual-SIM device from this manufacturer and the first phone in this segment that gained popularity in Russia (although Fly officially took the lead, this event did not receive due publicity).
The famous Samsung D880 Duos
When talking about inexpensive mobile phones with dual SIM cards, we cannot ignore Chinese-made phones. In particular, the brand. At a very affordable price, Anycool phones have almost everything you should have modern phone: touch screen, Wi-Fi module, map support microSD memory, module for viewing mobile television and much more. Therefore, if you are not confused by the origin of the phone and the little-known brand, you may well become the owner of such a phone. By the way, among the “Chinese” you can even find phones with three SIM cards!
An example of a Chinese-made dual-SIM phone Anycool T808
Disadvantages of dual SIM phones
If you own a phone with two SIM cards running at the same time, you will probably notice how quickly the battery will drain. Moreover, the charge reduction will occur faster even when the phone is in standby mode. The fact is that both mobile operators through certain moments time, they exchange signals with base stations, and this precisely requires some activity, which leads to battery depletion. If you regularly use your mobile phone to make calls, send messages, surf the Internet or watch multimedia, you will have to recharge it even more often.
Most dual-SIM phones will need to be recharged every one or two days, even if they don't have a huge battery life. touch screen(as you know, the display is one of the most resource-intensive parts of the phone).
There are exceptions to this rule - the manufacturer Philips, famous for its Xenium line of devices, also produces phones with two SIM cards. The peculiarity of this line is that all models in it are capable of working for a very long time without recharging. In practice, Xenium phones with two SIM cards under moderate load can last 4-5 days before the next recharge. Models X806, X503 and 9@9w have this feature.
If you use the services of two operators and have two phones at once, then if one of them is stolen, lost or broken, the second one will always remain with you, as will one of the SIM cards. If you have a phone with two SIM cards, you will lose everything at once - the phone, two SIM cards, and the ability to quickly make an important call. Therefore, some still prefer two separate phones rather than one.
The next point cannot be considered an obvious drawback, but it can still bring some inconvenience. The fact is that among devices with two SIM cards there is a very small selection of smartphones. The only exceptions are the manufacturers Acer (model DX900), (model) and Philips (model V816). That is, if you want to have a phone with two SIM cards and at the same time use multitasking mode, an advanced organizer, functional mail client, view and edit documents created in MS Office, your choice will be very, very limited. By the way, Nokia fans can also be upset - this manufacturer has never previously released models with support for two SIM cards for sale in Europe, although information about the release recently appeared budget phone with two SIM cards, which will be sold here too.
Example of a dual-SIM smartphone
What does the future hold for dual SIM phones?
If we take into account today's development trends in this segment, we can make a few simple assumptions. For example, budget and mid-priced phones will continue to appear on sale. In parallel, we should expect the emergence of smartphones with two SIM cards running Android OS and the expansion of the model range of smartphones in particular. Therefore, if you want more options when choosing a dual-SIM smartphone, you may want to wait for new devices to appear in this segment. In general, the fashion for dual-SIM phones is not going away, at least this is evidenced by the fact that many famous manufacturers are trying to introduce at least one or two such devices into their range of models. Therefore, if you are trying to save on mobile communications or mobile Internet, but are tired of using two different phones or rearranging SIM cards, dual SIM phones will be the best choice for you.
You can’t force someone with no experience communicating with modern technology into the settings section of your smartphone. This approach sometimes leads to confusion, and a gadget that has not been told exactly how to behave begins to live its own life. One striking example is a smartphone with two SIM cards, which people use together to optimize spending on mobile communications. However, such optimization will be of no use if the smartphone does not receive precise instructions from you when and which SIM card to use.
It’s easier with calls and SMS: most smartphones, when you try to call or send a message, ask each time which SIM card number you need to use. The main thing here is to initially know your SIM cards in person and understand which one is the first and which is the second. As a last resort, this point can be clarified in the settings, in the “SIM Card Management” section.
There you can see which operator serves each card.
If the operator is the same, as in our example, you will have to deal with the numbers. Each operator has its own options for clarifying the number corresponding to the SIM card. In MTS you can call from the desired SIM card to short number 0887: the number will be dictated by the answering machine. This call is free.
Let's go online
On your smartphone with two SIM cards, the situation with mobile Internet is more complicated. If you open the application for social network or the browser, your gadget, without asking you anything, simply connects to the Internet using the specified settings, and perhaps through the wrong SIM card. This is why it is important to be able to change settings.
In the screenshot above, find the “Default data transfer” option. You see that the data transfer (i.e. Mobile Internet) is configured for the second SIM card. At the very top of the screenshot you can see that for each of the SIM cards the following types are described: cellular networks, which can be used. In particular, the first SIM card has access to any network, including the fastest, 4G. The second card is only “capable” of 2G, and therefore is only suitable for calls and extremely slow mobile Internet. Obviously, you should change the settings by switching the Internet to the first SIM card, like this:
We climb under the hood
Eat important nuance: the availability of modern cellular networks often depends not on the SIM card and the complete coverage of operator networks, but on how you placed the SIM cards in your gadget. The fact is that in many phone models, only one of the two SIM card slots can provide connection to 3G and 4G networks. The second slot has limited functionality and is only compatible with 2G and calls. We took our screenshots from just such a smartphone.
If you mix up the slots and the SIM card for the mobile Internet is in the wrong place, you will have to swap the cards. In some smartphone models, during this procedure you will encounter another problem: sometimes the slots are designed for SIM cards different sizes. To resolve this problem, the SIM card can be replaced while maintaining the number at the operator’s office, telling its employee what size card you need. As a rule, the SIM card replacement procedure will not cost you anything.
There are also adapters that allow you to install small cards in larger slots, and large cards can be cut using a special device. You can almost always find it in a store that sells cell phones. Cutting a SIM card is usually a paid service.
As you can see, a dual-SIM smartphone gives you great convenience, but it can also have pitfalls. Now you know how to get around them.

You will learn about the latest events and news from manufacturing companies mobile technology, you will witness new ideas that are the result of their fierce competition, find out which models will be in demand in the near future, what they will look like and how much more functional they will become.
Frequently asked question: does my smartphone work on all foreign networks?
The site is constantly expanding to provide a broad overview of devices on the market. A few years ago this question should have been asked with some concern. As of yesterday, this application no longer works and a replacement must be completed. If you search on the Internet, you come across numerous alternatives that have one thing in common: the smartphone must be rooted! Android roots are dangerous and should only be done by people who know what they are doing there. Otherwise, you quickly turn your smartphone into an expensive paperweight.

Dual SIM phones are increasingly appearing in the range of models from the world's leading manufacturers. And even though the absolute majority in this category belongs to Chinese masters, among those who have proven themselves on the market you can also find worthy representatives from and. Despite the relatively high popularity, phones with support for two SIM cards still raise a number of questions and discussions about the feasibility of this phenomenon. In this article we will try to answer all the expected questions, and you will draw a conclusion for yourself whether or not it is worth buying such a mobile device.
Nowadays, a smartphone is practically a computer that fits in the palm of your hand. In it we can use applications to listen to music, take photographs or even play video games. However, messaging apps are still the most important ones, requiring all those internet connections.
Bring your phone to someone without losing our line
If you plan to use your phone with two lines, there are quite a few options, such as the ability to clone the app to not only have two lines on one phone, but also two accounts. A friend or family member has had their phone turned off with no battery and is waiting for an important call. There is no charger and someone does not have a power bank. Nobody wants to leave their phone on hold. Any solution?
Who needs it? How often do you see people who use several mobile phones for communication (for example, two or three). We will not be surprised if the answer turns out to be positive - the number of telephones has long exceeded the number of the active population. And they all have very similar reasons not to use the tariff of one operator, but to distribute phone functions between different cellular operators and SIM cards, respectively.So, some are attracted by cheap tariffs. Almost always, calls within the network of one operator cost almost nothing or are estimated at a purely symbolic amount, so buying two SIM cards and talking to different people using two tariffs is much cheaper. Sometimes it happens that one tariff is ideal for calls, and the second is used for surfing the Internet. The third category of people, usually sociable people, often from management, have one phone with a personal number, and the second with a work (corporate) number. Moreover, the first one is known by a strictly limited number of people, and the second one can be turned off at any time - for example, after hours, at night, on a holiday, etc.In general, the appearance of phones with support for two SIM cards was an expected event for many, because there is no need to carry two mobile devices with you at once. These sentiments were immediately picked up by only a few manufacturers, but they can now rightly be considered trendsetters in the production of mobile phones with two SIM cards. How it works? When buying a phone with support for two SIM cards, you should keep in mind that this device will have two radio modules and two IMEY numbers, as if you still have two separate phones.Each manufacturer decides the software aspect of working with different SIM cards in its own way. For example, some devices have buttons on the side ends for switching between active cards. During an incoming call, information about two operators is usually displayed on the screen, and the user himself chooses which tariff to accept the call from. It is also possible to implement two mechanical keys at once for receiving calls, although most often this is just one classic button with a green handset. In the case of a touch screen, there is no problem at all - two cards will be displayed on the screen, and to receive a call, you just need to click on one of them.Device settings also often affect both SIM cards - for example, you can configure operating profiles and sound volume for each individual operator. If you often access the Internet with only one SIM card, it is advisable to configure the WAP profile only for it, so that there is no unnecessary confusion.Pros and cons of phones with two SIM cards.Like any other phenomenon, phones with support for two SIM cards have both positive and negative sides. Let's try to list them all. So let's start with the good stuff. 1. Using dual-SIM phones allows you to save on communication and other services of a cellular operator, since it is easier to choose two different tariff plans than one universal one.2. There is no need to carry two devices with you at once - it is heavy, bulky and inconvenient.3. If one device breaks down, you can always choose one card out of two and continue to communicate using it for at least some time while it is being repaired. Naturally, it was not without its drawbacks.. 1. A phone with two SIM cards discharges much faster - information is exchanged with the base station not by one SIM card, but by two at once, so the battery life of the device is seriously reduced.2. Lost or stolen phone - and you are left without two of your numbers at once; with two phones, at least one will remain (although some may lose both devices at once).3. A small selection of models that support two SIM cards at the same time and a complete absence of budget models in this segment (with the exception of Chinese-made phones).There were equal numbers of pros and cons, but let everyone determine their weight and significance for themselves personally.What to choose fromToday the choice is not so great, but almost everyone can find something to their liking. The majority of models are produced by three manufacturers - Samsung, Fly, etc. Now let’s look at the most of them published.For example, a typical example of an inexpensive mobile phone that supports two SIM cards at the same time. It is made in a candy bar form factor, compact and lightweight, with a two-inch diagonal screen. The device allows you to use its advantage both when calling contacts and when sending messages, and the time battery life with an average load it is about two days.Another model from the same manufacturer is more suitable for a business person. This is a typical business class in a slider form factor, more expensive than the previous model and made of higher quality materials (for example, there are also metal parts, the screen has a larger size).Much more interesting are the models from the Korean manufacturer Samsung, which produces them under the DuoS brand. Quite a lot of such devices have already appeared in different price categories. Here we can mention the D880 DuoS, the D780 DuoS, etc. The first is made in a candy bar form factor, the second is a slider, and the third is a modern device with touch controls and TouchWiz interface. The last device is also the most expensive of the three listed, since in addition to a large touch screen and a convenient software shell, it also offers a five-megapixel camera module in its arsenal of functions.Other manufacturers are also gradually bringing to market niche models with support for two cellular cards - for example, u. Knowing about the distinctive feature of the devices in this line - the amazingly long battery life, this device could be called almost ideal, if not for one annoying characteristic - in fact, both SIM cards here cannot work simultaneously, a reboot is required to switch between them apparatus. It is clear that the manufacturer did not bring this device to perfection, but left it in an unfinished state. Externally, this model also looks nice: compact size, light weight, scratch-resistant coating and battery life.This is not the first example of such an implementation of two SIM cards - the pioneer among dual-SIM devices, Benefon, released the Twin model 10 years ago, which also required a reboot to switch.But the joint venture has brought to the market many models that have something to boast about besides two SIM cards. For example, this is a large high-quality screen, the presence modern communications and most importantly - support for digital television!. China will help us Chinese manufacturers are the most productive in the world. A joke is a joke, but there is a lot of truth in it. Indeed, a very large assortment and quantity of goods, including electronics, are produced in the Middle Kingdom. Chinese craftsmen are savvy, have cheap labor at their fingertips and plenty of enthusiasm. In addition, goods from China are cheaper than their European or American counterparts, so they can easily compete with them, if not in quality, then at least in pricing. And many well-known concerns for the production of mobile devices are transferring their production capacity precisely in this country, so not everything that is “proudly” made in China is called a Chinese counterfeit.While the majority of our compatriots continue to be prejudiced against Chinese-made products, local manufacturers are making serious steps forward and creating such interesting and functional models that not paying attention to them would be akin to a crime. It has also become a “good tradition” to create replica models of the most expensive and functional devices -,. Often they are also equipped with slots for simultaneous operation of two SIM cards.What about people who want to have a phone with two SIM cards, but none of the commercially available models fits it? This situation can be resolved, but with some risks for the device itself. The fact is that it is technically possible to combine two SIM cards in the body of one device using a special adapter. True, this is fraught with some negative consequences: the cards will have to be cut (the total volume of the occupied structure will be slightly more than one standard SIM card), inside the case you will need to make room for this structure (usually part of the plastic is cut out), and most importantly - your mobile phone will This will never be accepted for warranty service at an official service center. There are also a number of small nuances - the inside of the phone will be sloppy, there is a possibility of damaging something during the installation of this adapter (for example, when cutting a SIM card, you will touch its electronic part, capturing more plastic than necessary). It is also inconvenient to use such a device because the software supports two cards. mobile operator not here - every time you switch to another SIM card, the owner will have to reboot the device and, when turning it on, select a different operator. It is clear that at one point in time they can only get through to the card that is active at a given time, not to mention the quick “eating up” of the battery charge.Despite such a huge number of restrictions and shortcomings, the adapter industry does not even think about leaving the market. Another direction has also appeared - the creation of multi-SIM cards that can combine up to several numbers, and not just two or three, like conventional adapters. True, they are much more complicated to produce, and the labor-intensive process also affects the cost of these devices. What awaits us in the future There are rumors that the famous Finnish company Nokia also plans to release a model with support for two SIM cards in the foreseeable future, as Samsung, Fly and even Philips have done before. Of course, it will not introduce this support into every device, but it seems quite likely that several niche models will appear on the market that will be able to introduce an element of healthy competition into already distributed spheres of influence. Perhaps the influence of such a serious market player will bring positive results: other manufacturers will also decide to take such a step, and they will also be supported by software manufacturers for mobile platforms.Another interesting direction is three-SIM phones. So far there are only a few such models on sale, but it is likely that the range of products will expand. As you might have already guessed, on this moment Nowadays, the same Chinese are leading in this direction.Phones with two SIM cards have many supporters and many opponents, but one thing is clear - they leave few people indifferent. And the fact that the number of such models continues to grow steadily, and new players are entering the market, only speaks of their increasing demand and popularity.Today in Russia the number of registered SIM cards significantly exceeds the physical number of users, which means that many subscribers prefer to have several numbers at once. The benefits of such a solution are obvious, since you don’t have to limit yourself to the conditions of choosing one tariff plan, which, for example, may have profitable local calls, but expensive Internet, and vice versa. However, there are no less inconveniences, because in the case of using several SIM cards, a problem arises associated with the need to constantly change them in the phone or, even worse, carry two devices with you at the same time.
Do you have a trap? Where's the trick? One of the dangers of traveling with a smartphone is roaming. If we are not careful and connect to the Internet, it can be really expensive to make a call or connect to the Internet. Although in the European Union they eliminate roaming, what if we travel to another country?
But, as we say, this is also not the norm. Interesting data, communication is on the rise in popularity. Although this is what we want for, we will leave everything well explained. For simplicity, we can say that it is a mobile phone with the ability to function as two, saving space inside for two different numbers.
The optimal solution for a person who often uses different SIM cards may be to buy a phone that supports two SIM cards.
Conventionally, such devices can be divided into three categories:
1. Phones that allow you to work with SIM cards only one at a time, and a reboot is required to switch between them. Thus, the presence of a second slot only saves the user from having to change the card every time.
To differentiate the two numbers installed in the smartphone, we will have the option of assigning a different color to each of them. You can also change the name to have a personal link to which number we are using at any given moment, something very practical.
The biggest disadvantage comes when we want to use the data transfer speed, which is logical considering that smartphones are actually used outside the home. Generally, we can activate data on both cards, but with the following restrictions.
We must select one of the default sockets for high-speed connections. . They have the following characteristics. And with the benefit of connecting all numbers at once, so you can keep them on hold without losing the call. Although you can only use the data on the high speed card installed on your smartphone.
2. Phones that also allow you to work with SIM cards alternately, but to switch numbers they only need to press one button or select the corresponding item in the menu.
3. And finally, phones in which both SIM cards are used simultaneously. In such devices, there is no option to switch between operators as it is unnecessary. Instead, the user simply selects which number to call from.
For example, they can be linked and the tablet can be used to make phone calls. Although we prefer to review a small collection that, in addition to all the guarantees, offers the basic version of this article along with decent services and prices. Nowadays there are many people who have two different mobile numbers.
We will show you two ways to integrate them
After installing the application, you must configure it. That is, you can have a number of workers and staff with corresponding rates. And when it comes to calling or sending messages, you can choose which card to do it from, and if you always use one of them, you can set it from your smartphone's settings. Of course, you can only activate one of the data connections, although you can change them.
year 2000. Benefon Twin is one of the first mass-produced phones initially equipped with two SIM card slots. True, they could only be used one by one.
Until recently, the world's leading manufacturers did not pay attention to devices with support for two SIM cards, which cannot be said about Asian and especially Chinese companies unknown to us. However, among their products there are many counterfeits of well-known world brands. Like, for example, this Nokia N95 clone.
The good news is that you can change the active card in your smartphone's Settings menu. Dual Standby Phones: Both cards are active, but if you call someone on one of the lines, the other will be suspended. If they are inactive, you won't know until you change your card. . We hope we've helped you figure out what to buy!
If you have any doubt, you know, leave it in the comments and we will do our best to resolve it. There are people who even prefer to have two different Accounts for use both at work and simply for their personal use. Unless we jailbreak the phone. The first thing we need to know is that we need two SIM cards with two different phone numbers. We won't go anywhere without this. It is also recommended to have a phone that supports two SIM cards at the same time.
IN 2006 More serious Asian manufacturers are increasingly beginning to pay attention to the market for devices with support for two SIM cards. Thus, the KTF EV-K170 slider, originally from South Korea, was born. It provides hot switching between two SIM cards by simply pressing the corresponding key, but you can still only use one of them at a time.
Although this is not entirely important, it does make the work more comfortable. In case our phone only has a SIM card, we will need to receive the activation message on the other phone.
