Instructions for correctly installing a SIM card in any phone. Instructions for correctly installing a SIM card in any phone How to change a SIM card in Samsung

In this article we will tell you how to correctly insert a SIM card into your phone yourself. New modern models are coming out with convenient slots into which cards of the required size can be inserted without problems.

And all popular mobile operators produce unique constructors - SIM cards in three popular sizes: nano, micro and standard.

SIM cards are a subscriber identification module of a telecom operator. Several decades have passed since their launch until the start of mass sales, and during this time their shape and size have improved. This process was forced. First on mobile markets smartphones appeared, and places for back cover the details were simply lacking. Technologies have improved, user demands have increased, batteries are larger, phones are thinner, and there is less space.

This evolution of cards allowed them to be reduced by almost half, and modern retractable slots significantly freed up space for other parts.

Let's look at what types of sim there are, what their features are, and how to insert a sim:

• Full-size (which many people didn’t even know was available) is the largest in the line, along the perimeter as bank card. Appeared in 1991 with the first wave of popularity cellular communications among ordinary residents. It is not used in modern phones; sometimes you can find cars with similar “innovations” a la the 90s.
• Mini-SIM - still used for devices manufactured from the 2000s to the early 2010s, supports 2G and 3G.
• Micro-SIM - appeared in 2003, but on this moment considered the most used generation of communication modules. Supported by all manufacturers of modern gadgets with 3G and LTE.
• The smallest is the Nano-SIM, which looks like its predecessor, but without the plastic edges. It appeared five years ago and is used in all models of the Apple brand and some other premium segment manufacturers.

All types of SIM cards are inserted the same way - into the designated slots in a smartphone or tablet. It is impossible to say exactly where the stand is located, since manufacturers reserve the right to place them anywhere, according to their design concept. Sometimes new phones have a sticker with step by step instructions, it can also be found in the User's Guide.

Installing a SIM card

Traditionally, manufacturers place card holders on the right side of the case (if the cover is not removable), or directly under the battery, if it is removable. The following instructions are suitable for owners of the latest type of gadgets:

1. Check if your phone is turned off.
2. Detach the back panel.
3. Locate the small indentation between the case and the battery.
4. Remove the battery.
5. There you will see SIM card slots. They are different types: separate and two-story. The side you want to hold up when inserting will be shown next to the holder. As a rule, it is inserted with the gold contacts facing down.
6. Carefully insert the battery back. Check that it fits snugly.
7. Return the lid until you hear a characteristic click. They will mean that the lid is in place.

In the video you can see what to do with modern models whose lids cannot be removed:

Settings

Modern smartphones and SIM cards do not need manual connection. When starting for the first time on a new device from mobile operator the package will arrive free settings for all types of cellular services.

For dual-SIM mobile devices, the controls can be a little difficult for a beginner. You can choose a SIM for certain actions by default, or choose it yourself for every call and message.

Will a regular SIM card fit into the micro-sim slot?

You can cut a regular size card to micro-sim dimensions if the card is old. However, it is much easier and safer to contact service center, where you will be given a new SIM in the form of a transformer - all popular sizes.

If the module urgently needs to be replaced with a smaller one, you can cut it manually with ordinary sharp scissors.

What to do with a poorly cut SIM card

However, such experiments do not always end successfully. If the SIM card was cut incorrectly and was damaged in the process, you must contact the customer service points of your mobile operator. Replacing the card with another SIM while maintaining the balance, tariff plan and, directly, the numbers do not take long.

It is not recommended to insert a SIM that has mechanical damage.

SIM card malfunctions

Users guess about their malfunction when the OS does not see the module and does not indicate it with the corresponding icon. The reasons may be:

• The SIM has expired and is not intended for further use.
• It has mechanical damage - scratches, chips and breaks.
• Failed trimming. We mentioned it above.
• The phone's firmware is tailored for a specific buyer.
• Problems with the slot.
• Crashes in operating system and software.
• The contacts were damaged during installation.
• Dirt got on the card holder.

In most cases, the card needs to be replaced, or the phone needs to be sent to a technician for diagnostics, as these can be either hardware or system problems.

Conclusion

Mobile communications and the Internet are available throughout the day thanks to smartphones and small card modules issued by cellular providers. That is why they need to be treated with care, monitored for their condition and serviceability. The more gadgets come out, the easier it becomes to use SIMs - their sizes decrease, and their capabilities increase. We hope you found this article helpful and provided easy-to-understand instructions on how to handle them in different situations.

You will need a suitable SIM card for the Galaxy S8 and S8+ and you need to use it correctly.

This guide will tell you: what size is used, how to insert and change the SIM card, and how to use two SIM cards in versions Dual SIM.

What is the correct SIM card size?

To make phone calls or use mobile data, you will need a SIM card (subscriber identification module), which can be obtained from any telecom operator (MegaFon, MTS, Beeline, Tele2, etc.).

Technically, for mobile phones there are 4 different sizes kart:

1. Full size SIM card. Often referred to as 1FF (1st form factor). This is a "giant" size: 85.60 mm × 53.98 mm × 0.76 mm. You probably won't be able to find it in the market and no Android phone has used this size.
2. Mini-SIM (2FF). In some countries it is usually referred to as a "large", "normal" or "standard" SIM card. Most carriers and phone manufacturers phased them out several years ago.
3. Micro-SIM (3FF). Still the most popular size for smartphones. Most average and budget smartphones use this card. In some regions it is called a “small” SIM card.
4. Nano-SIM (4FF). This is the smallest » map available today for smartphones. For most flagship smartphones This is exactly what is required.

Galaxy S8 and Galaxy S8+ use Nano-SIM card.

If you have just purchased new flagship from Samsung, and before that you used another phone, then you may have already used a nano SIM card in it.

For example, some popular phones using nano-SIM: Galaxy S7 (edge), Galaxy Note 5 and 7, Galaxy S6 (edge, edge +), iPhone 7 (7+), iPhone 6S (6S+), iPhone 6 (6+), iPhone 5, Moto X (including all generations) and many others. If you had/have any of these phones, the SIM card will work for the Galaxy S8 (S8+) too.

You can always get a Nano-SIM from your operator (preferably), but you can cut the Micro-SIM card yourself to the desired size, for example, using a special cutter or a stationery knife.

What is slot 2 in the SIM card tray?

As shown in the picture below, the tray has two slots, regardless of region.

Slot 1 is always for the SIM card.

However, slot 2, which is larger, may be used differently depending on your region and model.

Slot 2 is used for Micro SD memory cards and only in the Dual SIM version (model availability depends on your region) you can insert a second nano-SIM card into it.

How to insert a SIM card?

To insert SIM card into Galaxy S8 and S8+, you need to follow the following 5 steps as shown in the image below.

Step 0: Turn off your phone.

Step 1: Insert the special tool (included) into the hole on the tray and push it all the way down to loosen the tray.

Step 2: Carefully pull out the tray.

Step 3: Place the SIM card in slot 1 with the metal parts facing down.

Step 4: Secure it.

Step 5: Reinsert the tray.

Step 5/1: Turn on your phone.

How to remove or replace the SIM card?

You can remove or replace the SIM card, similar to the instructions discussed above.

How to use two SIM cards in the Dual SIM version?

For the dual SIM version of the Galaxy S8 or S8+, you are allowed to use 2 SIM cards at once.

Please note that there are some restrictions:

• This only works in Dual SIM version.
• You cannot use a micro SD card when using two SIM cards at the same time.
• Technically they have dual standby modes rather than two active modes. But in some mobile networks, where 2G is phased out, both SIMs can connect to 3G/4G networks and both can work simultaneously as active dual SIM phones. Whether it can work like this depends on your operator's network.

In the dual-SIM version, control is carried out in the “Settings - SIM card manager” menu. You must specify which SIM is for mobile data (although both can connect to 3G/4G networks) and which will be the default for calls and messages. These settings can be changed at any time.

Samsung decided to listen to the opinions of its fans and returned memory card support to the new flagship devices Galaxy S7 and Galaxy S7 Edge. However, she did this using a hybrid slot, as has become fashionable recently. This means that the user must choose whether to use 2 SIM cards or one SIM card and a microSD card in the smartphone. Fortunately, there were craftsmen who discovered that the contacts of the second SIM and the contacts of the memory card are in different places and managed to combine business with pleasure and organize the simultaneous operation of two SIM and microSD cards. And if you have decided to become the owner of a new device (or have already become the owner), despite all its minor disadvantages, then this article is for you. We are publishing a translation of instructions with detailed comments on installing two SIM cards and a memory card in the Galaxy S7 and Galaxy S7 Edge.

Denial of responsibility: You do all the manipulations listed below only at your own peril and risk. Neither the author nor anyone else is responsible for your actions or for any damage caused. There is a high probability of damaging the SIM card microchip, and to a lesser extent, the microSD memory card. Also, when the smartphone heats up, there is a danger of this structure coming off, and in this case problems may arise when removing the tray. It is quite possible that you will have to contact a service center to get it. In this case, the device is removed from warranty.

So, if you are aware of all the risks listed, then to continue you will need the following devices:

• SIM card in Nano format (because it is easier to cut and “disassemble”)
• microSD memory card
• Lighter
• Scissors, blade or any other sharp object
• Thin double-sided tape (preferred) or super glue
• A little free time, patience, a head on your shoulders and straight arms

To install two SIM cards and a memory card at the same time in Samsung Galaxy S7 or Galaxy S7 Edge requires:

• Determine the correct position of the SIM card
  First, you will need to determine the correct position of the SIM card in the tray. Cards from different operators may have different contact configurations. The author of the original instructions carried out operations on SIM cards of U Mobile and Maxis operators (Malaysia). Typically, all SIM cards have a special key on one side (cut corner).

• Detach the SIM card chip from the base
  Any SIM card consists of a plastic base and a microchip with a contact pad glued to it. Gently heat the SIM card from the opposite side (where the plastic is). This may take from 30 seconds to 1 minute. Then carefully separate the chip with the contact pad from the base. It is recommended to use a sharp object (scissors, knife, blade, etc.) as an auxiliary tool. After this, the chip must be cleaned of any remaining glue or plastic.
  If everything went smoothly and you did not have to change the SIM card, then you can consider half the journey completed.

• Trim the SIM card microchip
  Now you need to carefully cut the contact pad of the SIM card to fit on the memory card. Usually you need to shorten it by 1-2 mm on each side (as in the photo).

• Secure SIM card to microSD
  This can be done using double-sided tape (in which case the memory card can be easily (more or less) “freed”) or super glue (this option is less preferable, since if you damage the SIM card chip, then separate it from the memory card will be quite difficult or even impossible). The first step was provided for correct placement. In addition, make sure that the corner of the SIM card microchip is aligned as shown in the image (circled in red).

• Place the finished structure in the tray
  Now all that remains is to place the genetically modified microSD card into the tray, and the tray itself into the smartphone.

Finally, you need to check that all actions have been performed correctly. If everything is done correctly, the Galaxy S7 will “see” two SIM cards and a microSD memory card. It will look something like this:

It is also worth noting that the method described above is suitable for all smartphones with the same hybrid SIM card tray. In particular, the owners have similar experience Meizu Pro 5.

It would seem that placing a SIM card in the Samsung Galaxy S7 is not so difficult. However, it is not surprising that new smartphone owners who have switched to this model from other, earlier ones have a similar question. The point is that, starting with models Galaxy lines S6, Samsung decided to combine a SIM card slot and microSD cards. As a result, the phone body became monolithic, and the cards acquired a new location. And if previously it was enough to simply remove the cover of the smartphone and insert the SIM card into a special recess, now you can rack your brains quite a bit before finding the right compartment and placing the card there.

How to insert a SIM card into Samsung Galaxy S7

If your device is in active mode, we advise you to first turn off the device. This will prevent the possibility of various errors appearing in the operation of the gadget in the future.

How to remove a SIM card from the slot

In order to perform the reverse operation, that is, remove the SIM card from the device, you need to perform the following steps:

1. To avoid data loss or incorrect operation phone, first turn off your device.
2. Take the key that came with your Samsung Galaxy S7, or a regular paperclip. Don't forget to straighten it first. Insert a key or paper clip into the special hole in the SIM card tray cover. Apply light pressure and when the tray comes out a little from the body, pull it towards you.
3. Once you have the card slot in your hands, remove the memory card or second SIM card (if installed) from it.
4. Then you can pull out the desired SIM card. When performing these steps, be careful, because rough handling of the equipment can damage the contacts and lead to improper operation of the device.
5. Once you have removed the SIM card, carefully place the card tray back into the phone. To do this you just need to insert it right side into the slot and press down a little so that the tray is fixed in the body.

In the end, it turned out that inserting a SIM card into the Samsung Galaxy S7 is actually not that difficult. It is enough to know where the card slot is located, as well as be a little patient and careful during installation.

Most manufacturers modern phones They are gradually abandoning SIM cards of the old Mini-SIM format. They are being replaced by compact Micro- and Nano-SIM. This approach makes it possible to reduce the size of mobile devices and make them more convenient to use. In this aspect, Samsung did not invent anything new and equipped its Galaxy smartphone A5 slot for Nano SIM card. And if you decide to purchase this device to replace an outdated mobile phone, be prepared for the fact that you will have to cut the card you have on hand. Let's figure out how to correctly insert a SIM card into the Samsung Galaxy A5.

Specific features of the SIM slot in the Galaxy A5

Today there are several modifications Samsung smartphones Galaxy A5. They differ from each other not only technical characteristics, but also the location of the SIM card slot and its capabilities:

• Galaxy A5 phones released before the beginning of 2016 have two connectors. The first one is for installing Nano-SIM. The card placed in it will be determined by the system as the main one. The second tray is hybrid, that is, you can insert either a second SIM card into it, or expand the memory using Micro SD. Both card readers are located on the right side of the mobile phone.
• Gadgets from 2016 have one hybrid connector located on right side device under the Power key. As in the first case, you can install two Nano-SIM or SIM+Micro SD in it.
  
  
• New modifications, released in 2017, are equipped with two slots. The first (main), located on the left side of the Samsung, accepts Nano cards. The second tray is located at the upper end and is complex. Thanks to this approach, you can simultaneously fit two SIM cards and Micro SD memory into the phone.
  
  

In all modifications of the Galaxy A5, the connectors are opened using a metal ejector included with the device. However, if it is not available, you can use a regular staple, having first straightened one of its ends, or a needle.

Trimming SIM card for Samsung Galaxy A5

If you have a Mini or Micro SIM card on hand, you will need to cut it to Nano format before installing it. Here you need to choose one of three options:

If the third option was chosen, to accomplish your plan you will need the following tools and materials:

• b/w or color printer;
• sharp knife or scissors;
• sandpaper;
• blank A4 sheet;
• cutting template;
• tape or PVA glue.

The sequence of work will be as follows:

The SIM card can be inserted into the phone.
