Many iPhone users often have the problem of network disconnection, which leads many to panic and haunts them.
You need to reboot your smartphone using a deep reboot, for which you will need to press the Home key simultaneously with the “Shutdown” key. The phone may work better due to full reset all network parameters and updating them, but if this does not happen, you can try several other methods.
Causes and actions when identifying a problem
You need to carefully remove the SIM card and make sure the contacts are completely clean. They can be blown off with compressed air.
Another reason for this problem may be that many buyers of these phones, without thinking at all about the consequences, can damage the SIM card contacts when cutting it. This procedure must be carried out with the help of a specialist in an authorized store.
Another way to restore connectivity on your iPhone is to connect to Wi-Fi and set the correct date and time, which you can quickly do in the settings menu. You can try turning airplane mode on and off a couple of times, which can often help you out.
Fixing the problem with factory unlocking
The most common cause of the error is unlocking using the Ultrasnow program or updating the firmware to the iPad version. This is not at all related to the hardware, since the “no network” error means that the smartphone has accepted the SIM card, but there are obstacles to receiving communication in the software structure itself.
One of the most popular and correct solutions to the problem is resetting the network settings via General settings. You can also try to delete information, which may damage the existing program code.

To do this, go to settings and activate automatic search networks, that is, we search for the network manually.
Our article is devoted to the “symptoms” of such a problem, as well as providing first aid to your mobile device.
The fact is that in some cases, contacting a specialist may not be necessary, since the user is quite capable of troubleshooting the problem on his own.
Signs of a problem
- It happens that on our device we see an inscription indicating that there is no network, but at the same time we are in a network coverage area with an excellent signal.
- It also happens that a smartphone loses connection when it is outside the coverage area, but after returning there the connection does not appear.
- Another indicative symptom is the situation when the word “Search” is displayed in the status. In addition, when you go to the main settings, the “About this device” menu, you will notice the absence of any information in the “Firmware” item.
Solutions
- If we encounter one of the above alarming symptoms, or the network is absent under any other conditions, it is worth trying to perform the following manipulations sequentially.

Sometimes users encounter this problem while on a trip, using roaming, after a hardware repair (battery or display replacement) of the smartphone or a long period of inactivity (without recharging) - the operator logo disappears on the iPhone and there is no connection to the cellular network. Let's try to figure out what causes the “breakdown” in such cases and how to fix it.
The problem is aggravated by the fact that employees of service centers in Russia, Ukraine, Belarus, etc. They are not always able to identify the real reason for the lack of connection to a cellular network (or deliberately hide it) and perform a number of expensive procedures - from a simple reinstallation of iOS to hardware repairs using a soldering iron and other “jewelry” tools.

Check if the SIM card is working?
Unfortunately, SIM cards also fail. Therefore, first of all, check whether the SIM card works in your iPhone. This can be done, for example, by installing a SIM card in another smartphone.
What to do if instead of the operator on the iPhone it says “no network” or the smartphone does not see the SIM card after repair (flashing)
If the problem described above occurs, first of all you need to look at set time- if the smartphone does not display the current time and date correctly, then you need to perform the following simple algorithm of actions:
1 . Connect your device to an active Wi-Fi network;
2 . Go to Settings → Basic → date and time ;
3 . Toggle the " Automatically» to the active position (if set by default, turn it off and on);
4 . Restart your iPhone.
No network, search or what to do when the iPhone does not see the operator’s SIM card while roaming abroad
If you've ever traveled abroad with your iPhone, you might have encountered this problem. You turned off your smartphone during the flight, and when you turned it on, your device does not connect to the cellular network, but displays the message “No network.” What to do?
On the technical forum Apple support there is a corresponding discussion thread with a million pages to read. But even if you honestly start reading everything to figure it out, you won’t get an answer to your question even after several hours of careful reading.
System message “No network” (Search for network) appears when your iPhone or iPad (yes, the problem is also relevant for Apple tablets) cannot connect to it, or connects to an operator, but cannot establish a connection to either the Internet or the cellular network. You may even see the name of the operator who serves you - but then it will disappear anyway.
This error can have several reasons. But first you should exclude the most common and simplest of them. And anyone can do this.
Switch from LTE (4G) to 3G
1 . Open Settings your iPhone or iPad.
2
. Select cellular
→ Voice and data. 
3
. Click on the inscription Voice and data and change LTE to 3G or 2G.
Why do you need to do this? Experience shows that not all mobile operators abroad provide roaming in fourth generation networks (4G / LTE). As a result, and logically, your iPhone or iPad does not connect to networks - simply because there is nothing there for “foreigners”. AND the simplest way to solve this problem - look for networks of the previous, third generation (3G), because it is difficult to imagine a more or less developed country where they do not exist.
We repeat - this situation has nothing to do with 4G coverage foreign operators. They can provide fourth generation networks to local subscribers, but not to visitors.
Try it - it really helps :).
Did not help?
Well, let's look at the options for solving the problem from among those that Apple offers us.
1. Turn off and on your iPhone (iPad)
2. Update your carrier settings
For this:
— Connect to the Internet via Wi-Fi or a cellular operator.
— Select Settings → Basic → About this device. If your operator has prepared a settings update, you will be prompted to update to them.
3. Take out the SIM card and insert it back
4. Reset network settings
Settings → Basic → Reset → Reset network settings. Do not forget that this operation resets passwords for Wi-Fi networks, cellular network settings and preset VPN/APN settings.
5. Update iOS on iPhone and iPad to the latest version
6. Contact your mobile operator for help
Check with him whether the account is active or not technical problems with connections in your region.
7. Reset your iPhone or iPad to factory settings
What to do if the Internet does not work on iPhone while roaming
1. Go to Settings → cellular and see if the slider next to the inscription is enabled Cellular data.
2
. If you are abroad, check that your data roaming settings are active ( Settings → cellular → Data Options → data roaming).
Please note that the cost mobile traffic in roaming is much higher.
Like these ones simple methods in some cases, they will help you avoid a trip to the service center and save a decent amount, which could have been billed by unscrupulous specialists.
Finding yourself “in your hands” with an iPhone that does not catch the network on any trip or business trip is not a pleasant situation. The boss will be annoyed that his employee is unavailable and did not submit a timely report, relatives will be worried, potential clients get off the hook. It will be impossible to even call help or a taxi if something happens to the car. It should be recognized that modern man is heavily dependent on the GSM signal.

Step 4. Restart your iPhone and check the network.
If you have access to Wi-Fi, you can avoid manual settings time. In the “Date and Time” subsection there is an “Automatic” slider. After activating it, the iPhone independently determines the time in the set time zone - but only if the gadget is connected to the Internet.
Your humble servant prefers not to use automatic tuning time, because his iPhone “counts” an hour too late.
Problems with mobile operator settings
If the time is set correctly, but the iPhone still does not receive the network, you can suspect that the settings of the cellular operator have gone wrong. A set of such measures will help solve this problem (each subsequent step should be performed only if the previous one did not produce results):

There are areas where the signal is very poor in large cities. As a rule, iPhones are not detected in the subway, basements, or elevators. The network may disappear inside the building due to the fact that the concrete walls of the room jam the GSM signal. Some buildings deliberately use “jammer” devices to prevent employees from excessive Internet surfing. The jammers look something like this:
Previously, “jammers” were readily placed in educational institutions. Now the use of such devices has been reduced to a minimum - the modern educational process requires the student to actively access the mobile Internet.
If the GSM signal is weak in the user's home, this is a reason to file a claim with the communication provider. The owner of the iPhone needs to call the number hotline and complain about the lack of network. The application will be transferred to the technical department, whose employees will make every effort to resolve the problem.
SIM card is damaged
Mechanical damage to the SIM card or its incorrect cutting can not become the reasons why there is no network on the iPhone. If the card is faulty, the SIM gadget will not recognize it at all. This is a completely different problem possible solutions which we proposed in the article “”.
However, a user suffering from a lack of network on a smartphone should still conduct a visual inspection of the SIM card. If there is dirt on the contacts, you need to carefully remove it. Even the fact that the user removed the SIM card and installed it back in the slot can help restore a normal GSM signal.
If the owner of an iPhone has suspicions that the gadget has poor network reception due to the SIM card, he should contact the service office with a passport and have the SIM replaced. This procedure is free and only takes a couple of minutes.
iOS crash
The failure of the above measures tells the user that the problem may be software. For the gadget to work correctly, you need Latest updates systems. To check if there are any updates available, the user needs to follow the path “ Settings» — « Basic» — « Software Update».
The gadget has broken down
If there is a physical breakdown of the iPhone, a visit to the specialists cannot be avoided. As a rule, a gadget’s failure to catch the network is caused by a malfunction of the antenna module. A broken antenna is the result of a fall or flooding of the gadget. The cost of repairs in this case will depend on iPhone models. We will collect the approximate prices in a table:
