The network has disappeared on iPhone 5s, it's worth searching. iPhone can't connect to the network? Damage to the modem part and eternal search for the network
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 cellular network. Let's try to figure out what causes the “breakdown” in such cases and how to fix it.
In contact with
The problem is aggravated by the fact that employees of service centers in Russia, Ukraine, Belarus, etc. are not always able to identify the real reason for the lack of connection to the cellular network (or deliberately hide it) and carry out a number of expensive procedures - ranging from simple iOS reinstallation and ending with 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 correctly current time and date, then you need to perform the following simple algorithm of actions:
1 . Connect your device to active Wi-Fi networks;
2 . Go to Settings → Basic → date and time ;
3 . Toggle the " Automatically" V 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 network cellular communications, 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.
Let us repeat - this situation has nothing to do with the 4G coverage of 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 mobile 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. Don't 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.

After unsuccessful manipulations with the phone (firmware reinstallation, repair, or a long period of inactivity of the device), problems with the mobile operator’s network may appear on the IPhone. The signal may be too weak or completely absent. If your iPhone stops receiving the network, use the following methods to solve the problem one by one.
Method number 1 - Take out the SIM card
The lack of an operator’s network causes a lot of inconvenience to users, because the ability to make calls, write SMS, etc. disappears. The first method is quite simple - you just need to turn off the phone and use a paper clip to get sim card from the body. Next, you need to reinstall the card and turn on the device.
