Sometimes users face such a problem while traveling, using roaming, after, hardware repair(replacing the battery or display) of a 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 is the cause of the "breakdown" in such cases and how to fix it.
In contact with
The problem is aggravated by the fact that the employees of service centers in Russia, Ukraine, Belarus, etc. are not always able to identify the real reason lack of connection to the cellular network (or deliberately hide it) and perform a number of expensive procedures - from a simple reinstallation of iOS and ending with hardware repair 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 if the SIM card in your iPhone works. 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 described problem occurs, first of all you need to look at set time- if the smartphone does not display correctly current time and date, then it is necessary to produce the following simple algorithm of actions:
1 ... Connect your device to active Wi-Fi networks;
2 ... Go to Settings → The main → date and time ;
3 ... Toggle the checkbox " Automatically»In 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 have ever traveled abroad with your iPhone, you may have encountered such a problem. You turned off your smartphone during the flight, and when you turned it on, your device does not connect to the network cellular, and displays the message "No network". What to do?
At the forum of technical Apple support there is a corresponding thread with a million pages to read. But even if you honestly start reading everything in order to figure it out, you will not get an answer to your question even after a few hours of careful reading.
System message "No network" (Search 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 either to the Internet or to the cellular network. You can even see the name of the operator who serves you - but then it will disappear anyway.
This error can have several reasons at once. But first, you should exclude the most common and simple of them. And anyone can do it.
Switch from LTE (4G) to 3G
1
... Open up Settings your iPhone or iPad.
2
... Please select cellular → Voice and data. 
3
... Click on the inscription Voice and data and change LTE to 3G or 2G.
Why should you do this? Experience shows that not all mobile operators abroad provide roaming in 4G / LTE networks. As a result, which is logical, your iPhone or iPad is not connected to networks - simply because there is nothing there for "foreigners". AND the simplest way to solve this problem - to 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's repeat - this situation has nothing to do with 4G coverage of foreign operators. They can provide 4G networks to local subscribers, but not to newcomers.
Try it - it really helps :).
Did not help?
Well, let's look at some of the solutions that Apple offers us.
1. Turn off and on your iPhone (iPad)
2. Update operator settings
For this:
- Connect to the internet via Wi-Fi or cellular operator.
- Select Settings → The main → About this device... If your operator has prepared an update to the settings, you will be prompted to update to them.
3. Take out the SIM card and insert it back
4. Reset network settings
Settings → The main → Reset → Reset network settings... Keep in mind that this operation resets Wi-Fi passwords, cellular network settings, and preset VPN / APN settings.
5. Update iOS on iPhone and iPad to the latest version
6. Contact your cellular operator for help
Check with him if the account is active, if technical problems with a connection in your area.
7. Reset 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 opposite the inscription is turned on Cellular data.
2
... If you are abroad, check if the data roaming settings are active ( Settings → cellular → Data parameters → data roaming).
Please note that the cost mobile traffic much higher in roaming.
Like these ones simple methods in some cases will help to avoid going to service center and save a decent amount, which could be invoiced by not clean on hand specialists.
