Iphone 7 Doesn'T See Sim
Sometimes users encounter such a problem while traveling, using roaming, after reinstalling iOS, hardware repair (replacing the battery or display) of the smartphone or a long period of inactivity (without recharging). the operator’s logo disappears on the iPhone and there is no connection to the cellular network. Let’s try to figure out what in these cases is the cause of the “breakdown” and how to fix it.
The problem is aggravated by the fact that employees of service centers, Ukraine, Belarus, etc. far from always able to identify the real reason for the lack of connection to the cellular network (or deliberately hide it) and perform a number of expensive procedures. from simple reinstallation of iOS to hardware repair using a soldering iron and other "jewelry" tools.
Check if a working SIM card?
Unfortunately, SIM cards also fail. Therefore, first of all, check if 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)
In the event of the described problem, first of all, you need to look at the set time. if the smartphone does not correctly display the current time and date, then the following simple algorithm of actions must be performed:
1. Connect the device to an active Wi-Fi network;
2. Go to Settings → The main → date and time;
3. Toggle the "Automatically»In the active position (if set by default. turn it off and on);
4. Reboot your iPhone.
No network, search or what to do when the iPhone does not see the SIM card of the operator while roaming abroad
If you have ever traveled abroad with your iPhone, you might run into such a problem. You turned off the 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?
The Apple Technical Support Forum has a corresponding discussion thread with a million pages to read. But even if you honestly begin to read everything to figure it out, you won’t get an answer to your question even after several hours of attentive reading.

System message “No Network” (Network Search) appears when your iPhone or iPad (yes, the problem is also relevant for "apple" tablets) cannot connect to it, or connect to the operator, but cannot establish a connection to the Internet or to the cellular network. You can even see the name of the operator that serves you. but then it will disappear anyway.
This error can have several reasons at once. But first, the most common and simplest of them should be excluded. And everyone can do it.
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 just that? Experience shows that not all mobile operators abroad provide roaming in fourth-generation networks (4G / LTE). As a result, which is logical, your iPhone or iPad does not connect to networks. simply because for "foreigners" there is nothing there. And the simplest way to solve this problem is to look for the networks of the previous, third generation (3G), because it is difficult to imagine a more or less developed country where they do not exist.
Once again, this situation has nothing to do with the 4G coverage of foreign operators. They can provide fourth-generation networks to local subscribers, but not visitors.
Try it. it really helps :).
Well, let’s look at solutions to the problem among those that Apple offers us.
1. Turn off and on the iPhone (iPad)
2. Update operator settings
3. Remove the SIM card and insert it back.
4. Reset network settings
Settings → The main → Reset → Reset Network Settings. Do not forget that this operation resets passwords for Wi-Fi networks, cellular network settings and predefined VPN / APN settings.
5. Update iOS on iPhone and iPad to the latest version (in detail)
6. Contact your mobile operator for assistance.
Check with him if the account is active, if there are any technical problems with communication in your area.
7. Reset iPhone or iPad to factory settings (detail)
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 enabled Cell data.
2. If you are abroad, check if data roaming settings are active (Settings → cellular → Data options → data roaming)
Keep in mind that the cost of mobile traffic in roaming is much higher.
These simple methods in some cases will help to avoid going to the service center and save a decent amount, which could be invoiced by specialists who are not at hand.
