No network, search, or why the iPhone cannot see the SIM card from the operator

No network, search, or why the iPhone cannot see the SIM card from the operator

Sometimes users face this problem when traveling, roaming, after reinstalling iOS, hardware repair (replacing battery or screen) of mobile phone, or long period of inactivity (without recharging): the iPhone does not have the carrier logo and does not connect to the cellular network. Let's try to figure out what is the cause of the “malfunction” in these 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 cause of the lack of connection to the cellular network (or they deliberately hide it) and perform a series of expensive procedures, from the simple reinstallation of iOS to repairing the hardware with a soldering iron and other repair tools. "jeweler's".

Check if the SIM card works?

Unfortunately, SIM cards also fail. So the first thing you should do is check if your iPhone SIM card is working. This can be done, for example, by inserting the "SIM" in another mobile phone.

No network, search or what to do when iPhone can't see SIM card when roaming abroad

If you have ever traveled abroad with your iPhone, you may have encountered this problem. You have turned off your smartphone during the flight, and when you turn it on, your device does not connect to the cellular network, instead it gives the message “No network”. To do?

There is a relevant discussion thread on the apple support forum with a million pages to read. But even if you sincerely read everything to find out, you won't get an answer to your question even after a few hours of careful reading.

system message “No network” (Network search) appears when your iPhone or iPad (yes, yes, the problem also affects apple tablets) cannot connect, or connects to the operator, but cannot establish a connection to the Internet or the cellular network. You may even see the name of the operator who is serving you, but then it just keeps disappearing.

This error can have several causes at once. But first you need to remove the most common and simple. And that can be done by anyone.

Switch from LTE (4G) to 3G

1. To open Settings of your iPhone or iPad.

2. Choose Cellular communication → Data settings.

3. Go to the section Voice and data and switch from LTE to 3G or 2G.

Why do you have to do it like this? Experience shows that not all mobile phone operators abroad offer roaming on fourth generation networks (4G / LTE). As a result, and logically, your iPhone or iPad will not connect to the networks, simply because there is nothing for "foreigners". And the easiest way to solve this problem is to look for the old networks, third generation (3G), because it is difficult to imagine a more or less developed country without them.

Again, this situation has nothing to do with the 4G coverage of foreign operators. They can give 4G networks to local subscribers, but not to travelers.

Give it a try, it really helps :).

It has been useless?

Well, let's see the solutions to the problem among those offered by Apple.

1. Power cycle iPhone (iPad)

2. Update carrier settings

For that:

– Connect to the Internet via Wi-Fi or mobile phone operator.
