What to do if Android cannot see the SIM card? (Topic)

This error usually occurs when a new SIM card is inserted into the slot, and the most common cause of this error is damage to the slot, the card itself, or its incorrect position.

But it happens that the card is installed correctly, the slot is intact, but there is no connection. And then you can rearrange the map indefinitely, but until you figure out what the problem is, you won't be able to connect.

So what can you do?

01. Restart Smartphone
