My mobile does not detect the SIM card, what do I do?

The problems with SIM card on Android mobiles They are more common than it may seem at first. Inserting the card in the phone and not recognizing it is a relatively common problem.

And quite important, because it means that we can not use the phone to call. Luckily, there are several small solutions that you can consider.

What to do if your SIM card doesn't work

Try the card on another phone

The first thing you should do is check if the problem comes phone or card per se. To do this, the easiest thing is to try inserting the SIM into a different device.

If it works this way, it is clear that the fault is in our smartphone.

In the event that the card does not work on another smartphone either, we always have the option of asking our operator for a duplicate.

Check that the SIM card is inserted correctly

It may seem absurd, but it happens more than we think. If you have removed the card from the phone or have inserted a new SD, it is easy that when you put it back in you make a small mistake.

Therefore, if you see that the phone does not recognize your SIM, before panicking you should check that everything is in place. This way you will avoid problems in advance.

Make sure you are connected to the correct network

Many times, when the 4G connection does not work, it is not due to problems with the SIM card, but because we have selected the wrong connection type. To check it, you must enter the phone Settings and then access Networks and connections>Mobile Networks>Type of network.

There you can change the type of network that your phone is configured for. And if you match the connection type to the type of card you have, the problem should be fixed.

Check the APN settings

Another option why the SIM card might not be working is that the APN are misconfigured or not configured at all.

To check it you will have to enter the Settings of your smartphone and then select Networks and Wireless Connection> Networks> APN. You will have to check that the settings match those of your operator.

In the event that none of these means is useful for your smartphone to recognize the SIM card, you always have the possibility of restoring the device to factory settings. In this way, it will return to the way you took it out of the box, so it is possible that the problem that prevented it from working correctly will solve itself.
