Clean SIM card
One of the first things to do when the SIM card is not recognized on the Xiaomi Mi A3 is to clean it. In fact, it often happens that dirt blocks the contact between the SIM card and the mobile phone. So if you want to clean it, put a rag on it and check that it’s not damaged.
Examine the location of the SIM card on the Xiaomi Mi A3
Sometimes the problem comes from where you put your SIM card. In fact, it always happens that the mini metal plugs that need to touch the SIM card are naturally a bit relaxed. When it does, it prevents the Xiaomi Mi A3 from reading the SIM card. To solve this problem, you just need to slightly thicken the SIM card by sticking one or two pieces of adhesive tape on the back.
Try the SIM card in a second mobile
To find out if the problem is in your SIM card, you should try it on a second phone and you will have your answer. If it is not recognized on other devices, you can replace the SIM card.
Try another SIM card in Xiaomi Mi A3
Assuming that the 2 previous phases do not work, it is enough to try another SIM card to know if the problem comes from the card. And yes, if other SIM cards are recognized on the Xiaomi Mi A3, it means that the problem is with the card. Instead, we will have to look at the device.
Make sure the Xiaomi Mi A3 is not a Simlocker
If you have tried several SIM cards in your Xiaomi Mi A3 and none of them are recognized, it is likely that your phone is Simlocker. This means that the Xiaomi Mi A3 can only recognize SIM cards from a specific operator. In this case, you need to unlock it. You will easily find many offers on the Internet that can do just that.
Check if the problem does not come from the ROM installed on Xiaomi Mi A3
This step mainly applies to people who have rooted Xiaomi Mi A3 to install non-original ROM. When this is actually what you have done, you should know that SIM card not recognized issue is quite common after installing new ROMs. Therefore, we recommend that you reinstall an original ROM and try it again.
if nothing works
If all the above tricks don’t work, we recommend that you take your Xiaomi Mi A3 and the SIM card to one of your phone company’s stores.
