SIM card not recognized
If you see   or   in the status bar or a message that the SIM is not recognized:
1. Turn your phone off and then on again.
Press the Power + Volume up buttons simultaneously, then touch Restart to establish a new 
connection with the network.
2. Do one of the following:
•
If your phone allows one SIM card, turn your phone off, then remove and reinsert the SIM.
•
If your phone allows dual SIMs, disable the SIM, then enable it again. Go to Settings > Network & 
internet > SIM preferences. Turn the SIM off  . Then turn it on  .
If one of the two SIMs is working, remove the SIM that is not recognized and try it in the other SIM 
slot. If it doesn't work in the other SIM slot, then the issue is with the SIM card and you need a 
replacement from your carrier.
3. Contact your carrier to make sure your account is set up properly.
4. Ask your carrier to replace the SIM card.
5. Perform an external phone reset.
