SIM Card Registration Failed

Fix the SIM Failure Issue on your Mobile

Some tweaks can fix SIM failure to some extent. If you are facing the SIM Card Registration Failed issue, follow the below steps one by one to get the sim card failure issue fixed.

Restart the Mobile

For all smartphone-related issues, restarting the handset is the primary step to start troubleshooting. If the problem is minor and due to some small software-related bug, it will get rectified by the restart. So reboot your smartphone and check whether the sim card registration issue is fixed.

Reinsert the SIM Card

If the restart doesn’t fix the problem, proceed with the SIM card reinsert step. Switch off the handset and try removing and reinserting the SIM card on your mobile. Then power on the device. Check whether you are getting a signal on your mobile. If the problem still exists, proceed with the next step.

Check with your service provider

The next step with this issue is to check with your service provider. Make a quick chat or call your service provider’s customer care executive and let them know the problem. They will prevent it from their end, and if the issue is from the provider’s side, they will let you know the same in that case, no further action from your side, and the problem will get sorted soon.

If the issue is not from their end, they will let you know the troubleshooting methods, and if none of them fixed the problem, then it might be an issue with your physical SIM card, and you need to proceed with the further steps.

Replace your SIM card with a new SIM card

Sometimes, the SIM card may get corrupted or damaged, failing the SIM card registration. So, if the above steps don’t fix the issue, the final step is to replace your SIM card.

To trouble shoot and to check whether the SIM card is working, you can insert the SIM card on another mobile. If the SIM is working fine on the other phone, then there won’t be any issue with the SIM, but it might be an issue with the mobile. If the SIM is not working on the other mobile, you can assume that the issue is with the SIM or the mobile network.

  1. Hi Vipin, I am having problems with texting picture messages on my Android. The carrier obviously is not interested in helping me as they hang up on me or just leave an opened line. I noticed last time that I was walked through their steps that my Mobile Network State is disconnected. I can’t figure out how to reconnect it. Do you have any ideas on this? They have said it’s my SIM card but no explanation of why. Thanks in advance!
