Phone wont recognize any sim card and spams error messages

Android Central Question

Recently I made a call and after finishing my sim card icons became empty and my phone started spamming
"Unfortunately process has stopped" and since then my phone won't recognize my sim cards at all and there would always be a permanent notification icon (sim card with a ! in the middle) and the message keeps on appearing and disappearing literally every 0.01 millisecond

Why is that happening and how do I fix it?

I tried many things like
-data wiping the phone app
-restarting the phone
-reinserting my sim cards
None have worked

Welcome to Android Central.

When you say data wiping the phone, do you mean you factory reset the device?

Ignoring the data wipe statement, have you tried resetting your network settings? On my Samsung this is in the same location as factory resetting the device.

Have you reached out to your provider? They should be able to help with SIM and connection issues.

Things you can try:

-force a restart by either holding the power button until it resets or holding volume down and power or volume up and power until it restarts depending on what phone you have. Normal restart and force restart are different.

-use wifi and check for a system update.

-put the phone in safe mode and see if it still happens. Could be an app you downloaded.

-try clearing the cache on the phone app. As well as clearing the cache on the sim toolkit app. Then restart phone.

-make sure the time and date are correct by going to settings and disabling/enabling automatic date and time.

-enter recovery mode and clear cache partition.

-reset app preferences in system settings.

-reset network in system settings.

-factory reset or new sim card.

Welcome to Android Central! Which phone do you have? Is it really old?

I wouldn't say the phone is "spamming" you. Something essential in the system has either failed or become corrupt, which is why you're getting this error message. Probably the simplest thing to do right now would be to go to your carrier store and ask for a replacement SIM.
