For some time now I have noticed a message appearing on my phone screen : refreshing SIM data.
This is very annoying and happen many times a day. I have Galaxy Note 10. Is it sim card broken or so?
How to fix it?
I’m waiting for Android 11 on Samsung A series.
There are various suggestions on Android forums.
Did the problem start after the update?
Have you checked your network connection settings?
You might try resetting the network connection and temporarily lowering from LTE/4G, down to 3G....then wait!...
This approach used to work for older mobiles for general connection problems when the signal was weak.
