sim not recognised

Installed avast with theft app - now the only sim I have used in the phone doesn’t seem to be recognised - warning/lock screen and won’t accept password - how to uninstall without passcode???

Hi,

try 0000 as the password if the password you put in can’t be recognized.

Hi there ~ no 0000 not working

Hi, is it root installation? Do you have OTA update or some custom ROM?
