My Alcatel Flash 2 was working fine but suddenly out of nowhere when i opened the dialer/ Phone app it is displaying this error. I have faced this issue twice. As a course of action, i cleared the data and cache of both the phone and sim toolkit so that they will be reset but still the problem persists. In my first case of facing this problem i had to do a factory reset. So my question is why the problem got repeated again? I can't factory reset everytime. It's a waste of time and data. I am not doing factory reset again. Please fix my problem. Here is the screenshot.
As you can see after closing the phone app the sim selection notification should also go but this is staying like this in the notification until i force stop the phone app. Help!
