Phone is dead but it says battery 100 percent

If your phone is dead. How are you reading that it is fully charged?

What is the make and model of your phone?

Plug your device in.  Reboot your phone.

This has nothing to do with Public Mobile service.  Search google for your phone model and the problem you are having.  That should help you find a fix.
