Is there a way to fix a tmobile mda if it is displaying "invalid or missing sim"?
I have a tmobile mda and one morning it displayed "invalid or missing sim" and cannot get past it. The phone is accessible as far as the main menu, etc. I have done a soft reset and hard reset on the phone but still is displaying the message. I have also cleared the contacts and used multiple sim cards to test the phone with (activated and not activated sims).
