I don't know what to do I went on my cell this morning...it said device locked because SIM card can't be detected! Nothing was changed or buttered with! It gives me 2 options enter a password which is only numbers no letters just numbers or make an emergency call! I know its not my SIM because I can hit make emergency call and hit my back button instead of the call button and it allows me to go on my screen and through my phone but only for about 20 seconds then it goes back to lock screen... I need my cell phone so bad.. I don't know what to do or where to go.. I tried to access it from another place but it then says device not added that I have no devices..! What is happening?
