my phone went to bed with me...plugged her in, and woke up to a triangle with an explanation mark in the middle...now it says Invalid Sim....i havent done a thing yet to the phone, but what should i do?
Why don't you start by re-booting the phone, removing and re-inserting the SIM, etc.
If that fails to clear it up, get a new SIM from your carrier.
