Hey, Ive had my LG KP501 for a couple of months now, and a few days ago it started coming up with "Sim card removed. Turn on after inserting sim" Just randomly, and then shutting down. Now it's doing several times a day, and often when I turn it on again, it flashes the message and shuts down again.

The only thing Ive found is it seems to do it less when on charge.

I have no idea what to try, any help is appreciated.
