Could a faulty SIM card cause my android to spontaneously reboot My android (Sony Xperia 10a) spontaneously reboots on a 1m to 15m cycle.   I had a Nokia before and I think it rebooted more often than expected as well.  My Google contacts, a SIM and AT&amp;T are the only things I brought forward from one to the other so I suspect all three.

Does anyone know if a bad SIM can cause rebooting?
Perhaps it could but not in this case.  I'm going to go with faulty hardware and here's why.  I have tried the following:

Action.... Rationale


full reset ... installed too many
apps and corrupted OS? 
full reset and
reformat memory card ... corrupt file
system on mem card? 
full reset and
don't use a memory card ... defective
mem card? new sim card ... bad sim?
full reset + new google account ...
bad data in google account? 
full
reset + original google account but
do not activate any location
awareness ... suspect GPS issue


In each case I can get the phone to fail in 5-45 minutes and usually within 20m as long as I'm tranferring some data via 3g (youtube, downloads etc).

So, since I have swapped out everything except the physical phone hardware the problem must lay in the device itself.  Glad there's a manufacturer's warranty
