Help Rebooting Nexus S

Hi,

I had this problem with my previous ZTE Blade - the phone randomly rebooted (say twice a day), usually when the phone wasnt doing anything difficult (like placing icons on the desktop etc.) - when under stress (like stability test, fast discharge or angry birds), it was OK. This was strange.

So I decided to give it back and purchase Nexus S instead. It came yesterday and did exactly the same - angry birds ok, update ok, bud then I was just scroling through screens and it rebooted itself. Right after that a stability test test ran OK all the night. Weird.

Im not sure if the phone asks you for PIN number for the SIM card after this kind of reboot but I believe it does - and during this restart, it did not. So I started to blame the SIM card, which is old and scratched. Today, I charged the phone full, inserted my other sim from another carrier (first was O2, the second is Vodafone - much younger, less used) and am going to test.

Is it possible those exactly same reboots on two different phones are caused by the SIM or maybe the operator?
 
Well it could be the old SIM or the phone. Or both. Hopefully all will go well for you now. I've never had any issues with my Nexus S and I always get a new SIM with each new phone I buy.
 
Well you see here ,we have a problem ,but don't panic ! :)


You have to change your carrier's sim card with a new gen one [any sim from the past 4-5 months will do] ,WHY ? Well.. because some phones fry your sim card if it's too old ,some reboot ,some lose signal ,and some don't even recognize it :D ...so go and change your antique sim card :P

can you keep your old phone number when getting a new sim? and how can you tell if a sim is a new one or a old one?
 
Well you can ask at the store to get a newer sim card and explain why ...and yes ,you will keep your same number ! BE SURE TO BACKUP ANY SIM RELATED CONTACTS BEFORE :)
