Does it restart without the SIM card?

[rainrose44]

um i didnt try that ..... i will try it now but what the sim has to do with that??

@rainrose44

The SIM has a LOT to do with that, if the SIM card its defective it will restart the phone. 

[rainrose44]

so if the sim card is the problem all i need to do is change it and everything will be good ???
