V200 "No service"

My friend have a Samsung V200, and she tried to connect the phone to a PC using the supplied cables and the EasyGPRS software that comes with the phone. The next day, while opening the phone, it starts to search the network and now it has no signal and on its LCD it says NO SERVICE. Did the connection to the PC has anything to do with it? Can someone help us? Thanks in advance. :rolleyes:

change the network selection and check.

Thanks n Regards
