Question about Sony Ericsson K770i Purple 3G Camera mobile+256mb Cellular Phone
Try sim with other fone on same network, if prob cont. with other fone then contact your network.
If ok with other fone try selecting Menu>Settings>Press Navigation key right to find Connectivity>Scroll to Mobile networks>Select GSM/3G networks>Turn phone off>On.
If this doesn't work you will need to take your fone to a service center.
