Hello, I can have unlocked iPhone 5 for good money, but there is a problem that device has no service. PIN is accepted, than iPhone is searching for signal and after a while NO SERVICE. This is sellers description. I have no chance to try my SIM card, or sth like that. I know that it could be only problem with SIM card or is neccessary to RESET NETWORK SETTINGS, on/off Airplane mode and so on.. If it will be HW issue, could a problem be with sth another than Antenna? I have one iPhone 5, that is iCloud locked, so I can change antenna from this.
Thanks

Thanks
