Not registered on network
Got an S4 here and it is not blocked. IMEI is checked and is on O2. With a sim card in it has no service (recognises sim and loads voice mail) and just says not registered on network.
things i've done
- factory reset / cache wipe etc
- messed around in network settings
- flashed a different ROM through Odin
i am thinking it maybe hardware or antenna or something? i am not sure as it gets full wifi signal.
Is this a good question?
