No(/poor(one bar)) Service - Wifi works - What to do?
I recently bought a second-hand iPhone 3GS 32GB Black. It's without an unlock so all simcards should work.
Nevertheless, no simcard works, the iPhone keeps saying 'No service' most of the time and occasionally I have one bar.
I tried different simcards. Didn't work.
I tried another iPhone 3GS with the same sim on the same locations and this one has perfect service.
I tried updating to the newest (4.3.5) firmware. Didn't work.
I tried a full reset. Didn't work.
I tried resetting the network configurations. Didn't work.
Could you guys please help me?
I've been searching the internet for hours and hours but no solution yet.
Is this a good question?
