I am in the US and have bought an AT&T SIM for my iPhone 4.
I am a Virgin SIM only monthly customer.
I am getitng a message that says 'No service' when I put a new SIM in.
Do I need to get my phone unlocked and if so how? I thought it was already unlocked...
It should be unlocked.
Have you done a hard reset of the phone? It might be locked to the UK GSM frequencies. The USA uses a different pair of frequencies.
Welcome to the community and thanks for posting.
I can see Gorf has already been helping you out which is great.
I was wondering did you manage to get this sorted?
