    There are a few questions that you need to figure out:

    1. Do you have o2 UK coverage in your area? If not, you will get no service
    2. Does the o2 sim work? i.e. there is no problem with the sim itself
    3. Do you know if the cellular antenna on the iPhone work? It could be a hardware problem with the phone
    4. Are you sure the iPhone is locked to o2 UK but not other gsm carrier? If it's locked by other carrier, you will get no service.

    Good luck
