Perhaps the phone was reported lost/ stolen by the previous owner... if that is the case, the phone would lock, and not be able to work

Limited Service ???

what has happened is that the original owner has reported it to O2 and they have applied an IMEI bar to the handset that will be circulated to all uk networks. So unfortunately the phone is now useless! Dont bother spending money trying to unlock as you would be wasting your money once all the networks know. It probably worked for a while because the owner didnt report it straight away. Shame, not a bad phone!

turn off the phone
2. take out the battery and sim and put wrong network SIM and insert a half of it,
so it won't ask for network password and shows "Insert SIM" message.
