What is a NUC Code?

NUCs, or network unlocking codes, are used to unlock a mobile phone from its original network (i.e. Vodafone, Orange, T-Mobile, O2, Virgin Mobile or 3). When mobile phones are purchased the phone isusually locked to the network whose service you originally signed up to. This prevents SIM cards from other networks being used on the mobile phone. Once a network unlocing code (NUC code) is used on the mobile phone, it is possible to use SIM cards from other networks in that phone, allowing users to swap and change network providers at will.

What information will I need to retrieve my NUC code?

You will need your IMEI number, the network your phone is currently locked to, the mobile phone make and model and your mobile phone number.
