unlocking with Tesco Mobile
Unlocking a phone from Tesco Mobile costs anything from £0 to £20. How much will depend on how long you've been with them and whether you've seen out the terms of your contract.
Tesco will unlock your Pay-As-You-Go phone for free 12 months after the date you bought it. If you've honoured your contract commitments you can also unlock your phone for free. Otherwise you will have to pay £20 (inclusive of VAT). Also refer to their terms of service for more information. To obtain your 'unlatching' code (as they call it), call Customer Care on 0845 301 4455 (or 4455 from your Tesco Mobile) for further information on the qualifying period, applicable conditions and charges.
