unlocking with T-Mobile
T-Mobile charge a flat fee of £20.42 for unlocking phones. This applies to both pay monthly and pay as you go customers and can take up to 10 days to unlock.
Both customers will need to be activated on the service for six months before they can unlock their phones with T-Mobile. Pay monthly customers must have an account balance of zero - everything should be paid and up-to-date before requesting an unlock.
