Contact Orange to request your "Port Authorisation Code" (PAC) at the same time you give your notice of leaving. The Orange customer support line for Pay Monthly customers is 07973 100 150 (or 150 from your mobile), and for Pay As You Go customers dial 07973 100 450 (or 450 from your mobile). Orange will then send out your PAC code by post within 2 working days.
Once you have received your Port Authorization Code from Orange, look for the best T-Mobile offer that is suited to you. Many of the best mobile phone deals are available exclusively online, directly from the network providers listed here.
Finally, provide your PAC code to your new T-Mobile mobile network operator who will then be able to port your existing phone number from Orange. They will tell you what day the transfer is due to take place (usually within 48 hours).
Important: Do NOT cancel your contract before switching, otherwise you might not be able to port over your number. Once you provide your new network provider with your PAC code, your old account will automatically be cancelled when the number is migrated over.
Note: Credit on a PAYG (Pay-As-You-Go) account cannot be transferred and any remaining credit will be lost after the switch over.
The first step is to join T-Mobile.
Once you have done that, ensure you have the following information ready:
You will be given a temporary TMobile phone number, so you can enjoy the benefits of T-Mobile as soon as you receive your SIM card. When you receive it, call T-Mobile Customer Services on 0845 4123123, or 150 from a T Mobile phone, to register and provide your PAC code.
Note: You may lose network service for a short period on the day of transfer. If this happens, turn your phone off and on occasionally, until you see the T-Mobile signal on your mobile phone screen. This will indicate that the transfer is complete.
