Switching To T-Mobile

You will need to contact your current mobile phone provider and request a PAC code/Port Authorisation Code. This will usually take approximately 2-3 days to arrive. When you have received your PAC code,  click here  to view the very latest online deals and special offers from T-Mobile .  Once you have found the deal you want from T-Mobile , when completing your order, submit your PAC code when requested into the approprite box on the ordering form.  T-Mobile will then provide you with a temporary number to use whilst your existing number is transferred over, which may take a few days.

Please note - that you should not cancel your contract with your existing provider until they have provided you with your PAC code, free of charge, and you have given this to your new mobile phone provider, T-Mobile. If you cancel before then your new service provider, T-Mobile may not be able to transfer your number across and you may also incur a connection fee.

Once you have received your T-Mobile Port Authorization Code (PAC code) simply choose the deal that best suits your usage requirements and order online - during the order process you will be asked to enter your T-Mobile PAC code.  Please note - that many of the best mobile phone deals are only available exclusively online.  View the latest best online deals from Vodafone, 3 Mobile, O2, Orange, Virgin Mobile , Carphone Warehouse, Phones4u and Dialaphone.  Plus, check out the latest mobile phone voucher codes too.  Visit our voucher code website www.voucherseeker.co.uk.

The process takes approximately 7 working days.  Once this process is complete your existing SIM will no longer work and you will be given a new SIM card by your new service provider.

You cannot 'port' your number if you have chosen a new phone on your same network.  Your current service provider will provide you with an upgrade.

You cannot 'port' your number if you have not completed your minimum contract term with your existing supplier.  Check your existing terms and conditions with your current service provider to establish when you can change networks.
