Leaving T-Mobile

How to switch from T-Mobile & take your mobile number to Lebara Mobile

T-Mobile customer services can be contacted by either dialing 150 from a T-Mobile SIM, or 0207 362 0200 from another phone, to request your "Port Authorisation Code" (PAC) at the same time that you give your notice of leaving TMobile.

  • T-Mobile will provide your Port Authorisation Code (PAC number) either over the telephone, by SMS text message or via email.
  • A PAC code is valid for 30 days. If you don't use it within thirty days it will expire and you will need to request a new one.
  • Your T-Mobile account will remain active until your number has been ported over to the new network. After the transfer is complete, your T-Mobile account will be automatically closed.
  • T-Mobile must issue you with a PAC number within 2 working days of your request, or a reason for why it cannot be issued, in accordance with Ofcom's "General Conditions of Entitlement". http://ofcom.org.uk

Once you have received your Port Authorization Code from T-Mobile, look for the best Lebara 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 Lebara Mobile mobile network operator who will then be able to port your existing phone number from T-Mobile. 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 / Pre-Pay) account cannot be transferred and any remaining credit will be lost after the switch over.

How to switch to Lebara Mobile & bring your T-Mobile number with you

The first step, if you haven't already, is to sign up with Lebara Mobile.

Once you have done that, ensure you have the following information ready:

  • Your original mobile phone number you want to keep.
  • The Port Authorization Code (PAC) from your previous T-Mobile network.
  • The expiry date of the PAC number (valid for 30 days from the date of issue).
  • The temporary mobile number from your new Lebara Mobile sim card.

Call Lebara Mobile on 0870 075 5588 (5588 from your Lebara Mobile or +44 2070310791 from overseas). Let LebaraMobile know that you want to use your existing mobile number and give them your Porting Authorisation Code (PAC). As soon as the number you wish to keep is live on your new Lebara Mobile SIM card they will send you an SMS text message to let you know.

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 Lebara Mobile signal on your mobile phone screen. This will indicate that the transfer is complete.
