Get T-Mobile PAC code to keep my number & transfer to Lebara Mobile network

Keep my T-Mobile number

How to get a PAC code from T-Mobile & transfer my 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.

If you wish to use the 'text-to-switch' service, simply SMS text PAC to 65075 free from your T-Mobile SIM to get your T-Mobile PAC code by text message and begin the porting process.

  • T-Mobile will provide your PAC code (Porting Authorisation Code) either by SMS text message, via email, or over the phone if you contact them.
  • A PAC number 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 your new Lebara Mobile network. After the transfer is complete, your old T-Mobile account will be automatically closed.

While you wait to get your T-Mobile PAC code, find the best Lebara Mobile online offer for you. Many of these exclusive mobile phone deals are only available online, directly from the network providers listed here.

Got your T-Mobile PAC code?

Provide your PAC code from T-Mobile to Lebara Mobile who will then be able to port your existing T-Mobile number. They will tell you what day the transfer is due to take place (usually within 48 hours).

Important: Do NOT cancel your SIM only or mobile contract before switching, otherwise you may lose your current phone number and be unable to port it over. Once you give Lebara Mobile your T-Mobile PAC code, your old T-Mobile billing account will be closed automatically when your mobile phone number is successfully ported over.

Note: Credit on Pre-Pay / PAYG (Pay-As-You-Go) accounts cannot be transferred over and so any remaining credit balance will be lost after the switch is complete. If you have any credit left, one good option is to donate it to a charity by SMS text message before porting your number.

Transfer my number to Lebara Mobile

How to switch to Lebara Mobile and keep my T-Mobile number?

First get your Lebara Mobile package and activate your new SIM card.

Once you have done that, get the following information ready to follow the step-by-step instructions:

  • Your old T-Mobile mobile phone number that you want to keep.
  • The T-Mobile PAC code (Porting Authorization Code) from your previous 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 activation.
  • You may also need the new Lebara Mobile SIM card serial number found on the back as an additional security check.

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, and you can now use your old phone number in your new mobile network provider.
