Porting your mobile number from T-Mobile to Sky Mobile

Leaving T-Mobile

How to switch from T-Mobile and transfer my number to Sky 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 PAC code by text and begin the porting process.

  • T-Mobile will provide your Porting Authorisation Code (PAC) either by SMS text message, via email, or over the phone if you contact them.
  • 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.

While you wait for your Port Authorization Code from T-Mobile, get the best Sky Mobile offer for you. Many of these exclusive mobile phone deals are only available online, directly from the network providers listed here.

Got your PAC code from T-Mobile?

Provide your PAC code from T-Mobile to Sky Mobile online 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 may lose your existing phone number and be unable to port it over. Once you provide your new network provider with your PAC code, your old account will be clsoed automatically when the 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 before porting your number.

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

First get your Sky Mobile package with your new SIM card.

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

  • Your original mobile phone number you want to keep.
  • The Porting Authorisation 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 Sky Mobile SIM card.
  • You may also need the new SIM card number found on the back.

Ensure your Sky Mobile SIM is activate before transfering your existing number. Once your SIM is activated, you can request the transfer from within your online account or by calling Sky customer services on 03300 413 000.

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 Sky Mobile signal on your mobile phone screen. This will indicate that the transfer is complete, and you can now use your existing phone number in your new mobile network provider.
