Get Sky Mobile PAC code to keep number & switch to Mozillion network

Keep my Sky Mobile number

How do I get a PAC code from Sky Mobile & transfer my number to Mozillion?

Sky Mobile customer services can be contacted by telephoning 03300 412 524 to cancel your account and request your Port Authorisation Code (PAC). Your Sky Mobile will remain active until your number has been ported over to your new network. Once the transfer is complete, your account will then be automatically closed.

If you wish to use the 'text-to-switch' service, simply send the SMS text PAC to 65075 free from your Sky Mobile SIM to get your Sky Mobile PAC code by text message and begin the porting process.
Alternatively, you can text STAC to 75075 if you want to switch and get a new Mozillion number instead of keeping and transferring your Sky Mobile number.

  • Sky Mobile will provide your PAC (Porting Authorisation Code) either by SMS text message, email, over the phone if you contact them directly, or through an online Sky Mobile login.
  • 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 Sky Mobile account will remain active until your number has been ported over to your new Mozillion network. After the transfer is complete, your old Sky Mobile account will be automatically closed.

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

Got your Sky Mobile PAC code?

Provide your PAC code from Sky Mobile to Mozillion who will then be able to port your existing Sky 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 Mozillion your Sky Mobile PAC code, your old Sky Mobile billing account will be closed automatically when your mobile phone number is successfully ported over.

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

Transfer my number to Mozillion

How to switch to Mozillion and keep my Sky Mobile number?

First get your Mozillion deal and activate your new SIM card.

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

  • Your old Sky Mobile mobile phone number that you want to keep.
  • The Sky Mobile PAC (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 Mozillion SIM card activation.
  • You may also need the new Mozillion SIM card serial number found on the back as an additional security check.

You will be asked during the ordering process if you want to keep your old number and supply the PAC code from your previous mobile network provider. If you decide to transfer your mobile number later instead, you can contact the Mozillion customer support team by sending an email to help@mozillion.com or calling 020 4516 3885.

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 Mozillion 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.
