Porting your mobile number from ASDA Mobile to giffgaff

Leaving ASDA Mobile

How to switch from ASDA Mobile & take your mobile number to giffgaff

Request your PAC (Port Authorisation Code) by contacting the ASDA Mobile Helpline on 2732 from your ASDA Mobile or 0800 079 2732 from any other phone.

  • ASDA Mobile will provide your Porting Authorisation Code (PAC) 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 ASDA Mobile account will remain active until your number has been ported over to the new network. After the transfer is complete, your ASDA Mobile account will be automatically closed.
  • ASDA 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

Many of the top mobile phone deals are available exclusively online, directly from the network providers listed here. So once you have received your Port Authorization Code from ASDA Mobile, get the best giffgaff offer suited to you.

Finally, provide your PAC code to your new giffgaff mobile network operator who will then be able to port your existing phone number from ASDA 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 automatically be closed once 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.

Joining giffgaff

How to switch to giffgaff & bring your ASDA Mobile number with you

The first step is to sign up with giffgaff to get 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 ASDA 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 giffgaff sim card.
  • You may also need the new SIM card number found on the back.

Make sure your giffgaff account and SIM have been activated. Then log in to your account and complete the transfer form to keep your old number. A Giff gaff customer support agent will then get back to you with your transfer date. Replies can be found in your giffgaff account message box.

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 giffgaff 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.
