SIM Swap allows you to transfer your giffgaff number to a brand new SIM card including existing goodybags/gigabags and airtime credit.

Here is a quick video that will guide you through all the steps.

Please Note: Effective from the 11th January 2017 any unactivated SIM can be used for a SIM Swap (It does not need to be less than 6 months old as shown within this video).

If you would rather read about it check out the section below:

More Information

SIM Swap is the process of replacing your existing SIM with a new SIM, moving your existing number etc to the new SIM.

Please note: Effective from the 11th January 2017 you can use any unactivated SIM card to perform a SIM Swap. The restrictions on SIM's being less than 6 months old has been lifted,  older SIM's can now be used.

Before you start, you'll need a giffgaff SIM to fit your phone which has never been activated. If you don't have an unactivated SIM, you can order a new SIM here. (NB. SIM Swap does not change your number. To do that see this article instead). 

If you have an old unactivated SIM card and wish to check that it is suitable for a SIM Swap, simply pop the SIM into your handset, All suitable unactivated SIM's will show a giffgaff / O2 signal, next dial *100# and it should return a "non active" status message. If any other message is shown then the SIM is not suitable for a SIM Swap. Please order a new SIM here and on receipt of your new SIM continue the process below.

To perform a SIM Swap:

  • Back-up any contacts, texts and other data saved on your current SIM to your phone memory or PC, as this cannot be transferred through SIM Swap.
  • Go to the Replace your SIM section of My giffgaff and click on 'Activate your SIM'.

If you have an active PAC code on your account then the link above will not work for you. Instead follow this link to cancel the PAC code and proceed from the point above.

  • Enter the 6 digit activation code of the new SIM card, and click 'Continue'.

  • This is where SIM Swap starts. It will ask you to confirm that you want to swap SIMs. (You'll need to double check the SIM Serial Numbers (SSN) to confirm you've logged into the correct account.)

  • After choosing "Yes, I want to replace my SIM" then "Yes, I'm sure", your old SIM will be deactivated and activation of the new SIM will begin. This may take anything from a few minutes to 24 hours - the 'norm' is around 30 minutes.

  • Once you have pressed 'Yes I'm sure' click the button to take you back to My giffgaff where your dashboard will look like this. Once the SIM is activated your goodybag/gigabag and airtime credit will show.

  • Put the new SIM into your device. Turn the device OFF/ON at 30 minute intervals until you get a signal and the SIM starts working.
  • You have completed SIM Swap! Enjoy.

I've lost my activation code, what do I do?

If you have lost the plastic card on which the activation code was printed then simply enter the 13, 16 or 19 digit SIM serial number instead.

The SIM Serial Number (SSN) is printed on your SIM card. Just look for the 13, 16 or 19 digit code located by the 3Ggg1 for 3G SIM cards or 4Ggg4 for 4G SIM cards.

If you have a Nano SIM then enter 894411 first followed by the 13 digit SSN found on your SIM.

When you lose your SIM card, you'll want to find the quickest solution to have your number back and SIM Swap looks like the best option.

It's only advised if you meet the two following conditions:

  • You don't need to bar your phone
  • You already have an unactivated giffgaff SIM of any age

If you don't match these two conditions, you should order a replacement SIM through the Lost & Stolen procedure.

Note: As soon as you have ordered a replacement SIM you will not be able to perform a SIM Swap.

If you try to perform a SIM Swap before receiving the replacement SIM it will fail, but your replacement SIM will be unaffected and you will still be able to activate the replacement SIM when it arrives.

  • You can only do a SIM Swap between 4:30am and 9:30pm.
  • Once started, SIM Swap is non-reversible (your old SIM will be deactivated and rendered useless).
  • SIM Swap does not change your mobile number
  • SIMs used in SIM Swaps do not qualify for, and will not generate any bonuses or payback points even when originally linked to an affiliate account
  • SIM Swap replaces your existing SIM with the new one. Once completed the new SIM will have your phone number and any existing airtime credit, goodybag or gigabag on it. All account information will remain the same.
  • You can perform a SIM Swap even if you don't have any data allowance or airtime credit available. All giffgaff pages are free rated so you you won't loose any allowances or airtime credit.

There are three types of SIM cards currently available from giffgaff

  • 3 in 1 SIM – Currently issued.
  • Standard/Micro SIM – No longer issued.
  • Nano SIM – No longer issued.

All of these SIMs are backwards compatible and can be used in any device using a 2G, 3G or 4G frequency.

Note: You can use a 3G SIM in any 4G device but it may take longer for your device to establish a 4G connection. This is normal and can be solved by doing a SIM swap to the latest 3 in 1 SIM.
