What is SIM Swap ?

SIM Swap allows you to transfer your giffgaff number to a brand new SIM card (including existing goodybags and credits)





How does SIM Swap work?

 Back to top


SIM Swap is the operation of replacing your existing SIM with a new SIM card. Before you start, you need another SIM, which has never been activated and is less than 6 months old. If you don't have an unactivated SIM at hand, you can order a new SIM of any size here.


Here is the method to perform a SIM Swap. 


  1. Back-up all your contacts and texts saved on your SIM to your phone memory, as these data cannot be transfered through SIM Swap.
  2. Log out of your giffgaff account, and click "Activate SIM" on the home page.
  3. Enter the Activation code of the New SIM card.
  4. When on the account registration page, instead of registering, log in with the link in the "already registered?" section.


This is where SIM Swap starts. It will confirm that you want to swap SIMs. (You need to double check the serial numbers, just in case.)


5. After choosing "Yes" each time you are asked, your old SIM will be deactivated, and you will lose signal.

6. Put the new SIM in your phone, and it  takes around to 10 minutes  for the SIM to become active.


The best thing is to leave the phone turned off with the new SIM in for 10 minutes, then turn it on and off until you get signal.


7. You have completed SIM Swap! Enjoy.

Can I use SIM Swap to replace my lost / stolen 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 road. It is advisable only if you meet the two following conditions:


  1. You don't need to bar your phone
  2. You already have an unactivated giffgaff sim handy that is less than 6 months old

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