Before you begin, you'll need an unactivated giffgaff SIM. If you have a spare one at home and you wish to check that it is suitable for a SIM Swap, simply pop the SIM into your handset. You should be able to see a giffgaff / O2 signal in any unlocked / O2 locked device.
Next, dial*100# and it should return anon-activestatus message. If any other message is shown then the SIM is not suitable for a SIM Swap. Please order a new SIM using one of the methods below:
SIM Swap is the process of replacing your existing SIM with a new SIM and moving your existing number, allowances etc. to a new SIM.
Please note: You can use any unactivated SIM card to perform a SIM Swap. SIM Swap only available between 4.30am and 9.30am.
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.
Login and go to the Replace your SIM section of your account and click on Activate your SIM.
Enter the 6 digit activation code of the new SIM card and click "Activate your SIM"
This is where SIM Swap starts. You'll be told that you are about to carry out a SIM swap. You can make sure that the new SSN codes match the new SIM (it is the code on the back of the sim card). All good? Then, press "Yes, I want to replace my SIM"
You will then be asked if you are sure you want to do a sim swap. Click "Yes I'm sure" to complete the process.
Once you have pressed "Yes I'm sure", you will be taken back to My giffgaff where your dashboard will look like this. Once the SIM is fully activated your phone number, 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.
Please note: As soon as you have ordered a replacement SIM using the Lost & Stolen procedure 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.
Once started, SIM Swap is non-reversible and your old SIM will be deactivated and rendered useless. If you did not back up your contact details from the old SIM it will be impossible to retrieve them after SIM Swap.
SIMs used in SIM Swap 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 / 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 won't lose any allowances or airtime credit.
There are three types of SIM cards that have been issued from giffgaff. All are suitable for SIM Swap.
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.
Please note: You can use any 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.
