You will need to do a sim swap. Members can do a sim swap to transfer their number, account details, goodybag or credit etc from one sim to another.
Order a new Nano Sim from your Spread Giffgaff page or if you have a spare sim, do a sim swap. All Giffgaff sims are now dual and hybrid sims that contain a micro sim which pops out. Once the sim swap is complete; your mobile number, account details, goodybag or credit will be transferred over to the new sim.
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.

You can now activate a new sim if you loose one or it is damaged, or you need a micro or nano sim, by doing a sim swap.
Log out of gg, then click activate a sim, enter the 6 digit code, then select i have a gg account, then click sim swap. All your account details, credit and goodybags and number will be swapped to the new sim.
Please note, that sim swaps stop between 10 pm and around 6am.
