Unfortunately, NO. Members cannot activate multiple SIMs onto the same account. There can only be one SIM active on your giffgaff account at a time. You’ll need to create a separate account for each SIM.
You can activate multiple SIMs on new accounts using the same email address and payment details, so managing them is easy.
The giffgaff app allows you to manage multiple accounts so that you can easily switch between, and manage them in one place.
Important: If you try to activate another SIM on an already active account, it performs a 'SIM swap', moving your number and plan/credit to the new SIM and deactivating the old one.
Note: When activating a new SIM, ensure you are logged out of any giffgaff account and then activate each new SIM on a new giffgaff account.
