FAQs

To activate your SIM, you’ll need a credit/debit card, or a top-up voucher.

Once you’ve activated your SIM pop it into an unlocked phone and you’re ready to go.

Pop in your activation code and follow the quick, easy steps to activate your SIM. On the payment page, select voucher and enter your 16 digit voucher code.

Sure thing. We’d love to bring your old number to giffgaff. After you’ve activated your SIM, we’ll give you a link to transfer your old number. You’ll just need your PAC code from your previous network.

If you're already a member, swapping your SIM will let you use a different SIM if yours is the wrong size, missing or faulty. Enter the code from your new SIM and click "Activate your SIM". On the next screen, log in with your giffgaff member name or phone number.

No worries. You can enter your SIM serial number from the back of the card. It's between 11 and 19 digits.
