In the image below, you can see that we have entered our Activation Code (5PKJ46) in the "Activate your SIM" button tab.

You can select a monthly plan (Goodybag) or you can just top up and have airtime / PAYG credit. You will be able to exchange the credit for a goodybag if you decide to do that.
You can use a credit / debit card, or a voucher.
If you have chosen a Goodybag deal, you have the option to renew the same Goodybag every month or to change it from "My giffgaff" on the official Giffgaff website. If you have chosen credit value, you can choose the auto top-up option.
The following credit / debit cards are accepted: Visa credit / debit (including Electron), MasterCard credit / debit (including Switch). Giffgaff doesn't accept payments with American Express or Diners Club. If you don't have another card, you will have to buy a top-up voucher.
Click on the "Voucher" option and enter your Voucher code numbers and personal data.
If the goodybag deal you have chosen is more expensive than the value of the voucher, your voucher will automatically become credit. If the goodybag is cheaper than the value of the "voucher", the remaining credit will be available as airtime credit.
After activating your giffgaff SIM card, you can buy a monthly goodybag with your coupon using the 43430 Top-up service. Otherwise, if you redeem it on the Internet, it will automatically become airtime credit.
You can then choose to exchange your credit for a goodybag.
