Activating your giffgaff SIM card

When you receive your new giffgaff SIM card, you have to activate it to be able to use it. This tutorial will guide you, step-by-step, through the details to activate your giffgaff SIM.

Let's do it now

Follow these guides to activate your giffgaff SIM card


  • A giffgaff SIM card, if required order one on this page.
  • A payment method.

You will be able to test the signal strength before spending any money by inserting the SIM in your unlocked phone, however, payment is required to activate your giffgaff SIM card. You can make the payment by credit or debit card, or visit your local shop and get a giffgaff top-up voucher. We also accept O2 top-up vouchers - as giffgaff runs on the O2 network.

Minimum payment activation amount
  • If activating your SIM by topping up credit only, the minimum payment is £10.
  • If activating a SIM by the direct purchase of a goodybag, the minimum payment is £6 (if you use a debit card/ credit card) or £10 if you are using a voucher. This applies both to "referral" or "free SIMs".
If you order your giffgaff SIM card on our website, you will get £5 free credit bonus after activation.

Before you get started, make sure that your phone is unlocked and that you have coverage where you are.

Start by inserting the SIM card into your phone:

 See a signal? Great, you can now activate your SIM card.

  • It could be due to your mobile phone being locked to your previous provider. Do not worry, we have a helpful guide which gives you advice on how to unlock your phone in our unlockapedia section.
  • If your iPhone has been previously unlocked, you may have to synchronize with iTunes to complete the unlock.
  • If your mobile phone is unlocked, you may want to check the coverage in your area.
  • In case your giffgaff SIM is damaged, try inserting the SIM card into another mobile phone to check if there is a data connection symbol or a signal bar. Now dial * 100 #, if your phone does not show you any message on the screen, then you must order another giffgaff SIM card.
How to activate your giffgaff SIM

01On the home page of the official Giffgaff website, click on the "Activate your SIM" button to begin the activation process.

02Enter the activation code, consisting of 6 digits that you will find on the plastic card that contains your giffgaff SIM card, as you can see in the image below. In case you have lost this code, you have to use the 13 or 19 digit code printed on the SIM card itself (just before 3Ggg1 or 4Ggg4).

03Register or login. If you still do not have a Giffgaff account, you must create one now. With your Giffgaff account, you can manage your Giffgaff services and participate in the community. The username you choose can not be modified again.

04Select your product. You can select a monthly plan (a 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.

05Select your payment method. You can use a credit or debit card, or a voucher.

06Personal details. Enter the correct details of the person who will be using the SIM.

07Press the 'Activate my SIM' button and Yay! You're activated. A confirmation email will be sent to you.

When you have completed the entire activation process, your Giffgaff SIM card should be activated within 30 minutes to 24 hours. You'll then see the "Congratulations. You made it!" screen to confirm it. You'll then be invited to use the Setup Wizard. This last step is very important as it is used to make sure your phone settings are correct, so you'll be able to use the Internet and MMS.

Purchasing with a credit/debit card
  • 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.
Purchasing with a voucher
  • When you go through the activation process, you can buy a goodybag with your voucher.
  • 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.
