Once you have received your Giffgaff SIM card, you would need to take several measures before you can enjoy its excellent perks.

The very first step to activating your SIM card is by visiting Giffgaff’s activation web page using your desktop, laptop, mobile phone, or tablet.

Step 2 – Enter Your Activation Code

Afterward, you need to type in your unique 6-character activation code found with your SIM card.

However, you can also use your 13-digit serial number located at the back of your card. Sometimes, this serial number is 16 or 19 digits long before the “4Ggg4” key.

Step 3 – Register

The next step you should do is to register for an account.

All you need to do is type in your email address and make your unique username and password.

Step 4 – Choose A Monthly Plan

You would also need to choose a monthly plan that would satisfy your needs.

You can select from Giffgaff’s wide range of offers, but if you want an additional £5 credit, you must choose a plan equal to or greater than £10.

However, if you have already selected your monthly plan upon ordering your SIM card, you can move on to the next step.

Step 5 – Enter Your Payment Details

You can only activate your SIM card using your credit or debit card.

But in cases where you do not own a card, you can also use a top-up voucher.

Below are the essential steps needed for you to make your payments:


If you are using your credit or debit card, you need to put your card details on the necessary fields.

This information includes the following:

  • Bank card number
  • Expiration date
  • Name on the card
  • Security code
Top-Up Voucher

However, if you are using a top-up voucher, you need to select the voucher option from the payment page before entering your 16-digit code found on your voucher

Step 6 – Wait for A Confirmation Text

Once you have entered your payment details, your Giffgaff SIM card activation will automatically begin processing.

This procedure may take a few minutes. But in several instances, it may take up to 24 hours.

Nevertheless, you will know if your card has successfully been activated if you receive a confirmation message.

Step 7 – Check If Plan Is Active

After receiving Giffgaff’s confirmation text, visit the My Giffgaff page on your phone or laptop to check whether your plan is active.

You can also dial *100*7# to see how many minutes you have left on your monthly plan.

In several instances, you will also receive a message from Giffgaff if you want to transfer your old phone number to your newly activated Giffgaff SIM.

For this step, you would need your PAC code from your previous cellular network.
