To obtain the £5 extra credit, you must select a monthly plan equal or greater to £10. Don’t forget that when you join giffgaff your goodybag is automatically set to recurring.

- Credit top-up - Monthly plans do not include premium or international calls, but you can add some credit to your balance in case the £5 free credit is not enough for you. We call it airtime credit and you can add it at any time. Visit the following link to know our international rates calling from the United Kingdom to any country in the world. Remember that this credit does not expire and you can use it later to purchase a goodybag.
