Please read the following terms and conditions carefully. These terms and conditions govern the Promotion.
  1. The Promotion is open to new customers who purchase an International Sim tariff (“New Customer”), existing Pay As You Go customers who switch to an International Sim tariff (“Switching Customer”), and existing customers who renew their existing International Sim tariff (including O2 Unlimited customers) (“Existing Customer”).
  2. The Promotion will run between 8th October 2015 – 31st December 2015 (the “Promotion Period”). O2 reserves the right to extend or shorten the Promotion Period at any time. 
  3. Provided that you are a New Customer, a Switching Customer or an Existing Customer and you top up a minimum of £15 prior to the expiry of the Promotion Period, you will be entitled to 1GB extra UK data on top of your standard data allowance (the “Extra Allowance”).
  4. If you are a New Customer you will receive the Extra Allowance automatically when you top up.
  5. If you are an Existing Customer or a Switching Customer you will need to:
  • opt into the Promotion by texting “INTBONUS” to “2424” prior to the expiry of the Promotion Period; and
  • top up £15 or more within 30 days of opting in.
  1. After you have topped up (the “Activation Date”) the Extra Allowance will be applied to your first bundle allowance after the Activation Date.
  2. Any subsequent Extra Allowance will be applied on the monthly anniversary date of the Activation Date (the “Top Up Date”).
  3. You will receive a text message to notify you before the Extra Allowance is applied.
