If you don't top up, or add a Bolt On at least once in any six month period, your mobile will be disconnected and you'll lose any credit on your account. If you want to be reconnected you'll be given a new mobile number.

You can switch at any time and any credit you have will transfer over with your new tariff.

If you transfer to another Pay As You Go tariff from Classic Pay As You Go, and have an International Bolt On or International One Off Bolt On, you‘ll lose this Bolt On.

If you are on a non-Classic Pay As You Go tariff and switch to Classic Pay As You Go, you could lose a non-transferable Bolt On.

You can add Bolt Ons whenever you like by visiting My O2 and selecting My tariff and Bolt Ons, or by calling 2202, free from your mobile.
