How do I redeem my O2 Airtime rewards?
You can do this via the mobile application or via the website. You may only redeem airtime rewards (Airtime Rewards) listed in the Rewards section of the Application. You can select any credit package or bundle package available at that time for which you have accumulated sufficient balance for redemption.
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
