O2 Refresh lets you change phones whenever you want. It works by splitting your bill into two parts: a Phone Plan and an Airtime Plan. The Phone Plan is the cost of the phone and the Airtime Plan covers all your calls, texts and data. If you want to upgrade your phone, just pay off your Device Plan and you're free to choose your new device and tariff.Plus, if you decide to keep your phone once youâve paid it off, we'll only charge you for your Airtime Plan â so your monthly bill will go down.
