At the moment you can redeem fan points when you add OVO Extras, OVO Roaming or add a top up. You'll need to have enough points to pay in full - sorry part payments with points aren't possible at the moment.
You can redeem 200 points at any one time and a maximum of 200 points every 30 days. You won't be able to use points in conjunction with any other promotional offer and sorry but you can't join points with other customers, transfer points or gift your points to someone else.
And pretty soon you'll be able to use your fan points for other things too.
