Yes - OVO Time is different and separate to your data allowance.
For a start OVO Time is measured in hours and not GB. It's a completely separate allowance from your data allowance and it's available to anyone that signs up to OVO. Your OVO Time allowance is there so that you can enjoy sport, radio and entertainment on OVOPlay (that's our app) without using up your data allowance.
Your data allowance is a monthly allocation of data measured in GB that you can use for general internet use - Facebook, email etc and it gets renewed every 30 days. If you're running low you can top up your data allowance anytime through the month.
The awesome thing about OVO Time is that its unlimited...on all our plans. And, since you've got OVO Time for sport, radio and entertainment you'll find that with OVO, your data allowance goes even further.
