If you buy a Data Extra and your data cap is activated, your data cap will extend accordingly. For example, if your monthly allowance is 5GB and you buy a 500MB Data Extra, your data cap will increase from 5GB to 5.5GB.
However, if you buy a Data Extra while opted out of the data cap, it won’t switch your data cap back on – instead you’ll be able to carry on using data freely without any cap.
If your plan features an allowance of inclusive roaming data and your inclusive roaming data cap is switched off, buying a Data Extra will switch it back on. The new limit will include the extra data you’ve bought. That cap will then remain in place until you remove it again or add another Data Extra.
This doesn’t apply for:
- 1GB and 2GB data extras for roaming
- Your UK data cap
If your inclusive roaming data cap is switched on and you’ve reached the end of your allowance, when you buy a Data Extra it will re-set the cap, now including the extra data you’ve bought. If you use up all the data in your Data Extra, you’ll once again be capped.
