If you decide to remove or increase your spending cap, the change will happen straight away. If you don’t fancy waiting for your allowances to refresh at the end of the month, you’ll have buy a data add-on or choose to increase your spending cap. When this happens, you can’t use extra data – in fact, all extra charges outside your allowance will be blocked.

Expect a text from us when you reach 80% of your limit, another when you hit your spending cap.

Choose an amount (up to £100) to be your cap – the most you’ll spend on extra charges on your monthly mobile bills.

Or call 789 and ask us to arrange this for you.

If less rolled over than you expected, you probably have a special offer SIM (double or triple data maybe) and the most you can roll over on these is the SIM’s original, non-promotional amount of data. When you’ve used it all up, another text will tell you that your regular data allowance for the month has started.ĭon’t be surprised if your data rollover was rounded up – 23MB often become 25MB for example. A text will tell you how much data rollover you have or you can check your bill, next to your minutes, texts and data allowances.

Any leftover data you have at the end of the month’s automatically rolled to the next, giving you an extra month to enjoy it here in the UK or the EU.

But you can stop this happening, see: how to toggle off data completely (below). That’s why you can use these messenger apps and stay in touch, even when you’ve no more data – you’d only be charged for going over your allowance if Twitter, WhatsApp or Facebook Messenger update themselves in the background using extra data. These messages are data-free, even in the EU, says our monthly data usage policy (Voice and video calls are another story).

None of your data allowance’s used to send or receive pictures and videos, texts and voice notes on Facebook Messenger, Twitter or Whatsapp.
