Data Rollover

Data Rollover If you find you haven’t used all your data one month, don’t worry. It won’t go to waste as we let you roll it over to the next month and will always get used first. With Data Rollover, you’ve got the flex to make your data work for you, in the quieter months and the busy ones.

Available on selected tariffs, your data will roll over for one month. If you don’t use your rolled-over data by the end of the billing month it’s rolled into, it’ll expire. If that happens, don’t worry, as you won’t have used any of your regular monthly allowance, which itself will then roll over.

Flexible tariffs

Picking the right tariff for your business isn’t always straightforward. Thankfully on O2, we’ve made our business data tariffs flexible so they can work around you. If you find you’re using your data faster or slower one month, you can flex your allowance up or down. You can change your tariff 30 days after your contract starts, then once every billing cycle.
