You need at least 1GB saved in your Sky PIggybank to be able to use it, as it can only be rolled back or redeemed in whole GB values. E.g. 1GB not 0.45MB. And you'll need to wait until after your first bill period.
Got more than one plan? Before you roll back data, make sure you select the right mobile number/plan that you want to add it to, as changes can't be reversed.
At the end of the month (billing period):
- Any unused data from last month will roll over and show in your Sky Piggybank before midnight on your bill date.
- This includes data from your data plan allowance, any extra data bonus/data boost and any data Add Ons.
Unused data lasts for 3 years. There’s no limit to how much data you can save, but it expires after 3 years if you don’t use it.
- E.g. Data added in January 2017 will last until December 2019 but data added in February 2017 will last until January 2020.
