Data Banking allows you to save your included data and use it later when it suits you. Data that you don’t use in the month, will be saved in your Data Bank for when you need it the most. You can store up to 30GB^ of unused data on our small and xsmall plans and up to 100GB^ on all other plans.
Let’s say your mobile plan gets 35GB of data each month. You start the month with 35GB but at the end of the month you find you’ve only used 10GB in the month. Instead of losing the 25GB of unused data, it will stay in ‘the bank’ until you need it. You now have a total of 60GB of data to use (35GB for this month + 25GB of unused data from last month).
