With the old €15 BASE monthly plan you also benefit from Data Jump, but in a slightly different way. If you have an amount left at the end of the month, it's carried over.
You have the old €15 BASE monthly plan and at the end of the month you have only used €10.
- That means you still have €5 of your monthly amount left over. This amount is automatically carried over to the next month, so you start the new billing period with €20.
- First you use the remaining €5. Only then do you start using the new monthly amount.
Good to know: The remaining amount from a particular month can only be carried over one time. This means that if the amount remaining from last month hasn't been used up at the end of this month, you can't carry it over again.
