Data Jump

Generation We Got This don't let their friends down. And certainly not their data.

What are the advantages of data jump?

  • All data that is leftover will be carried over to the next month.
  • Data Jump is always included in all our monthly plans.
  • Plus, every month, transferring data is totally automatic! You don't need to do anything, cool!
Discover Data jump in the My BASE app

How do I see that? In the My BASE app you see at a glance how much data you carried over. Just like that!

The best mobile plan, with lots of extras!
