BFF time on 13 December = FREE data

What is your favourite day of the week for free data?

We organised a poll several weeks ago and Friday was the undisputed winner!

That's why we're making Friday the 13th your lucky day! Because we're treating our Based on you customers to free data all day long**. 

How does BASE For Free time work?

You are a Based on you customer

Your Based on you subscription adapts to your usage, because sometimes you can use a little extra. That is why we will surprise you with BASE For Free time every now and then. This means free mobile data OR call credit when you need them most. The mobile data or call credit you use that day will not be charged. No action is required on your part: as a Based on you customer, you will automatically receive your BFF time. For no special reason, as a token of our appreciation.

BASE For Free conditions: a Based on you subscription, a location in Belgium or the EU zone, normal usage**

We will keep you updated on our next BFF moments on our website and Facebook.

You are a BASE customer without a Based on you rate plan

If that is the case, now is the perfect time to switch. Besides the many advantages Based on you offers by adapting to your usage, it also gives you BFF. Switch now in the customer zone or the app.
