Already a BASE customer?

You get the same discount when you take an additional monthly plan or upgrade your existing one. For example, suppose you already have a BASE 20... Then you'll pay just €21/month for a BASE 29!

Did you buy a smartphone in combination with your current monthly plan? Or are you doing an upgrade for which you'll pay less for your new monthly plan after the discount than you're paying today? Then, unfortunately, you won't benefit from this promotional offer when you upgrade your monthly plan.
