Can I also surf or call unlimited abroad?

Can you also surf or call unlimited abroad? You can. Up to 14 GB there are no additional costs for the EU.

Your usage within Belgium isn't included in this 14 GB: only what you use outside of Belgium is. If you use more, every MB used in the EU will be charged at € 0,004/MB. If you use over 20 GB during your bundle period, both within Belgium and abroad, you'll be able to continue surfing at a reduced speed of 512 kbps.

Outside the EU, the
normal roaming rates apply, and you can’t use your Unlimited data bundle.
