Does KPN offer a truly unlimited data bundle, and what does 'unlimited' actually mean — including abroad? Below you'll find how it works, including the concrete limits during roaming.

Does KPN offer an unlimited data bundle?

Yes. KPN has four Unlimited data bundles: Unlimited50 (€28 per month), Unlimited400 (€33.50 per month), SuperUnlimited (€35.50 per month), and SuperUnlimited+ (€40 per month). All four include unlimited calling and texting as standard.

What does 'unlimited' mean exactly in the Netherlands?

If you use more than 20 GB in a single day in the Netherlands, an additional 2 GB top-up purchase is required via the KPN app or by text before you can continue browsing at high speed. KPN doesn't state a fixed price for this 2 GB top-up on its own website — check this directly with KPN if in doubt. For most users, even heavy users, this daily cap isn't likely to be an issue in practice.

EU roaming: concrete data bundle limits per Unlimited plan

Traveling within the EU? Each Unlimited plan has its own data bundle limit for roaming: Unlimited50 offers 40 GB in the EU, Unlimited400 offers 50 GB, SuperUnlimited offers 75 GB, and SuperUnlimited+ offers 100 GB. Calling and texting remain unlimited within the EU, at no extra cost.

What happens if you exceed your EU data bundle?

If you go over your data bundle limit in the EU, your speed is throttled to 64 Kbit/s download and 32 Kbit/s upload. So you won't be charged extra automatically, but high-speed browsing stops until your new bundle period starts or you're back in the Netherlands.

Usage outside the EU

Different rules apply outside the EU. You'll need a separate 'Buitenlandbundel' (foreign bundle), with a spending cap of €121 per month for data. Once that amount is reached, internet access is blocked via KPN's 'Bescherming Internet Buitenland' (foreign internet protection), so you don't end up with an unexpectedly high bill.

With SuperUnlimited+, you also get 25 GB per month for use in a fixed list of countries outside the EU: the United States, Canada, Turkey, Morocco, Caribbean Netherlands, Suriname, India, South Africa, Brazil, and Albania.

Watch out for satellite connections

Even within European waters, a satellite connection (for example on board a ship) can cost up to €10 per MB. Turn off mobile data or switch to airplane mode while on board, unless you're certain you're connected to a regular land-based network.

Comparison with other sim-only providers

With concrete EU limits ranging from 40 to 100 GB depending on your Unlimited bundle, KPN offers upfront clarity about what to expect in the EU. Wondering how this compares to other providers? Always compare this before choosing, especially if you travel within the EU regularly.

Who is a KPN Unlimited bundle worth it for?

Travel often within the EU and want to know upfront where you stand on data? A KPN Unlimited plan is a good choice thanks to its concrete per-bundle limits.

Conclusion

KPN offers four Unlimited data bundles with unlimited calling, texting, and browsing in the Netherlands (with a daily fair-use cap of 20 GB). Within the EU, concrete data bundle limits apply, ranging from 40 to 100 GB per plan; go over that, and your speed is reduced rather than being charged extra. Outside the EU, you need a separate foreign bundle with a €121 monthly spending cap.
