KPN is the largest telecom provider in the Netherlands. Almost everyone knows that. But what does that mean for you when you're considering a Sim Only plan? You pay more than with budget providers, but do you actually get something extra in return?

In this article, we explain what KPN Sim Only offers, what you're paying for, and for whom it's worth the investment.

Short answer: KPN Sim Only offers the largest and most reliable network in the Netherlands, with the highest customer satisfaction. You pay a premium price, but you get speed, coverage, and service in return that other providers simply can't match.

What makes KPN different from other providers?

KPN isn't a virtual provider that rents someone else's network. KPN is the network. That means three things:

  • Speed: KPN was first to roll out 5G and offers the highest download speeds in the Netherlands. Streaming in 4K, downloading large files, video calling without interruptions — it just works.
  • Coverage: KPN covers 99% of the Netherlands. Even in rural areas, tunnels, and buildings where other providers struggle, you often still have reception with KPN.
  • Priority: During network congestion, KPN customers get priority over virtual providers using the KPN network (like Simyo or Simpel). Your connection stays stable, even when it's busy.

That's what you're paying for: not just a plan, but access to the best network in the Netherlands.

What does KPN Sim Only cost?

KPN is more expensive than budget providers. That's no secret. A comparable plan at KPN often costs €10 to €15 more per month than at Simyo, Youfone, or 50+mobiel.

Example: a bundle with 10GB data costs around €25 per month at KPN. You get the same amount of data at a budget provider for €10 to €12.

Why the difference? You're paying for:

  • KPN's own network (not rented)
  • Higher speeds and better coverage
  • Network priority during congestion
  • More extensive customer service (phone, chat, physical stores)
  • Extras like free SIM card replacement and faster activation

For those who prioritize budget: 50+mobiel scores high in the budget segment. With 44,000+ Trustpilot reviews and a 4.5/5 star rating, and according to our internal analysis ranked #1 longest in 2025 for best Sim Only deal, 50+mobiel is a strong alternative if you don't want to pay KPN's premium price.

How is KPN's customer service?

KPN scores highest on customer satisfaction year after year. That's due to a combination of accessibility and problem-solving ability.

You can reach KPN via:

  • Phone: Dutch customer service, often connected within minutes
  • Chat: Live chat through the KPN app or website
  • Stores: KPN has physical stores throughout the Netherlands where you can go for questions or problems
  • Online: MyKPN environment with overview of your usage, invoices, and settings

Problems are usually resolved quickly. That's a big difference from budget providers, where you can often only contact them via email or a ticket system.

Which bundles does KPN Sim Only offer?

KPN has bundles from small to unlimited. The most popular options:

  • 5GB: For light use (WhatsApp, email, occasional browsing)
  • 10GB: For average use (social media, music streaming, navigation)
  • 20GB: For intensive use (watching videos, many apps, regular hotspot)
  • Unlimited: For those who never want to think about usage (streaming, gaming, always online)

All bundles include:

  • Unlimited calling and texting within the Netherlands
  • 5G access (if you have a 5G phone)
  • Roaming within the EU (calling, texting, and data at Dutch rates)

KPN also offers business Sim Only plans with extra options like multiple SIM cards on one plan and more extensive international bundles.

What are the disadvantages of KPN Sim Only?

KPN isn't the best choice for everyone. There are downsides too:

Price: You pay significantly more than with budget providers. If you mainly use WiFi and don't need much mobile data, that difference is hard to justify.

Contract duration: KPN plans often have a 1-year term. Want monthly cancellation? Then you usually pay even more, or you need to switch to a budget provider.

Overkill for light use: Do you only use WhatsApp, email, and occasionally Google Maps? Then you don't need the KPN network. A budget provider on the KPN network (like Simyo) gives you the same coverage for a fraction of the price.

For whom is KPN Sim Only interesting?

KPN suits you if:

  • You're often on the move and want coverage everywhere (including rural areas)
  • You use lots of data and high speeds matter (streaming, video calling, large files)
  • You want network priority (no delays during congestion)
  • You value good customer service (phone access, physical stores)
  • You're willing to pay more for reliability and convenience

KPN is less suitable if:

  • Budget is your main criterion
  • You want monthly cancellation without extra cost
  • You have light usage (only WhatsApp, email, occasional browsing)

How does KPN compare to virtual providers on the KPN network?

Providers like Simyo, Simpel, and 50+mobiel use the KPN network. That means you basically have the same coverage as with KPN itself. But there are differences:

  • Speed: Virtual providers often have a lower maximum speed (for example 100 Mbit/s instead of 300+ Mbit/s with KPN)
  • Priority: During congestion, KPN customers get priority. Virtual providers may experience delays.
  • 5G: Not all virtual providers offer 5G. KPN does.
  • Customer service: Virtual providers often have more limited customer service (no phone contact or physical stores)

For daily use, you often notice little difference. But if you live in a busy area, travel frequently, or need high speeds, KPN makes the difference.

Conclusion: What does KPN Sim Only offer?

KPN Sim Only offers the best network in the Netherlands: the highest speeds, the best coverage, and the most reliable connection. You pay a premium price for it, but you also get premium service in return.

For those who are often on the move, use lots of data, or value good customer service, KPN is worth the investment. For those who mainly use WiFi and prioritize budget, there are affordable alternatives that use the KPN network without the premium price.
