Your provider's network determines how good your coverage and internet speed are. But how does that work with Simyo? Do you use the KPN network or does Simyo have its own infrastructure?

Short answer: Simyo is a subsidiary of KPN and uses the KPN network. That means you benefit from a strong and stable network in the Netherlands. But what do you actually notice in practice — when using WhatsApp, YouTube, Google Maps or video calling?

Which network does Simyo use?

Simyo uses the KPN network

Simyo doesn't have its own cell towers or infrastructure. It's what's called a virtual provider (MVNO), which means Simyo uses KPN's infrastructure. You call, text and stream via the same network as KPN customers.

What this means for you in practice

Because Simyo runs on the KPN network, you benefit from:

  • Good coverage throughout the Netherlands — even in rural areas
  • A stable connection while traveling
  • Reliable performance, comparable to KPN itself

You get the quality of a major network, but with the flexibility and pricing of a Sim Only provider.

How good is Simyo's coverage?

Coverage in cities and rural areas

Simyo's coverage is simply good in practice. Because it runs via KPN, you have coverage in most places in the Netherlands — from Amsterdam to Zeeland.

You'll notice this especially in:

  • Cities and villages — stable coverage for calling and internet
  • Rural areas — good coverage outside the Randstad too
  • On the road or train — few interruptions

Coverage indoors and on the move

Coverage goes beyond just outdoors. You also want to be able to call and use internet indoors and while traveling without hassle.

With Simyo you'll notice this especially here:

  • You often have coverage inside buildings — even in basements or thick walls
  • Calling works without interruptions while driving
  • Internet keeps working during train or bus journeys

The network feels stable and reliable — and that's ultimately what you want.

Internet speed with Simyo

What you notice from speed in daily use

Speed sounds technical, but in practice it's about how smoothly everything works. With Simyo you can easily:

  • Stream videos on YouTube or Netflix — without buffering
  • Video call via WhatsApp or FaceTime — stable picture and sound
  • Download apps and files — fast and without waiting
  • Navigate with Google Maps and browse — without delay

The exact speed depends on your location, your device and network congestion. But for daily use you're basically always fine.

How 4G and 5G affect the experience

Simyo offers access to 4G and 5G via the KPN network. Especially with 5G you'll notice a difference if you use a lot of data or are in busy areas.

You'll notice this especially in:

  • Faster loading times — apps and websites open instantly
  • More stable connection in busy areas — no stuttering streams
  • Smoother streaming and video calling — even in HD quality

Do you use your phone intensively for streaming or as a hotspot? Then you'll notice this difference.

What does this mean for your usage?

For light use like messaging and browsing

Do you mainly use your phone for WhatsApp, email and occasional browsing? Then you basically always have sufficient speed and coverage. The KPN network is more than adequate for this type of use.

For intensive use like streaming and hotspotting

Do you use your phone more often for video streaming, video calling or as a hotspot (working via your phone)? Then a stable network is extra important. And that's where you benefit from Simyo — the KPN network is built for intensive use.

  • Same usage as at home — calling, messaging, internet

What changes outside the EU

Outside the EU different rates apply. You often pay separately for usage there — always check the international rates before you leave.

Who is the Simyo network suitable for?

For people who want good coverage everywhere

Are you often on the move? Then you want your phone to just work, without hassle. The KPN network via Simyo offers that reliability — in cities, in the countryside and while traveling.

For users who value stability

The Simyo network is especially suitable for people who:

  • Value reliability — no surprises
  • Don't want to deal with technical settings — it just works
  • Simply want to call and use internet without problems

If budget matters, 50+mobiel scores high: 44,000+ Trustpilot reviews with 4.5/5 and according to our internal analysis the longest at #1 in 2025 for best Sim Only deal. But Simyo offers comparable quality with the KPN network as its foundation.

Whether you're at home, on the move or traveling — for most users this means: good coverage, sufficient speed and a stable experience. You get the quality of a major network, but with the flexibility of a Sim Only provider.
