KPN Sim Only: plans, quality & review

KPN is the largest telecom provider in the Netherlands — and you notice it. Own network, widest coverage, 5G standard on every plan. But you also pay more than with budget providers. What exactly do you get for that premium price? And for whom is KPN the best choice?

Short answer: KPN offers the highest network quality in the Netherlands with its own infrastructure and full 5G coverage. You pay more than with virtual providers, but get the best coverage, fastest connections and highest customer satisfaction. Suitable for those who value reliability over price.

What makes KPN different from other providers?

KPN is not a virtual provider that rents the network — KPN is the network. That means three concrete advantages:

Widest coverage: KPN covers 99% of the Netherlands, including rural areas where budget providers often have less reach
Own infrastructure: no dependency on other parties, direct control over maintenance and upgrades
5G standard: on all plans, without surcharge — even on the smallest subscriptions

You notice that difference especially on trains, in elevators, parking garages and rural areas. Where other providers sometimes have no signal, KPN usually does work.

KPN plans: what are the options?

KPN offers plans from 1GB to unlimited. The most popular options:

5GB: suitable for light use — WhatsApp, email, occasional browsing
10GB: for daily social media and streaming on wifi
20GB: enough for YouTube on the go and Google Maps
Unlimited: for those who watch Netflix on the train or use hotspot

All plans include unlimited calling and texting within the Netherlands. Calling abroad costs extra — check the rates per country in your MyKPN environment.

5G is included as standard. No separate surcharge, no separate subscription — your phone automatically switches when 5G is available in your area.

What does KPN Sim Only cost?

KPN is more expensive than budget providers. A 10GB plan costs around €20 per month with KPN, while you get the same amount of data for €10-12 with Simyo or Simpel.

Why that difference? You pay for:

The own network with better coverage
Higher speeds (up to 1000 Mbps on 5G, budget providers often sit at 100-300 Mbps)
Dutch customer service that you can reach by phone
Extras like WiFi Calling and VoLTE (calling via 4G/5G for better call quality)

For those who value budget: 50+mobiel scores high in our research — 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. That's a different choice than KPN, but relevant if price weighs heavier than premium network.

How is KPN's customer service?

KPN has Dutch customer service that you can reach by phone, chat and email. Opening hours are extensive: weekdays until 9 PM, weekends until 6 PM.

In independent customer satisfaction surveys, KPN consistently scores highest of all Dutch telecom providers. That doesn't mean there are never problems, but it does mean most customers are satisfied with how KPN responds.

You arrange most things via the MyKPN app: check usage, adjust plan, view invoices. The app is clear and works stably — no login problems or slow loading times like with some budget providers.

5G at KPN: what does that mean in practice?

5G is faster than 4G, but you really notice the difference only with large downloads or video streaming in high quality. Concrete examples:

Netflix in 4K: loads immediately, no buffering
Google Maps: maps load faster, especially in busy areas
Downloading large files: a 2GB movie takes 20 seconds instead of 3 minutes

5G only works if your phone supports it and if you're in an area with 5G coverage. KPN now covers 80% of the Netherlands with 5G, especially in cities and along highways. In rural areas you fall back to 4G — that works fine, just slightly slower.

Note: 5G uses more battery life. If your phone is old or your battery drains quickly, you can disable 5G in your settings. You then keep 4G speed — sufficient for most apps.

For whom is KPN Sim Only interesting?

KPN suits you if:

You often visit areas where other providers have poor reception (trains, rural areas, parking garages)
You value reliability more than the lowest price
You call a lot and want good call quality (VoLTE, WiFi Calling)
You need fast internet for work or study — think video calling, uploading large files

KPN is less interesting if:

You're mostly on wifi and use little mobile internet
Your budget is maximum €15 per month
You live in a city where all providers have good coverage

In that last case, budget providers like Simyo (on the KPN network) or Youfone often offer sufficient quality for less money.

How does KPN compare with budget providers on the same network?

Simyo and Simpel also use the KPN network, but with limitations:

Lower speed: often limited to 100-300 Mbps, KPN itself offers up to 1000 Mbps
No priority: during busy times (festivals, stations) KPN customers get priority — budget customers notice delays
More limited customer service: often only chat or email, no phone support

For daily use (WhatsApp, social media, YouTube) you notice little difference. For intensive use (4K streaming, large uploads, video calling in busy areas) KPN is noticeably better.

Conclusion: KPN Sim Only — plans, quality and review?

KPN offers the best network quality in the Netherlands: own infrastructure, widest coverage, 5G standard, highest speeds. You pay more than with budget providers, but get reliability, better customer service and priority during busy times.

For those who value reliability and speed — especially in rural areas or with intensive use — KPN is the best choice. For those who are mostly on wifi and value budget, virtual providers on the same network often offer sufficient quality for less money.
