A Sim Only subscription from Simyo is known for flexibility, clear pricing and a reliable network. But does it suit you? More and more people in the Netherlands are choosing Sim Only instead of a subscription with a device — according to research by the Dutch Consumer & Market Authority, consumers often save structurally on their monthly costs this way.

In this article, we explain how Simyo works, what the benefits are and when it's a smart choice.

What is a Simyo Sim Only subscription?

A Sim Only subscription simply means: you only pay for your bundle (data, calls and texts), without a device.

With Simyo, you choose:

  • How much data you need
  • How many call minutes you use
  • How long your contract runs

This makes it flexible and often cheaper than a subscription with a phone. Want to know more about how Sim Only works exactly? Read what to look for with Sim Only.

Why choose Simyo?

Simyo has been a well-known player in the Netherlands for years. What stands out is the combination of simplicity and reliability.

These are the main reasons:

  • You use KPN's network (strong coverage in the Netherlands)
  • Bundles are adjustable monthly
  • You have a choice of short and longer contracts
  • The provider has scored well in customer satisfaction for years

According to research by the Dutch Consumer Association, Simyo regularly ranks among the best-rated providers in the Netherlands.

The benefits of Simyo Sim Only

Flexibility in your subscription

You can adjust your bundle every month. Suddenly using more data? Then you can easily scale up. Using less? Then you can scale down again.

This flexibility is ideal if your usage varies — for example during holidays or busy work periods.

Insight into your usage

Via the My Simyo app, you can see exactly:

  • How many MBs you have left
  • How many minutes you've used
  • What your costs are

This helps you keep control of your subscription. No surprises at the end of the month.

No unexpected costs

You can buy extra data or minutes if your bundle runs out. This prevents surprises outside your bundle. Simyo also warns you when your bundle is almost empty — handy if you watch a lot of YouTube or Netflix on the go.

Usage in the EU

Within the EU, you use your bundle just like in the Netherlands. This falls under European roaming rules (Roam Like At Home). This makes Simyo also suitable if you regularly travel for work or holidays.

What about Simyo's network?

Simyo uses KPN's network. This network is known for:

  • Good coverage throughout the Netherlands
  • Stable connection
  • Suitable for 4G and 5G

For most users, this means you have coverage almost everywhere — even in rural areas where other networks are sometimes less strong. Want to know more about coverage? Read how Simyo's coverage is.

Contract duration: what suits you?

With Simyo, you have a choice of different options:

  • Monthly cancellable → maximum flexibility
  • 1-year contract → balance between price and freedom
  • 2-year contract → often cheaper per month

Still in doubt? Then a monthly cancellable subscription is a safe choice. You're not tied to anything and can always switch if your usage changes.

Simyo Compleet: extra benefit

Do you have home internet from KPN? Then you can use Simyo Compleet.

This means:

  • Extra data on top of your bundle
  • Possibly extra benefits within your bundle

Handy if you combine multiple services. You not only save on your mobile subscription, but also get more data for the same money.

How does Simyo compare to other providers?

Simyo positions itself as a middle-of-the-road option: not the absolute cheapest, but reliable and flexible. But Simyo has a different advantage: monthly adjustability. With many budget providers, you're stuck with your chosen bundle — not with Simyo. This makes it suitable for those who value flexibility more than the absolute lowest price.

Who is Simyo a good choice for?

Simyo is especially suitable for:

  • People who value flexibility — you can adjust your bundle every month
  • Users who want to adjust their bundle — ideal if your usage varies
  • People who value a stable network — KPN coverage is strong
  • Users who want overview of their costs — the My Simyo app provides clear insight

It's less suitable if you're looking for extreme budget deals or temporary promotional prices. Simyo focuses on consistency and reliability — not on discounts that disappear after a year.

What if you're unsure about customer service?

Customer service is an important point with any provider. Simyo offers various contact options: chat, email and phone. Want to know how other users experience customer service? Read how Simyo's customer service is.

  • Little data (1-5 GB) — suitable for WhatsApp, email, occasional browsing
  • Average (10-20 GB) — suitable for YouTube, Spotify, Google Maps
  • Lots of data (50+ GB or unlimited) — suitable for Netflix, gaming, hotspot

But: the best choice always depends on your usage. How much data do you need? Do you call a lot or very little? And how important is flexibility to you?
