Choosing a Sim Only plan seems simple, but in practice it comes down to one question: how much data do you actually need? And how much do you call?

The right bundle depends entirely on how you use your phone. Some people need only a small data bundle, while others stream daily, navigate, or call frequently. Choose too little and you'll run out. Choose too much and you'll pay unnecessarily.

In this article, we'll help you determine which Simyo plan and Sim Only bundle best match your usage.

How do Simyo bundles work?

With Simyo, you build your own bundle based on two components:

  • Data (MBs or GBs)
  • Call minutes (or unlimited calling)

You can adjust these bundles monthly, both up and down. This means you're not locked into a choice if your usage changes.

This makes Simyo especially suitable for people who value flexibility.

What types of Simyo bundles are there?

Simyo offers different types of bundles, depending on your usage. Below you'll find the main categories.

Small bundles (light users)

Do you mainly use wifi and little mobile internet? Then a small bundle is often sufficient.

Suitable for:

  • WhatsApp and email
  • Occasional browsing
  • Light calling

Medium bundles (average usage)

Do you use the internet daily, but not excessively? Then you're usually fine with an average data bundle.

Suitable for:

  • Social media (Instagram, TikTok)
  • Navigation (Google Maps)
  • Occasional video watching

Large bundles (heavy users)

Do you use a lot of data, for example for streaming or hotspot usage? Then you need a larger bundle.

Suitable for:

  • YouTube and Netflix on the go
  • Video calling (Zoom, Teams)
  • Working via your hotspot

Unlimited calling bundles

Do you call a lot? Then you can choose unlimited calling.

This is useful if you:

  • Have frequent contact with family or clients
  • Don't want to worry about your call bundle
  • Use your phone a lot for business

How do you choose the right Simyo bundle?

Choosing the right bundle starts with your own usage. Ask yourself these questions:

  • How much data do I use per month?
  • Am I often on wifi or not?
  • Do I call a lot or very little?
  • Do I want flexibility or the lowest price?

Not sure? Then it's better to start a bit lower and increase your bundle later. With Simyo, you can do that every month.

Adjusting your Simyo bundle: how flexible is it?

A major advantage of Simyo is that you can easily adjust your bundle.

This means:

  • Need more data → increase immediately
  • Less usage → lower your bundle
  • No long-term commitment needed

This flexibility ensures you never structurally pay too much. You adjust your plan based on your current situation.

Bundles and network: what does that mean for you?

Simyo uses the KPN network. This means your bundle isn't just about the amount of data, but also about quality:

  • Stable connection
  • Good coverage
  • Suitable for 4G and 5G

Especially with larger bundles, this is important because you're using the network more intensively. Curious how the network performs in practice? Read more about Simyo's coverage.
