Cheapest Sim Only contract: how to find the best deal

Although a lot of people use Sim Only contracts, 49% of consumers (ACM) believe they could save money on their mobile contract by switching to a different provider, for example. But which provider? Providers use different promotions, temporary discounts, and fine print that make it difficult to get an overview. In this article, you will learn step by step how to find the cheapest Sim Only contract that suits your usage, wishes, and budget.

What do we mean by “cheapest Sim Only”?

Price vs. value: bundle, network, and service

The cheapest Sim Only is not always the one with the lowest monthly fee. What you get for that price is just as important. Therefore, pay attention to:

 

  • How large your data bundle is.

  • How many calling minutes or text messages are included.

  • Which network you use (KPN, Vodafone, or Odido).

 

A contract for €4 per month seems affordable, but if you regularly exceed your bundle, it can actually end up being more expensive.

Budget bundles vs. unlimited: when to choose which?

Do you mainly use your cell phone for WhatsApp and some surfing? Then a small bundle (2-5 GB) is often sufficient.

 

Are you someone who streams a lot, makes video calls, or works on the go? Then an unlimited internet contract is often more affordable.

How to compare prices smartly

Temporary promotions and discounts (duration & conditions)

Many providers attract customers with low rates, but these often only apply for a few months. So always check how long the discount lasts and what you will pay afterwards. 

Contract duration: monthly cancellable vs. 1-2 years

A one-year contract is usually cheaper, but monthly cancellable contracts offer more flexibility. This is useful if you are not sure how much data you need. 

Additional costs: connection fees, administration, EU roaming

Be aware of any one-time connection fees (often €15-€20) and check whether EU roaming is included. This will help you avoid unexpected costs when abroad.

Fair Use Policy and conditions for unlimited internet

“Unlimited” is not always truly unlimited. Most providers have a Fair Use Policy. For example, your speed may be reduced in case of extreme use. It also sometimes happens that your internet speed with an unlimited contract is lower than with a limited contract. So always read the terms and conditions carefully before choosing a bundle.

Network and quality

Networks in the Netherlands: KPN, Vodafone, and Odido

The Netherlands has three main networks: KPN, Vodafone, and Odido. All three offer nationwide 4G and 5G, but performance may vary by region. KPN often scores best outside the city, while Vodafone and Odido are stronger in urban areas.

Coverage differences per region and actual speeds

Use an online coverage map or test your speed with a Speedtest to check the coverage in your region. Only then will you know exactly which network can achieve the highest internet speed in your region.

  1. 50+ mobiel - Average €5,63 per month (internet speed 200 Mbit/s)
    With 50+ mobiel, you receive a 50% discount for the first year and pay €3.75 for 10,000 MB. Unlimited calls and texts are included for free. After the first year, you pay €7.50 per month, which works out to an average price of €5.63 per month.

     

  2. Youfone - Average €6,38 per month (internet speed 200 Mbit/s)
    With Youfone, you receive a 50% discount for the first year and pay €3.75 for 10,000 MB.

  3. Simpel - Average €7,75 per month (internet speed 150 Mbit/s)
    At Simpel, each bundle costs €5 for the first year. In the second year, you pay €7.50 per month for 10,000 MB.

Key differences between providers

All three providers offer similar bundles, but the quality of the internet and service can vary. Therefore, don't base your choice solely on price, but also on what is important to you. Is customer service very important to you? Then choose 50+ mobiel. Would you rather have the option to add faster internet to your bundle? Then Youfone is a better fit for you.

How to choose the cheapest contract

You now have a general idea of what to look for to find the cheapest contract. But how do you get started? We have drawn up a step-by-step plan for this.

Step 1: Determine your data and calling profile

Check your phone settings or contact your current provider to find out how much data you use each month. This will give you a clear idea of how much you need and make it easier to compare bundles of the same size in terms of price and features. The average Dutch person uses between 6 and 10 GB per month.

Step 2: Check your coverage

Use an online coverage map to see which network scores best in your region. When comparing bundles, you can filter by this network to make a preselection.

Step 3: Filter similar bundles by price

Now that you know how much data you need and which network suits you best, you can filter by price. Use our comparison tool to set all filters and sort by price, data volume, network, and contract duration. 

Step 4: Determine your preferences

Now that you have a good selection of bundles, it's time to make your choice, but how do you do this? There are so many bundles, all with their own advantages and disadvantages. To make the choice as easy as possible for yourself, it is wise to determine what is important to you. Do you find good customer service important, or do you prefer high internet speed? List your preferences and see which bundle from the selection matches them best. 

Common mistakes (and how to avoid them)

Choosing a bundle that is too small and incurring out-of-bundle charges

A bundle that is too small can lead to high out-of-bundle charges. It is better to choose a buffer for certainty.

Forgetting the discount period (price increase after promotion)

Make a note of the end date of your discount and compare again as soon as the price increases. That way, you'll always get the best deal.

Not checking roaming and 5G conditions

Not every provider offers the same conditions outside the EU. Check this before you travel. 

Conclusion: the smartest choice for the cheapest Sim Only contract

An affordable Sim Only contract is not just about the lowest price, but about the right balance between data, network, and service. Therefore, choose the bundle that suits your usage and look beyond just the price tag. It's the extras, such as a stable network, reliable customer service, and fast internet, that make your contract truly affordable.
