In 2024, 92% of the Dutch population aged 12 and older used a smartphone for personal use, according to figures from Statistics Netherlands (CBS). Yet it still happens regularly that you’re just out of range to make a call, whether at home or at work. Fortunately, there’s a solution: calling over Wi-Fi.

But can you actually use this with a 50+ mobiel plan? In this article, we explain how it works, what you can and can’t do, and what alternatives you have if you want to stay reachable.

What is calling over Wi-Fi?

Calling over Wi-Fi means you make your phone calls via a wireless internet connection instead of the mobile network. So you call using your regular cell phone number and use your regular calling plan, but the connection goes through Wi-Fi.

This is especially useful if:

  • you have poor reception indoors

  • you’re in a building with thick walls

  • your mobile network is temporarily weak

Does 50+ mobiel support calling over Wi-Fi?

Currently, 50+ mobiel does not offer native support for calling over Wi-Fi (VoWiFi). This means you cannot enable “Wi-Fi calling” through your settings, as you can with some other providers.

Calling via apps like WhatsApp or Skype

What you can do is call via apps like WhatsApp, Skype, Zoom, or FaceTime. These also use Wi-Fi, but they don’t use calling minutes—only data if you’re not connected to Wi-Fi. You also won’t be calling via your regular cell phone number (except with WhatsApp).

VoLTE and 5G

Since September 2025, VoLTE and 5G have been fully available to all 50+ mobiel customers.

This means you make calls over the 4G network (VoLTE) instead of older networks.

In practice, you’ll notice the following:

  • Faster connection when making calls

  • Better sound quality

  • Ability to continue using the internet while on a call

In addition, 5G provides:

  • A more stable connection

  • Better performance in crowded areas

  • More network capacity

VoLTE improves calling over cellular networks, but does not replace Wi-Fi calling.
If you have no cellular coverage at all, you still won’t be able to make calls using your mobile number.

Which providers offer Wi-Fi calling?

KPN, Vodafone, and Odido

Major providers like KPN, Vodafone, and Odido support Wi-Fi calling by default. You can usually enable the feature in your settings.

Call minutes and restrictions

Note: Calling via Wi-Fi uses your regular call minutes with these providers. So it’s not a “free” alternative, unless you have unlimited calling.

What are the costs of calling via Wi-Fi?

Within the Netherlands

In the Netherlands, making calls over Wi-Fi usually costs the same as a regular mobile call. You use your voice plan, not your data plan.

Abroad

Many providers automatically block Wi-Fi calling outside Europe, or route your calls through the local mobile network. This can result in roaming charges. A smart alternative: use apps like WhatsApp or FaceTime over Wi-Fi.

Is my device compatible with calling over Wi-Fi?

Not every smartphone supports VoWiFi. As a general rule, models from 2018 onward (such as the iPhone 8 or Samsung Galaxy S9) are compatible. With 50+ mobiel, it doesn’t matter yet, but if the feature is rolled out in the future, compatibility will be important.

Conclusion: Can you make calls over WiFi with 50+ mobiel?

Short and honest: no, 50+ mobiel currently does not support WiFi calling with your mobile number. You can use apps like WhatsApp or Skype, but that falls outside your regular calling plan.

Do you want to make native calls over Wi-Fi—meaning using your calling minutes via your 06 number? Then you’re currently better off with providers like KPN, Vodafone, or Odido. If you’d rather stick with 50+ mobiel, you’ll have to wait and see if they add the feature in the future.
