How to make mobile calls via 4G and Wi-Fi
Thanks to the new technologies, you can make calls via 4G and Wi-Fi. Until recently, you could only do this via the 3G or 2G network. What's more, it costs you nothing extra; your usage is simply deducted from your remaining minutes.
Good to know: are you calling abroad via 4G or Wi-Fi? Don't forget to use the country code, also when you are calling to a local number. Do you for instance call from the Netherlands to a Dutch number via 4G? Make sure to type +31 before the number you're calling.

Important!
Your smartphone must have been purchased in Belgium. You can check this in the software information on your phone. Check under ‘Software version service provider’. If you see the code ‘LUX’, your phone is suitable for calling via VoLTE and VoWifi. You will receive an SMS from us as soon as we have activated calling via 4G/Wi-Fi for you.
If you don't see ‘LUX’, then your phone is unsuitable and, unfortunately, calling via 4G/Wi-Fi is not possible with this phone.
Calling via 4G (VoLTE)
After you receive the text, you can start using the VoLTE technology straight away. No further action is required on your part. Now you should see the following symbol on your handset. If you still don't see the symbol, restart your handset.
Calling via Wi-Fi (VoWiFi)
Do you want your handset to be able to switch over to the Wi-Fi network for calls, too? You can easily activate this yourself in the settings on your handset. A few minutes later you will be able to call via Wi-Fi. The following symbol should appear on your mobile phone.
Go to Phone, tap on the three dots in the upper right corner, choose Settings and activate Calling via Wi-Fi.
