Ways to make calls through Wi-Fi calling only on a Samsung device?

[AaronYo]

Ltl ftp. And I'm on mobile so forgive me for having **bleep**ty formatting.

So I'm traveling abroad, and was wondering how the roaming charges are gonna apply when my call is initiated through Wi-Fi. I found [this](https://www.fido.ca/consumer/content/wifi-calling) where they state that if the call/text is initiated through Wi-Fi calling towards a Canadian number, no roaming charges will apply. That's pretty neat.

But what should I do to make my phone "WiFi calling only"? I can only set my preferred method of calling, but can't disable calls through mobile networks.

Thanks for all the help:)

Hi @AaronYo,

You can put your phone on Airplane mode then enable WiFi this way nothing comes in/out the mobile network.
