I cannot video call on messenger using my mobile data on Android

[AC Question]

So my problem is that I cannot make a video chat/call on messenger with somebody when using my mobile data, it doesn't connect. I am using a S7 Edge, latest software, updates, and running as carrier, Vodafone. Any help?

Welcome to Android Central! Which messenger app are you talking about? Facebook messenger, Android Messages, or the stock Messaging app?

I would guess Facebook Messenger, since the other two do not do video calls.

Good point. -- I should've mentioned Hangouts instead of Android Messages. I was also wondering if the OP means making video calls over the carrier's own network, using VoLTE.
