Does Truemove block messenger calls?

[FarangFB]

Every time I call or receive a call  (voice or video) on facebook messenger, I keep hearing that beep and it never connects. This only happens when I'm using my Truemove 4G connection and only happens when using Facebook  messenger - if I use Line messenger it works perfectly. For other applications such as youtube everything works very well too.

 

My wife also has a Truemove simcard and has the same issue. It's not our phones because if we connect to a wifi we can make those calls without issues.

 

I'm strongly suspecting that Truemove deliberately blocked FB Messenger calls to save bandwidth or something. Could that really happen?

I got this popup today while using FB Messenger. So it seems it's actually blocked. Oddly, Line messenger calls still work normally.

Did you ever find a way around this? And does this happen on AIS internet as well?

so 'technically' if you changed your phones settings back to downgrade to 3G; what can True then justify in continuing to block you?  ????
