WhatsApp or Viber

My relatives are far away from me and we communicate a lot online. Of course we often send videos to each other and apps often don't work. What would you choose for your phone?

I personally would prefer, if I were you, to not just communicate via video. But just communicate via video chat, at least because it's more convenient than sending a video. And about apps, to be honest, I don't know.

What video chat are you talking about? I read recently that there is an extended gb whatsapp app that allows you to send large videos and also use features that are not available in normal messengers. I've read very good reviews about this app and the good thing is that it's totally free to download
