WhatsApp has been attempting to roll out its calling feature over the course of a month now, and today, it kept its window open for users to get in on the action before WhatsApp closed down the invite system yet again. This time, though, if you got the call interface activated it appears that it will stay that way for you permanently and you are still able to make calls, but you won’t be able to invite anyone from it now that the window is closed.
Details of how the invite system works have been pretty well worked out so far without much assistance from WhatsApp. If you’re a WhatsApp user and you’re looking forward to being prepared the next time one of these windows opens, you can check the criteria after the break.
So, of course, you need the latest version of WhatsApp (2.11.531), which you can grab from the APK link I’ll include at the bottom of this article.
The next part is tricky depending on how many people you use WhatsApp with. You’ll need to get a WhatsApp phone call from someone in order to activate your interface for calling. Once you’ve gotten that call, you’ll notice that WhatsApp will now have three tabs at the top (not unlike Google Hangouts if you have Hangouts Dialer installed). You then will have the ability to “invite” someone to WhatsApp calling by placing a phone call to them.
No official word yet on when WhatsApp will be opening up the next invite window. Perhaps they’ll ditch it and just release the feature globally next - who knows?
