WhatsApp is a great way to communicate but it all comes down to when u start voice or video calls and your on WiFi but when your off WiFi and using your data it's perfectly fine. But when you use WiFi it always crashes and WhatsApp is down for no less than 2 hours. It's a joke!!! It's not just my WiFi or my phone either. I have tried multiple phones and WiFi and it still dose the same thing. I would not recommend this as most people like to call instead of text each other.
