WhatsApp away from Wi Fi? When I am away from WiFi, I do not want to receive nor send messages or media on WhatsApp.  Where on my Moto G can I make this setting?  Thanks !!
There is no standard way, on Whatsapp, to disable send/receive messages. When I want to save my internet, I just go to the phone's configuration and disable all internet conections (leaving just Wifi on, since it is "free") - but it would affect all apps.

The best you could do on Whatsapp is to not download media - go to Configuration -> Storage Data and disable all automatic media download.
