If my bf's viber shows he's online and then in the middle of the night it changes to Offlineoffline, what does this mean? Does it mean that when he's at home and within reach of the internet it shows him to be online if his Viber app is active? And does it mean that he has gone out of range of the internet if his viberViber states he's Offlineoffline? (He has a Samsung Galaxy Fame.)
