The imo app is the greatest app to contact the people, really I enjoied it. While I was in video chatting, it is also useful to call my contactes. The imo messenger very super to me. Its also providing messages to contact my friends. There is no need to recharge my mobile sim to talk with my friends. Because it providing the voice call, the speed process of this app is very excellent. Really I use my imo messanger to contanct my friends in daily.
