Ok i can do video call with my mate - he is on PlayBook calling me. No problem. But my other mate is in Switzerland now, and we can chat on BBM but there are NO video icon in the corner. He is on WIFI and i am on WIFI. I have Vodafone SIM card and he has a Russian megafon SIM. I have my old BlackBerry service on through Vodafone, he doesn't have bis at all. What is the problem? Anyone know?
