Hi, i am using the Yoosee app, with the Kerui Corina 720P camera. When i connect the Kerui Corina 720P camera with a PIR motion sensor i can not receive alarm messages outside of my wifi network. I can not bind my mobile phone. the message is: Current country or region doesn't support binding phone numbers. I had it up and running for one day, the yoosee app pushed me a alarm message, but now at the second day the yoosee app does not alarm me in 4G network outside my Wifi network. Please help me to bind my mobile phone in the "security alarm settings".
