D z Rohingya

Today as usual I try to text my friend and it doesn’t work so I get here to text me START and it works but then the next day she texts me first then I try to respond and I can’t send and I also can’t receive messages either and sometimes I see the text notifications but I can’t see it when I open the app, I’ve had this app for while and none of the things that I try work. I CANT TEXT ANYBODY AT ALL!
