My QX1050 correctly recognizes my carrier as Dodo and allows me to connect to the internet via mobile network or by wifi, but I can't make or receive calls even though it shows there is a strong mobile network connection. when someone calls me it says unavailable. when i try to make calls the screen shows that its calling, but there is no sound at all, no ring tone and eventually i get the notification mobile network not available. has anybody else had this issue? I'm having trouble coming up with search terms because its such a general sounding issue.
