I don’t know why but from yesterday I am not able to do any video calling from my 3g mobile phone. Every time I am trying for a video calling an error message just pop up unable to call. But for ordinary calling it is working just fine. I had also reset my 3g mobile phone but still problem is same. I have also contacted with the customer care but they are telling that it is not a server problem. So I want to ask from you guys, what I need to do?
