I don’t know the exact reason behind this but from last one week my at&t mobile internet is working too slow. In general the downloading speed of my mobile internet is about 2 to 3 mbps but right now I am getting it in KB. While the time of internet surfing also it is to slow. I had already done complaint against this to at&t customer care but they are telling that this problem is not from their side. SO I want to ask from you people, what might be the problem?
