On further analysis i have found the MTU value is 1514 on UDP. I have a doubt that the same value send in wifi network but call working, the same length not working in 3G network.
How it is possible? if the packet length crossed 1500 MTU it will get problem in wifi also. But we having the problem in 3g network.
Please help me in advance, i'm stuck up with this problem for more than month.
