Yesterday, when my balance was nearly Rs. 0.56. Then I tried to connect with pd proxy and it got connected with the udp port- Hidden Content: **Hidden Content: Only Proactive member can see this** and I used almost 500mb of data. After some time I called someone and by balance became 0.00 and then I tried to connect using pd proxy it didn't connected at all. I think this udp trick is working only when our balance is between 0.50 and 1.00. Reply whether its working or not then I will improve this thread and post it with full details. This was tried by me in Aircel Delhi sim.
