How many of us are facing this problem. After doing two week extensive research, i figured out that this is ISP (reliance) created issue. Look to me that while rolling out their TRULLY UNLIMITED 3G pack, they have put this cap limit on their server due to security reasons. I checked it on following APN in DELHI circle *rcomnet *smartnet *rcomwap *smartwap facing this issue on mobile as well as Data-card (Huawei unlocked) Please comment below if you are also facing this and which circle your SIM belongs. If anyone have find out any solution, then please mentioned it too. PM me and I will add it over here for everyone's benefit.
