I bought this dongle & returned it back in less then 3 months. I had bought it for Rs.799.
I started using it by installing its drivers. I used it was for few hours & then connection was getting reset every few 10-15 mins gap.
I saw that dongle was getting very hot too. It claims for 3.1mbps speed but it was no where near it.
My speed test result score was 890kbps. Way below par compared to even tata photon plus.
Their post paid data plans are attractive but the dongle is so pathetic to use that its not recommended.
They need to improve the quality of hardware to fully utilize their data plans.
