My Verdict - I have been using the device for a while and I'm quite happy with its performance. I used to activate internet packs on two of my cellphones but after purchasing this device I connect both my cellphones to it directly. I power up this data card via an adapter (as shown in the picture above) or through one of the USB ports available on my PC. When I use it through the USB ports on the computer, it allows me to access its internet connection simultaneously on computer as well as on my smartphones. You can also go for Huawei E8231 which has similar specifications but different download/upload speeds.

Nice information indeed. Instead of getting tied up to a particular operator, you can use any SIM card of your choice and you are free to change it as many times as you would please. Great app in addition to a great USB data card.

Please can somebody tell me why can't I access internet after successfully installation of device even with 3G network? It shows limited on my connection.

Swati, is that issue resolved for you? Even I am facing it for a while and not able to figure out the exact cause and solution for it either on Win8.1/8.0.
