Believe me guys this is truly unlimited unlike other service provider and I am getting speed of 500 Kbps to 750 Kbps most of the time. Sometimes 1 to 1.2 Mbps if the device is placed towards the direction of the tower. I attached picture of speed test in this review and you can see the speed.
I am using this with tp link wifi router(Model number: TL- MR3020) so I can connect to many other device.
Getting a device is somewhat difficult because many don’t have enough knowledge about this device, set up is easy and the cost of the device is 1250 rs. I strongly recommend you to have a demo before buying the device as it is available in the bsnl office.
