I am using Airtel 4G Hotspot for my office used and in home. It is very good in connectivity and speed browsing speed.
In my home, it give very good speed and browsing speed is super.
In my office premise, since it connectivity is super and never faced any issue even inside meeting room which is totally locked.
During train journey, in AC coaches, it works very good.
It is handy, good battery backup, small size and comfortable in use. We can carry this in pocket as well.
