Myself Ramanand and going to review on Airtel mywifi which i using since last 2 years. I bought it from flipkart. Firstly i want to describe its built quality, its built quality is good, it comes with micro usb charging port, one power button, one wps button, reset button and comes with high capacity battery of 2300mAh. Its size is small and can easily adjust in you pocket. It supports high speed 4G LTE network. I am using it in office use and battery backup is approx upto 8hrs. After that it still lasting for 1more hours before getting totally drained out.
Speed is quite good. I did a speed test with my airtel prepaid sim by comapring with my Mobile and i find that this device almost getting 50% more speed then my mobile. But yes, speed also depends on the place you are in. Range is good, bot soo good or so bad. The ony issue which i faced is, sometimes after switching it on the network signal in the device shows in red color and as a result you won’t be able to access internet, Overall this device is good
