Reliance jio is a fast growing company in India which provide 1 gb/day very good speed data. Jio network is good. Reliance started offering this device in September 2016 which allows you access Reliance Jio 4G cluster of services(Voice calls, Video calling, Text messaging, Multimedia messaging, TV, Entertainment). Most importantly, all these services are COMPLETELY FREE, and UNLIMITED Usage is allowed March 31, 2017. I got a speed of approx 18mbps while downloading Youtube videos. Nominally, I’d say I get a speed around 600-900 kbps, which is more than decent considering the Indian conditions and how Telecos are ripping the consumers in the name of 3G/4G and other nonsense. Considering that customers are putting up with 2G speeds while paying for 3G, this is indeed very satisfactory.
