Now the days every one know jio(reliance telecom product)
I personally use jiofi and its really feel good to using its internet facility
Now its free so speed will affected and in-spite of that speed is about 10 MBPS of its isp connection
u can connect lot of devices its about 31 but battery of jiofi is very fast draining
connection reliability and service support both are good as per my personal experience
the network( signal strength) is quite low as compared to other mobile operator
service support is available 24*7
Thanks
