My parents have 3G mobile so I bought jiof M2 wireless router and here is my review:
Internet speed:
The speed of internet is pretty fast even in this router. Thanks to jio for providing this service. The speed is same as the speed comes through the sim in 4G mobiles. So no issues from the speed of the internet.
Connection Reliability:
At some times there will be heavier fluctuations in the signals so that there will be some connection problems. Jio have to take some care to resolve this issue. So there is no guarantee in the connection but when the signal is high you need not to worry about internet speed.
Service and support:
Jio gives one year warranty for this product and can be serviced immediately in case of any problem with the device.
So service and support is good from reliance jio. So I suggest everyone go to jiofi and enjoy internet with fast browsing.
