Reliance Jiofi is the amazing and awesome device launch by Reliance Telecommunications Limited. This can be considered as the best dongle in India till date. It also looks attractive and it has proper signal catching property and it has proper signals all the time. It has two buttons , one of on/off and another of WPS, which helps in connecting to new devices.
With the Jiofi, there also comes a Charger that can be used to charge Jiofi the same charger could also be used with Android devices and some other devices to charge them.
Inside it, there is a slot of Data Sim and memory card.
We could insert JIO sim in the sim slot only nano sim could be fitted.
The speed of Jiofi is good and it could even reach to 5 to 7 mbps.
I could recommend jiofi as the best device for data connection.
