I am using jio wifi device from last 3 months and I experienced that it is not that good as they show in their advertisements .
Big issue is network .no proper range is there and because of network issue you wont be able to use that wifi device as it only works where there is network for reliance jio .when I started for the first time it was quite good but later after 1 week I was upset with jio service and was not satisfied .finally I stopped using it .
