I have been using Jiofi and Jio connection since the time they launched and bought the device for 999/-rs during the offer period.
Without going into technical details, I would like to share my experience.
Things I liked:
Cheap plans of under 500rs for a month.
Fast network connection and speed that doesn’t break.
Easily chargeable with any usb charger.
Vast area coverage.
Ease of operating with 1 button, hence no confusion.
Things I didn’t like:
Gets heated while charging, even the charger heats up.
Even after securing with a password, someone under a distance of 15-20metres can easily access internet using our wi-fi connection for free. This way it is not secure and also does cost us more than what we use.
