I would say jio is not the best.
The company has launched the product bagged with offers and free services and what happened is now other sevice providers are now in competition with jio and offers a good scheme than jio now. Jio is increasing the data packs rates every time and thats what public don’t like . Everyone has availed this service for the reason of least cost but now most of us will think a while before chosing jio and any other service provider as jio is not providing that much fast services as used to do earlier.
