From the starting of jio service I am using the Jio sim and mobile internet. I think the introduction of Jio mobile service changes the face of Indian mobile and Internet service. At first the internet speed was slow, but it become faster. In rural areas I got a speed of near 9mbps speed. With my experience I say that Jio is the largest and high speed mobile and internet provider in India. Because of the entry of jio into mobile and internet service, other mobile and internet service providers forced to reduce their charges.
