I have been using reliance Jio from the begging.jio has attract most of the customers due to fast networking and it’s free services.but unfortunately in many places the coverage of Jio network is very poor compare to other.althoug it is the fastest network then any other networks in India bt many people didn’t get the advantage of this fast networking due to lack of network coverage.but then too Jio network is good and is loved by most of the people across India.and many has switched from other sims to Jio due to its advantages
