I am using this sim since it’s launch.jio sim gave us free internet for a span of 6months which made us addict of using internet.After I thought it would increase rate of internet, but it is giving 1Gb per day for 3months and for a cheap and worthfull price.It is having good connectivity.It is giving us high speed internet for low price beating all other mobile operators in india and became king of telecom companies.it is also giving chance to do unlimited calls.So jio sim is the best sim in present market of india
