Hi friends.i am using jio for last 3 months.it is the best mobile operator in India.before jio I used airtel it is also one ofe the best operator compared with jio airtel is poor in signal quality.jio is offering high speed internet service(4g).as all u know that jio is providing free internet for last 3 months and recently it extends its date to march 27 I felt very happy.coming to signal quality jio supports LTE, and VOLTE which is 4g, in 4g the voice calls are very quality I never experienced such a quality voice.And coming to internet it gives 4g speed.at my home 20mbs speed is coming very fast.but jio put a limit for the user it is of 4gb per day.but in happy new year offer it is reduced to 1gb.but only drawback of it is call drops.as other operators are opposing jio they are not allowing jio calls to there networks it is one of the problem with jio.And due to increase in jio customers the internet speed also decreased in some areas.
