Reliance Jio is the one of the best popular 4G mobile operator in India. Jio have some difference from other network, only Jio is providing VoLTE ( Voise over LTE ) that means the we can make or receive calls with using 4G data conectivity and The Reliance Jio have 2x speed than other network.
The call quality is not well, it need some impruvments.
Overall experience Reliance Jio is decent network thats available in India
