Reliance Gio is most cleap operator at this time and not only this it has offer good service also
I have take prime membership of this and done 303 rs recharge over it
Mainly I used it for data and it offers 1gb per day 4g data that is enough for normal used
Reliance gio has provide coverage to most of the places even in villages
About calling it connects calls very fast and as we all know data calling and sms all facilities all are cover under one recharge
I recommend this operator to all
