The Reliance jio network is the best 4G network in India. Starting jio 3 monthes free data sms and free hd voice calling but April 2017 is new and chip plans available and jio prime membership is Rs.99 plus recharge. Jio dhan dhana dhan 3 monthes plans.
Rs.309 1GB high speed data + free 100 sms & unlimited hd voice calling free
Rs.509 2GB high speed data + sms & unlimited hd voice calling free. He is two plans available jio prime members only. So friends jio is fast and low price plans but network is very fast after your data is finish so unlimited data on 128 kbps.
My suggestion is jio 4G is No.1 VoLTE network in India.
