Hiiii. guys. I am using Reliance Jio 4G sim for last 5 months. It has very broad network coverage at every places of India and provides very good customer services 24 X 7. It is a best network in India compare to other networks.
It provides unlimited free calling and video calling on any network and also free high speed 4G internet connection. You may watch online videos without any buffering but there is only one issue that sometime call does not connect.
Free services are available at this network till 31th march. After that you may get membership in Jio Premium policy by paying only 99 Rs which will give you daily 1 GB 4G data at a simple recharge of 303 Rs. per month( approx 10 Rs. per day).Overall Reliance Jio has fulfilled all that requirements which a customer needs.
