Recently Reliance Jio Launches their 4G services to the all Customers who have 4G Supported Phones and they gives world best plans for their customers that is Free 4G Internet, calling and sms services for 90 days free.
I used Jio sim since August and they Will extend their free services 31 Dec 2016 that mean I get 5 month free service and I am very satisfied about their 4G LTE internet Speed and the HD voice Calling no any issue with Jio except the Calling from Jio to Other Networks.
They give a wide range of the 4G LTE networks and HD voice calling But the other network provider create issue for the jio they dont give them Interconnect port for doing call to the other networks that why the Jio drops over 100 Million call in a single day.
Jios 4G internet speed is the very fast as compare to the other networks jio give upto 65 Mbps downloading and approximate 35 Mbps uploading speed in my location.
yes they cap on the internet usage but the 4 gb is sufficient for the day.
Best part of the jio is they give the free voice calling for life time and 1 GB 4G internet only Rs. 50 which is the crazy deal for the indian subscribers.
