Hello friends. I am using reliance jio sim for the past 1 year. I rarely faced issue while calling. Suddenly the call is end while speaking. If I want to speak with the particular person I wanted to call them 5 to 6 times. While speaking it gets ended. After that internet connectivity. The network speed is very very slow while compare to other sim. Data rates are too high when compares to other network. Even the data plans are also high. Signal strenght is very very poor.
