Reliance made simple phone with 4g services and this phone is for those did not use smartphones and want to upgrade basic phone to some net uses.
Network of the jio phone is very good but this phone is not for good internet services. My mother is using this phone and she is using only for calls.
Coustmer services of this phone is not so good it hangs alot. It has 4g services but you can not use this phone for heavy uses and always freezes in time battery life the phone is approx 2-3 days.
