I use jio phone many times. It is actually a good phone in this price which is fifteen hundred. But one thing is not good in this phone which is its KIOS operating system. The phone supports only jio sim card. Which is not good. But the recharge of one month is 49 rupees. The customer services of reliance jio phone is very good. They solve my problem as soon as possible. The phone hangs up and some times it does not work properly. The charges and billing of Reliance jio phone is good. They give me a bill of phone.
