I have been JIO sim for more than two months.
Their claim that Jio is the cheapest and fastest network is not correct. Even now voice call to many numbers does not work. What is the use of having a phone which can not be used?
It works at some places and some times. Speed when it works is about 2G speed at many places. Over the period of two months, it has deteriorated. After the free period, I am going to discontinue their service.
