Agree on other parts except for call quality. On 2G /3G even on say weak signals (2 or 3 bars of signal) you get good call quality. On JIO even in 4G coverage I have issues with call quality. The person on other end says I sound like an old radio station. That needs to change. The only problem for me today with JIO is I cannot use it as my primary calling no. Network is available almost everywhere and data services is also good(most of the times) At times the data is connected but one cannot stream even a normal youtube video or FB page. This is not acceptable is I want to use it as my primary no.
IMHO the plans are nothing much to go gaga about. Its the same as on other international all LTE networks. Only costing low than that.
And AGAIN 28 days?????
