Amazing.
When reliance start 4g offer I get sim card from digital express mini in hyderabad.
When I came to ahmedabad by train during journey I got upto 25mbps speed when I download in ucbrowser. And average speed is also 2-5 mbps. At some place jio network very poor, but overall it is good.
Reliance jio is must try and it is very huge start up by reliance for start 4g service in india without any cost for all 4g device which is amazing.
Jio call and sms throught which is not so good because it is sometime not work on some mobile number.
