I have been using reliance jio sim from more than 1 year and its has been a great deal of money with this network as the services like incoming call , outgoing calls , sms , roaming , internet speed one year free subscription to jio for which we dont have to pay is great.i have been to more than 4_ 5 states in india example Himachal Pradesh, punjab, haryana, maharashtra, delhi , tricity .
The services are great and its hasn't been a problem for me
