Reliance jio 4g is the greatest network. I used jio 4g when I work in reliance 4g project in pan india. I used it in samsumg galaxy 4g mini. When we checked internet speed of any network we allows get avg up to 60mb/s, this is the download speed and upload speed is allows 30mb/s. When we get downoad speed less than 40mb/s, then we manually increase the speed and when we get upload speed less than 20mb/s, then we manually increase it.
You can do voice call, hd video call, online movie, music and all others service.
Most important point- jio 4g plan is very lowest cost compare to all others.
Thanks for read it
