Reliance jio I got the sim card in gery early days of announcement on my samsung galaxy on5 mobile.
At that time internet speed was fabulous and I was getting an average 8-9 mbps. I was quite satisfied. But after they announced jio 4G sim for all LTE supported mobiles. And it is getting worse then after.
May be they are not able to control the traffic or too many users.
Now my internet speed is around 1 mbps which is like 2G.
It was time when I click a video on youtube and it was running on 720p smoothly??. And its a time now where I have to run a video on 144p to get buffering free video.
Jio gives speed in play store and youtube but when it comes to download something from browsers speed is not like 4G.
If I talk about calling experience its completely bad not happy. Everytime I try to call someone they keep running the audio is root ki sabhi line vyast he. Even after trying for 20 times I am not able to call successfully. At last I need to switch the other sim and call.
They have to do something with their setup and improve in every department.
Just giving everything free is not enough you have to give better user experience.
