When I get free Jio 4G sim with my LYF Wind 6 smartphone, I was so exited about it. They gave me 3 months of free data, massages and calls. It give me good internet speed in starting days. But after 1 month it gives me only 100 - 200 kbps speed. It run internet with speed in morning time only after morning speed slow down for whole day and night. The voice calling and video calling through this sim card is also a big problem . When I call someone everytime it shows line is busy . There is the same problem in video call also everytime it convert video call into voice call. So, my experience with this sim is really bad. I am going to replace my Jio sim by my old sim card. So, don’t be fool by fake Jio ads . Choose your network wisely.
