I got a Jio sim card nearly 27 days earlier and till now the experience to use it is ok ok. As when I initially started using Reliance Jio sim card the first problem I faced was that the registration process but when I got it I used it and the download speed was around one to six mbps. then slowly day by day I faced some issues for speed. Currently I get a speed of point two(0.2) mbps to Two mbps. the major limation of Jio is that if we want any help from customer care then it is not worth of spending thirty minutes for just getting the call connected as the customer care executive rarely help us due to lack in technology. The myjio app also is not so good as we could not track our data usage. There is also limited 4G data provided after 4GB data the speed decreases to two to 30 kbps(Download speed). There is even problem in connecting call.
