I am using Reliance Jio from last two months. When I purchase it with Lyf Mobile then its net speed like a plane. I enjoyed it one month. Then slowly slowly its network going to down and now my phone doesn’t download any movie or file. And my facebook app is taking so much for load. But I like it because its free for everything. Calling is also free but mostly calls not conected. For call try again and again and again then your call conect. I purchased this sim with lyf mobile in 7500rs. This also not good.
