I and my brother both have reliance jio sim which we use through LYF Mobile. In advertisement they were saying free calls, free internet and free many many things. Yeah they are giving free internet but not free calls or even sms’s. There internet speed or 4G speed is near around 22 Mbps in night and nearly 100 kbps in day. You have to fill the balance if you have to call and moreover many a times lines are busy most of the time. I would say if you want to use internet free of cost and are getting free LYF mobile or so, then go for jio otherwise broadband is best. And moreover other networks 4G speed is far better than jio
