I purchased this because I don’t have a 4g smartphone afer using of long time I am disappointed with this product .i have quite a lot low speed than 3g with this one but I purchase jio 399 plan which gives 1.5gb data/day and unlimited calls bu. I don’t use the single gb even I went jio service center but they says that they don’t fix the error.my all money and my hope went from jio now I use a Vodafone network which is more good than jio.i back my hopes and I feel so good after all of things happened by jio I lost my all money so all of the reader please don’t purchase this one go with another one.
