I am very satisfied, because it is currently working with JIO and I am getting speeds of upto 3-5mbps( according to my area this speed is probably the most I can get) .It also has 1 year warranty and there are service centres in India too( But not many centres in India) .
I’ve also put a micro sd card of 8Gb and it is reading it. I have no complaints about this product in accordance with its software. However connecting sometimes disconnects and it reconnects automatically, the design of the data card is not to my liking and the white design of the data card gets a little dirty too. Except these cons the data card is very excellent!
