Wind 7s of lyf is a very good cell phone. as I m using it from last 2 months, so I can say that it is very simple to use it. and all my work for which I purchase this mobile is fulfilled. it is a 4g supportable mobile with free jio sim. and the mobile is working great so what else a consumer need at this price. for me its a full paisa vasul mobile. sound quality is good, look is also good, battery consumption is low that means great durability. one should go for it, its a great phone.
