Dear friends I an going to share my thoughts about zen ultrafone 501.Sound reception: zen ultrafone have no much demand in india. Its sound reception quality is not very good because all buyers want according to their fullfillment of desire ans this have not all those.User friendly: zen mobiles are no more freimdly for users because of low features and benefits.Style and design: its style and design are not according to modern way and also not very good.Other features: it has no nore features like 4g or maximum RAM. And ROM.Value for money: it is very cheap because it is simple not technical phone and android phone.
