Many peoples of India are poor so they unable to use smart phone service but due to arrival of jio phone it diminished the poorness thought among the people, also in many institution like coaching or schooling the students are not allowed to use smart phone so they choosen jio phone service to meet their needs; it contains many apps like my jio to know data status, gallery for photos, YouTube for music video movie, Facebook for connecting with friends and family, and many other apps also there so useful phone for indians thanks.
