I have been using iphone 5s from last 2.5 years and im happy to say that this mobile doesnt got any problem from the day im using it . this is a full of worth product of apple . I live in india and here apple phones are considered as a status symbol of a person . with one of the best features this device have taken the major share in market after 1 year of its launch, even its battery backup is good and sound quality is also best . the price of this phone is best with its features . as the other iphones are expensive . this comes with a lower price which a consumer can easily afford .
