I buy this phone somedays ago .it is too good . This phone comes with a 4.00-inch touchscreen display with a resolution of 640 pixels by 1136 pixels at a PPI of 326 pixels per inch. TheApple iPhone 5s is powered by 1.3GHz dual-core Apple A7 ( 64-bit ARMv8) processor and it comes with 1GB of RAM. From there, you can turn Airplane Mode, Wi-Fi and Bluetooth on and off. Before, you had to find those switches in the settings. That would have come in handy for my flight to Silicon Valley last week for Apple's event introducing the new phones and software. Likewise, a Do Not Disturb feature is easier to access. It lets you silence incoming calls and messages, though you can make exceptions for certain numbers or for those calling repeatedly, in case there is a true emergency.U can buy this also .thanks
