My iPhone doesn’t updated

See this for help:--> Get help with over-the-air iOS updates – Apple Support

If the issue still persists, try to update your device using iTunes on a computer. If you don't have a computer, borrow one from your friends, or ask for help at an Apple Store or AASP.--> Apple – Location Selector
