How do I turn my phone off I hold the button down on the right and nothing happens please can you help me also my location is wrong
You can turn your iPhone off by either holding down the volume up button and side button at the same time until you see the power off screen, or you can quickly press the volume up button; then press the volume down button and then hold down the side button.
As for your location situation, you can change your iPhone's region by going into Settings > General > Language & Region > Region.
