Perform a Forced Restart on the iPhone.


Force restart iPhoneApple SupportOfficial Apple Support › guide › iphone › ios


If no help, tap Settings > Wi-Fi. Is the setting to Turn On Wi-Fi "grayed out"?


Then, tap Settings > Bluetooth. Is the setting to Turn On Bluetooth "grayed out"?


If both settings are "grayed out", the chip that controls both Wi-Fi and Bluetooth has failed and the iPhone will require service at the Apple Store / Genius Bar or an Authorized Apple Service Provider (AASP).


You can find a list of authorized service shops in your area by tapping on the link just below:
