To connect the iPhone X to a wireless network and turn wireless on automatically, first open the phone's Settings menu and then select the Wi-Fi option.
In Wi-Fi Options, turn on the Wi-Fi switch to enable wireless functionality.
Then select the wireless network you want to connect to from the list and enter the password (if required).
Once the connection is successful, the iPhone X will automatically remember the network and connect automatically the next time.
If you want to turn on the wireless function automatically, you can select the \"Wireless LAN\" item in the Settings menu and turn on the \"Auto Connection\" option. This will allow the iPhone X to automatically connect to previously connected networks within range.
