   Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Press and hold the Side button until the Apple logo appears on the display.

   Reset Network Settings

   Navigate to Settings > General > Transfer or Reset iPhone > Reset. Select Reset Network Settings and confirm. This clears all saved Wi-Fi passwords, Bluetooth connections, and VPN configurations.

   Note: Back up your device before performing a network reset, as this reverts all connectivity profiles to factory defaults.
