Apple phones don't turn on Bluetooth. Why can Apple Watch receive messages?

Under the same WiFi, the watch can receive information even if Bluetooth is turned off.

There are two ways to directly unpair the iPhone on Apple Watch:

Method 1: Cancel the setting of Apple Watch.

1, activate the screen, and tap the digital crown to enter the App icon matrix.

2. Click the settings icon and enter Settings > General > Restore.

3. Select Clear All Contents and Settings, and then select Continue when prompted.

4. After erasing all contents and settings, Apple Watch will restart into the language selection interface and start pairing again.

Method 2: Cancel by using the forced touch menu.

1. Activate the screen, press and hold the side button (power button) for 2 seconds, and the sliding shutdown interface will appear.

2. Press the screen hard to activate the forced touch menu, and then all contents and settings will be cleared.

3. When prompted, click the green check mark to erase all contents and settings, and the watch will be restarted, and then the same as above.
