If you are having trouble pairing your Apple Watch to your iPhone, there are several different solutions to try. The first solution involves restarting your iPhone and resetting Bluetooth and network settings. This method works for some models of Apple Watch, but it will not work for others. To resolve the problem, try these other solutions:
Restarting your iPhone
If your Apple Watch won't pair with your iPhone, try restarting your iPhone. This will re-establish all network settings on the iPhone. Restarting your iPhone after Apple Watch pairing can also fix Bluetooth connectivity issues. To perform this task, hold the side button on your iPhone until you see the "slide to power off" toggle. Next, hold the side button on your Apple Watch. Slide to turn the watch off and then turn it back on. This should fix the pairing issue.
If restarting your iPhone does not solve the problem, you may need to perform a hard reset. This process can erase all of your Apple Watch data and make it ready for pairing again. Before resetting your iPhone, check the Bluetooth settings on your Apple Watch. When the Bluetooth setting is correct, your iPhone will pair with your Apple Watch. If the pairing process is not successful, you may need to restart your Apple Watch.
Resetting network settings on your iPhone
If your iPhone is having trouble pairing with your Apple Watch, you may need to reset its network settings. To do this, go to Settings > General > Reset and tap Reset Network Settings. Follow the on-screen instructions. Alternatively, you may have an older version of iOS and this could also be the cause of the problem. To update your iPhone, visit the Apple website. Once the update has finished, you can try resetting your network settings again.
Resetting your iPhone will clear all the settings for your network, including Wi-Fi passwords. If you've had network problems with your Apple Watch in the past, resetting the settings on your iPhone can fix the problem. Ensure you have saved all network passwords in the Notes app before beginning the process. Once you've done this, open the Watch app on your iPhone. Click on the General tab. From the menu, select Reset. Tap on "Erase All Content and Settings." If prompted, enter your passcode.
Resetting Bluetooth settings on your iPhone
If the pairing with your Apple Watch is causing frustration, resetting the Bluetooth settings on your iPhone might be the answer. After all, your Apple Watch relies on Bluetooth to connect with your iPhone. To do this, open Settings and tap on Bluetooth. Alternatively, you can open Control Center and go to the Bluetooth section. Tap the Bluetooth option and a gray button will appear beside it. If the button is gray, tap on it to turn it green. This will remove all devices that are connected to your iPhone.
Sometimes, the iPhone and Apple Watch will not pair because of a software issue. Depending on the operating system of your iPhone, it may be running on an outdated version of iOS. Plug your iPhone into a charging cable and connect to a Wi-Fi network to perform an update. Then, open Settings on your iPhone and tap General -> Software Update. Once there, tap Download and Install Now.
Restarting your Apple Watch
If you've experienced difficulty pairing your Apple Watch with your iPhone, it may be time to restart your watch. To do this, press and hold the Digital Crown or side button on your Apple Watch. Next, open the Settings app on your iPhone and scroll down to "General." Tap "Reset" at the bottom of the screen. The watch will reboot a few times, then return to the setup screen. Now, you can either sell or regift your watch, or continue troubleshooting.
Sometimes your Apple Watch won't pair with your iPhone if it's in Airplane Mode or Behavior. If you've encountered this problem, it's time to restart your Apple Watch. To do this, simply hold down the Side button until the Power Off slider appears, and then drag it to "off". Once the power-off slider has been reached, wait a few seconds for the Apple logo to appear. After this, try pairing your Apple Watch manually.
