Press and hold the side button on your Apple Watch, and the shutdown menu will pop up. Now, use the Power Off slider to turn off your device and then power it back on by using the side button again. After rebooting your Watch, try re-pairing your Apple Watch Ultra and iPhone. Now, check if you are facing any connectivity issues.
3. Reset Your Apple Watch Ultra
Sometimes, an ordinary reboot may not do the trick, and your pairing issues may persist. So, you may have to take the extreme step- a factory reset. Navigate to Settings -> General in your Apple Watch and scroll to the bottom, then tap on the Reset option.
Doing this will erase all the content you have stored on your Apple Watch Ultra, but it could fix the pairing issues. After the factory reset, you will need to set up your Apple Watch as a fresh device on your iPhone.
4. Unpair and re-pair
If none of these steps work, you can unpair your Apple Watch Ultra using your iPhone. This could be of real help if your Watch is not connecting after a successful pairing.
However, just like resetting Apple Watch Ultra, this will also erase the content stored on your Apple Watch. You’ll use the Watch app on your iPhone to complete this procedure. After unpairing the two devices, you must re-pair them to see if your issue got fixed.
Whether you are unpairing your Apple Watch Ultra or you are doing a factory reset, you can still save the data to be erased by choosing the option to restore it from the backup.
