I tried every other way mentioned in the blogs and post to update my apple watch 3 via iphone 12, but didnt worked. Everytime it prompted no internet, try again even though internet was flawless. I tried reseting network settings, hard reset etc and etc, but still back to square one. What clicked for me was quite very easy and is as below.
Solution :
- Reset your apple watch : Press crown and power button simultaneously until it switches off.
- If the apple watch was already paired , in the bluetooth section of your iphone , click on forget the device.
- Now , if your iphone is connected to the wifi network on 5G or if your phone has internet coming in as 5G , you need to change that to lower version by selecting a lower version wifi signal in your iphone. Reason , apple watch 3 doesnt support 5G and pairing/updating it over the same network will always prompt no internet.
- Now after selecting the lower wifi version in your iphone, connect to it.
- Switch on and pair your apple watch with your iphone.
- It will start the update post clicking on update now in apple watch app on the iphone.
Thanks
