Apple Watch 3 First Time Set Up - Iphone Not Connected To The Internet Error
Hello hoping someone can advise on this issue.
I have Apple watch series 2 paired with my Iphone 12 Pro Max, I purchased this used October 2023. My daughter wants an apple watch, I found a brand new still sealed Apple watch 3 which I've been trying to pair with her Iphone 12 mini, but no matter what I try the pairing fails at the point of updating the watch OS with error advising the Iphone is not connected to the internet.
I've tried all the fixes I can find here and online, such as connecting to 2.4ghz wifi, clearing connections on the phone, reset the watch, updating IOS etc etc. I've spend a full day researching and trying the various fixes.
I've tried pairing the watch with 3 Iphones, all running latest IOS, all fail at the same point.
From what I can determine the watch should be compatible, well it must be if I was able to pair series 2 Apple watch, Series 3 should also work right?
I initially thought this issue was because the watch has never been activated, maybe it's not compatible with newer IOS, but reading through the numerous threads on this topic it's not unique to new watches, or the series 3.
If anyone has any ideas over and above the documented fixes, I'm all ears!
Thanks
iPhone 12 Pro Max, iOS 17
