This will be my last comment. It's great to see you googled an answer. But what you've surmised from that google search, I'm sure is an attempt to prove that an iPad should be able to pair with an Apple Watch. Which is, after all, the entire point of this thread. The fact is an Apple Watch cannot, nor has it ever had a way to pair with an iPad. You did make a point previously that to make phone calls a device needs to have voice and data which iPhone has. iPad doesn't. That's what I mean by saying an iPad doesn't have a cellular radio like iPhone does.
Anything else is purely semantic and doesn't help anyone in this thread who simply want to know if they can pair an Apple Watch with an iPad. The answer is an emphatic NO, they cannot pair an Apple Watch with an iPad.
If anyone here is not happy about that, arguing with only other users, none of whom have anything to do with Apple, nor why Apple makes things work as they do, is a waste of time and pointless.
