Here's a scenario I'm wondering about how it would work:
I have a cousin, who is a Google PixL owner, and has no intention of switching to an iPhone. He has always been interested in an Apple Watch though.
If I were to add him to my Apple Family Family Sharing group, and he got an Apple Watch, what would happen with this new set up?
Would he get texts? I'm thinking no.
Any other downsides that I'm not aware of, or thinking of?
He could certainly receive iMessages via Apple ID. And pretty sure texts, too. That is more carrier dependent.
