I'm sure you all knew this worked like this but I didn't. I forgot my iPhone at home today. When I got to work my Apple Watch connected to wifi and I'm getting my iMessages and I can reply to them with Siri. Somethings update (like stocks) but others do not (it can't find location). --- Post Merged, Jan 5, 2016, Original Post Date: Jan 5, 2016 --- And Apple Pay works. Which I kind of knew but hadn't actually done without my phone. I wonder how many coffee shops in my neighborhood would now work for me without my phone since I've synced with their wifi in the past.
