Will this work on Google Fi?
That definitely sounds like a yes.
Will it work internationally?
Best to check with your carrier.
Am I reading it right that all of these new Pixels have a full warranty from Google despite being released in 2018?
Must be why clicking on the warranty takes you to Google Support…
No need for the sarcasm, it’s just kind of surprising that Google would be giving a full warranty for an EOL device. I ordered a 3 XL on the basis that it says it comes with a full Google warranty, I just wanted confirmation is all.
Yes, the warranty is as stated. 
That’s crazy! Makes this a really sweet deal since Pixels are known to have reliability issues. Glad I jumped on it (I bought the white 64GB 3 XL that’s $220, there’s no forum thread for it)!
Did you register the item with Google? With computers, the warranty date is set as the sale date to the reseller and then resets when you register it. I’m wondering if it’s the same for phones.
If no luck, reach out to Woot! Customer Service and show them what Google Support told you.
From a browser, use the Woot! Customer Service form.
In the Woot! App, choose Account from the bottom navigation and then Support.
Note: Woot! Customer Service replies go to the email address on your Woot! account, not your Amazon login email if used/different.
To prevent anyone else’s further headache, if you’re going to use Google Fi on an unlocked Verizon Pixel, you will need a physical SIM card for it to work. The eSIM from an unlocked Verizon phone will not work with Fi.
I deleted my original comment about warranties. It took a few more hours with Google’s Customer Support to confirm that my new Pixel 3 purchased from Woot! was indeed under the one-year warranty. (The first customer support specialist was wrong.)
I purchased it in August 2021, but only set it up last week. The warranty must have kicked in during setup, because my device is covered until Sept 2022.
I was able to process a replacement through Google’s normal warranty process.
