I came across this article on Ars Technica about Android 8.1 features. One thing noted near the end of the article is that AT&T's VoLTE will work in 8.1. Quote below:
"I'll go out on a limb and say that while Voice over LTE (VoLTE) on AT&T did not work on the Pixel 2 on Android 8.0, it should now work on 8.1. In the vendor image, I see an MBN configuration file has moved from ".../ATT/Non_VoLTE" to ".../ATT/VoLTE."

I've been considering this idea as well. I have my son's phone (Nexus 5X) on Project Fi now, partly because AT&T charged more for another line. I also wanted to try out Fi for myself. When I do pick up a Pixel 2 XL (c'mon panda!), I may make the jump there, and leave the wifey at AT&T and her branded Note 8.

This makes me want to switch to Net10, TMobile, or Project Fi.
