gcauilan Pixel 7 Pro with stock OS works fine with my carrier, except for the 5G band.
Oh I thought that what you said earlier meant that it worked with 5G. 314random is correct, it's about Google supporting other networks, not the other way around.
Google's website indicates that other unsupported networks may work, but there's no guarantees.
Unlisted carriers’ 5G networks may or may not work with Pixel phones.
Pixel phones work with all major carriers. But not all Pixel 7 Pro, Pixel 7, Pixel 6a, Pixel 6 Pro, Pixel 6, Pixel 5a (5G), Pixel 5 and Pixel 4a (5G) phones work on all 5G networks. Check with your carrier to make sure your phone works on its 5G network.
Hopefully what your carrier said is correct about their 5G working with Pixels!
