Advice on buying a Pixel 3 (ATT)

FYI...Popped my at&t sim card into my pixel 3xl.

I was shocked also when I saw wifi calling working. Now I'm completely stoked about my 3xl. That was the only thing I would have missed coming from the Note 9.

I downloaded the visual voicemail app and now I have att visual voicemail.
 
It was a joint venture of responsibility that has been corrected on the 3. Unboxed, went to settings and turned on wifi calling...has worked ever since.
