According to a technician at Verizon, he looked on Google's system (they must have some type of access to see issues) and said that he found ONE of these issues there, and it was corrected with a new SIM card with the existing Pixel 3. I find it a bit fishy...the amount of people having the issue that I've found on forums (my wife's brother is having it as well, but he thought it was due to the fact that he moved from Verizon to T Mobile and thought it was just the T Mobile network and is just dealing with it), and very little from Google on truly acknowledging it. If they did...they would probably be losing a ton of $$$ due to people not purchasing it.
It would be better for everyone impacted if it was a known issue which would mean Google has documented it and no fix is available yet but possibly working on it.
