I need a nudge:
My current phone situation is a Pixel 3 on Verizon, but I also have Google Voice. So I have an underlying number with Verizon (857 area code) that used to be my phone number to the world at large, but when I started using Google Voice I got a new number (617 area code) with that, and got everyone I know to start using that instead, and most people don't even remember that I had the older 857 number.
I'm not sure why I still have Google Voice at this point. The visual voicemail was cool but everyone seems to have that now. I like being able to search my text messages, and to be able to text people from my computer. But I don't use the "ring several phones with one number" feature anymore because I only have my mobile phone. The blocking and screening features are occasionally useful, but it seems like those are also widespread now. And it's always been behind on other things. I couldn't text MMS for a long, long time so people would send me pictures and they'd just go into the ether, and people would think I was rude for not responding. That all works now, though I still think my texts don't go through every so often.
Meanwhile Verizon has gotten very pricey so I've been curious about switching to Google Fi, since I'm mostly on WiFi either at home or at work.
It looks like I can port my 617 GV number to Fi so that's not a problem. But how do texts and voicemail work on Fi? Do they use Google apps? Google seems to have gone through a number of messaging apps lately (remember Hangouts?) and I don't know where they've settled.
