The waves may all work, but I'm still on my unlocked p2xl on Android 10. My unlocked device never had her VoLTE or will preferred calling. It seems like there is another service I miss out on, but it's been so long that I studied and fought the issue that I forget.
I did some changes with solid explorer to get wifi calling to kick in after a call begins, but I can't select it to be always preferred. Verizon said it shouldn't matter. People on this site with the same setup said they didn't have any issues and didn't have to do anything special at all, but there were some just like me too. For these reason alone I am very hesitant to get an unlocked phone anymore. I'll miss AdAway and viperfor Android, but besides those and 2-3 other things rooting seems stupid anymore. It was in 2017 when I did it to this phone.
The point being, Verizon/unlocked version on the vzw network DOES matter sometimes
