@Whe3zy Verizon will probably never support the L5 even if it gets VoLTE. From my experience they dislike supporting unlocked phones at all.
I noticed you responded to my comment in the other thread, so I’ll update that advice here. It used to be the case that you could activate a SIM card in an approved phone, switch it, and Verizon would be none the wiser. I tried doing this with my Pinephone though and after about a week of use my cell connection was changed to a data-only connection. At the same time, I got an email from Verizon saying my “account changes” had been processed. I logged in to my account and had a notification saying “here are the capabilities of your new device” with some other information, but long story short they realized something was up and disabled the phone functionality until I put the card back in my original phone.
