Voice over LTE is how they do voice calls over a 4G/LTE cellular network. It is the way the majority of cell phones with 4G/LTE do voice calls these days if the phone has 4G/LTE service.
Years ago when I got my first smart (late starter) I signed up for 2gb plan. Ran out and up it to 4gb plan. Ran out again and up it to 8 gb and ran out. Then made the jump to 32 gb and came close (31gb) to running out. Final fed up went with the unlimited 75gb at LTE and 3G after 75gb. It is funny but I surfed more, played tons more movies and still ended using less than 12gb on the unlimited plan and rarely went over that unless I was on vacation for a week in that month. It is some kind of game the companies do to get to upgrade to larger usage plans. So we have a flip phone for just talking and a smart phone for internet.
The ADT contract must be worth a lot to Verizon for Verizon to keep postponing the 3G shutdown. I found some other articles that stated that Verizon has now set Dec 31, 2022 as the new date which is three years past when Verizon originally said 3G would shut down.
I would assume Verizon is shutting down 3G to free up space for more 4G and 5G. You would think 4G and 5G would be pretty important to Verizon's future revenue.
Yes, that is one of two reasons for finally killing off the 3G stuff...it frees spectrum (frequencies) for more current technologies, both to use and to trade, and also eliminates older gear that has to be maintained and takes up space. In many base station (tower) locations the "gear" takes up a lot of what is limited space, especially since a very large percentage of towers are shared with multiple carriers.

We have unlimited, but I still have my phone set to only ring if the caller is in my Contacts list. People tell me that my Voicemail box is full. It is because I've never used it, and don't intend to. That, of course, won't work if you answer your phone regardless of who calls, and use voicemail. It does work wonderfully, for cutting down on unwanted calls though.
Voicemails can be funny. For about 2 months I was getting one from a collection agency saying that they were going to court to attach my wages if I didn't contact them. At first they were robocalls and then it was a live person. Not sure where they got my number from but it was still funny. Sometimes they would try to act all nice and use the woman's first name, like "Marie, just call us and we can work this out" and other times it was "Mrs Jones, you need to call us now. Once we file the paperwork in court it's too late". Amazing how many lawyers do this kind of work. I assumed it was because they weren't very good at their job. With unlimited minutes I didn't really care but back in the day when I had a plan that limited me I could see how having a lawyer calling the wrong number repeatedly would be an issue.
Go unlimited and no more worrying. Surely your carrier would be happy to switch you over. They don’t like the old minute plans I don’t think.
I have a phone, but seldom use it. It has a pedometer app I use when I make my morning walk.
SWMBO pays for it so if I ever need help, I can call her.
