I keep trying different things, I don't know if this will help anyone but I restored a backup to this rom to try some things.
I went in to settings/Network Connections/More Networks/VPN
I added a dummy VPN, I just named it "test" and had to put in s server in order to save it (I just typed "google.com").
After saving it I was able to go into apn settings and add a new APN.
I googled Verizon APN settings to get the settings. After I added them it let me save them (it didn't before).
I soft rebooted and the APN was there and in the Lockscreen it now said "Verizon Wireless" as my carrier.
But...
I still have no data, can't make a call, sent SMS or MMS, and still can't make a call.
So I rebooted (not soft boot this time) and the APN was gone
I still haven't given up yet but I don't know where to go next.
