I think it's time to find a new carrier

I have phone service. Sort of. Phone calls that do come through have no caller ID, even calls from people in my contacts list.

When I try making a phone call, 95% of the time, it instantly disconnects me. "Phone unavailable", "Disconnected", and "Service Unavailable" are typical errors that the phone app shows. Phone calls to me go straight to voicemail 99% of the time.

WiFi calling doesn't help, it's still going straight to voicemail. My freaking voicemail has like 9 messages in it and it's full.

Text messages and data still work just fine while the phone part is completely broken.

I have a phone that isn't locked to verizon, so it's time to leave verizon forever.

Any suggestions for carriers that don't actually suck when it comes to, you know, their service?
