I did get my MVNO to file a ticket with Verizon. Maybe they'll wake up and fix it.
Just got this from my MVNO:
Twigby has contacted our network partner in regards to the difficulty you are having with your service.
They did confirm that customers in your area could be experiencing problems with the network at this time. The network team is aware of the problem and working to resolve it in a timely manner.
Although we do not have a specific estimated repair time, you may want to turn airplane mode on and then back off once each hour so that the phone is forced to reconnect with the tower.
We will update you if we are provided any additional information.
We apologize for the inconvenience.
Sincerely,
Twigby Customer Support
