Welcome back and I do hope you had an excellent trip. In this case the next step woudl be a master reset of your phone. Have you backed up the item to your computer or Verizon cloud recently?

I did a factory reset and that did not resolve the issue. I have also shut the phone down multiple times and reinserted the SIM with the phone off
What is the network mode setting of the phone? It should be on CDMA/LTE mode and not Global or GSM mode.
