@efa2e20e the 4g non VoLTe has been off since Dec31 2022 for Verizon.  We were told that the rest of the 4g network would be “slowly phased out”. With no date.  The thought was that customers using old hardware (iPhone 5/6 and older), would have time to upgrade.  However the new network here is unstable and cannot handle the volume.  I drop calls like crazy in the middle of town, when  I used to have service pretty much everywhere before the switch.
