+ * Troubleshooting (requires qmicli and stopping ModemManager: systemctl stop ModemManager)
+  * Check system info. Note below the 'True Status' states 'limited-regional'. That usually means the device is registered for emergency services only. This has nothing to do with APN being wrong, it still needs a "full" proper LTE registration before you try with the APNs. Try to talk to Verizon/Provider support about the status of this account and see what they say.
