@Tkenoras - this message can sometime happen, unfortunately; it has happened to me too. The account should eventually reset itself and the message should discontinue.
If your call completes, ignore the message.
If the call does not complete try to perform a reset of the device's network settings.
Perform a Reset of your device's Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, VPN and APN settings, and connected Bluetooth devices that you've used before.
Iphone:
To Reset Network Settings, begin by opening the Settings app. Next, tap General -> Transfer or Reset iPhone -> Reset -> Reset Network Settings. and enter your passcode.
Your iPhone will reset network settings and restart itself.
android:
Find and tap Settings > System > Advanced > Reset options > Reset network settings.
If still issues and not able to make outgoing calls, go to the bottom of the Community page to submit a ticket with Customer Support using the SIMon Chatbot option.
