SIM7000A will not send a SMS to itself

Conclusions for the benefit of readers:

1. The SIM7000A can not send itself a SMS. The sendSMS will return successfully but the SMS will not be sent.

2. I lifted the SIM7000 initialization code from the LTE_Demo Example "setup" starting at:
Serial.println(F("Modem basic test"));
through
printMenu();
and made it a subroutine = Botletics_SIM7000A().


Then created a restart routine to be called as needed:

void Botletics_Reset(void) {
Serial.println(F("Executing Botletics_Reset"));
Serial.println(F("Setting modem.setFunctionality(6)"));
modem.setFunctionality(6); // Restart the module
delay(7000);
Serial.println(F("Executing Botletics_SIM7000A via Botletics_Reset"));
Botletics_SIM7000A();
}
