I am using an Arduino Uno and SIM7000A shield. The setup has been tested and is working, except I cannot receive SMS messages when sent from the Arduino Serial Monitor. I have tried entering the country code of 1 by itself and/or with a + in front. No luck. Used the S command to establish a pass though tunnel and AT+COPS=1,2,“310410” to use AT&T as the carrier. Still nothing.
I setup a Hologram Data Route to re-route the SMS. Sent myself a SMS from it to get the alternate phone number. Used that in the Serial Monitor and received SMS on my cellphone.
Stumped since all other features are working. Would rather not re-route since I am specific on the messages I would like to received via SMS. Thanks.

Added Serial monitor data. 3 sections show results. X’s represent my phone number and IMEI.
