After weeks of use my SIM7000A stopped sending SMSs. I dropped back to the tried and proven "SMS_Response" example found on GitHub and it does the same: the SIM7000A receives SMSs sent to it, and replies that it successfully sent the response, but nothing is sent. I have reviewed my carrier's records and see the incoming messages received by the SIM7000 but there is nothing outgoing. I have searched and posted on the forum but the forum appears to be useless and dead as no one seems to be using it.
I have invested weeks of time into my project and I am desperate to know what is wrong.

Does sending texts work using the LTE_Demo sketch?

Thank you for responding.
Last night I powered down the Arduino and SIM7000, and disconnected the LiPo battery.
As per your question, I powered up and downloaded the LTE_Demo sketch. AND it works for incoming and outgoing SMSs, although the send reports back that it failed when it was successful (see my other thread about this issue).
I then downloaded the SMS_Response sketch and it also works for incoming and outgoing SMSs.
I then downloaded my weather station sketch and it also works for incoming and outgoing SMSs.
What does the LTE_Demo sketch do that the SMS_response sketch does not do? LTE_Demo appears to have initialized differently? Or did a good night of hardware sleep do something? Not likely.

As long as you have the same setup() settings, it should work just fine. Just make sure that you select the right network settings for it to auto-connect, because you're using T-Mobile instead of AT&T.

Yea looks like you're connecting just fine. I haven't worked with the T-Mobile network.
