Hello… I’m trying to use an FX30S to send SMS messages via a utility that’s part of an industrial control system that I manage. The FX30S has an active AT&T SIM card in it. The interface on the control system sees the FX30S; it reports back the manufacturer, model number, SMSC number, etc. When the utility generates an SMS, it reports that it was successfully sent, but it’s never received at the destination.
I opened up TeraTerm to try and send one manually from there using the AT+CMGS, and the command SEEMS to be accepted, but again, no SMS on the receiving end. I’m pretty new to all of this, looking for suggestions. Screenshots attached of what I was seeing. Thanks!
