I normally run without problems with +CSMS and +CNMI set to zero.

AT+CSMS?
+CSMS: 0,1,1,1
OK
AT+CNMI?
+CNMI: 0,0,0,0,0

What do the following AT commands return?

AT$QCPDPIMSCFGE?
AT+QCFG="ims"

Here is the result, thanks for the help

AT+CGDCONT?

+CGDCONT: 1,“IP”,“orange.m2m.spec”,“0.0.0.0”,0,0,0

Please add these two AT commands, and see how you go:

I’m thinking it’s time to ask if there is later firmware for you to upgrade to.

Google is suggesting to me that Orange uses IMS for SMS transport, but your modem seems to lack that support.

My BG77 manuals suggest that you should have more IMS commands working.

A big thank you to everyone, the problem is solved, I am ashamed, but I will say it anyway, I have several prototypes on the way and I was not sending the SMS from the right phone number, shame on me.

And thank you for that update. It puts my mind at ease.
