Hello, I’m using Raspbian and the modem is connected with the MC AirPrime development kit.
at+cops: 0,0,“Verizon Wireless”,7
at+cgreg: 0,1
at+csq: 22,99
After trying to send SMS,
at+cmgf=1
OK
at+cmgs=""
The prompt skips a lot of lines and returns
+CMS ERROR: 300
I’ve verified that the SIM works by sending & receiving SMS on an Android. What could be causing the error?
