Hi evryone,
I have the same problem with an TRB245.
In the WebUI even after a delete command, the SIM storage remained stuck at 9/10
root@TRB245:~# gsmctl -A 'AT+CPMS="SM","SM","SM"'
+CPMS: 9,10,9,10,9,10
root@TRB245:~# gsmctl -A 'AT+CMGF=1'
OK
root@TRB245:~# gsmctl -A 'AT+CMGD=1,4'
OK
root@TRB245:~# gsmctl -A 'AT+CPMS?'
+CPMS: "SM",9,10,"SM",9,10,"SM",9,10
root@TRB245:~# gsmctl -A 'AT+CPMS="ME","ME","ME"'
+CPMS: 0,255,0,255,0,255
root@TRB245:~# gsmctl -A 'AT+CGSMS=2'
OK
root@TRB245:~# gsmctl -S -s "+49151*** Test"
SMS sent: 1
@marius-machts Thanks. Tried, but without success, although a different error:
root@RUTX50:~# gsmctl -A 'AT+CPMS="SM","SM","SM"'
+CPMS: 7,30,7,30,7,30
root@RUTX50:~# gsmctl -A 'AT+CMGF=1'
OK
root@RUTX50:~# gsmctl -A 'AT+CMGD=1,4'
OK
root@RUTX50:~# gsmctl -A 'AT+CPMS?'
+CPMS: "SM",0,30,"SM",0,30,"SM",0,30
root@RUTX50:~# gsmctl -A 'AT+CPMS="ME","ME","ME"'
+CPMS: 0,127,0,127,0,127
root@RUTX50:~# gsmctl -A 'AT+CGSMS=2'
OK
root@RUTX50:~# gsmctl -S -s "PHONENUMBER Test"
[gsmctl_send_sms:22] error: ERROR: Request timed out
After resetting connection, the Failed to parse response returns:
From the behavior described, the router is able to receive SMS messages successfully, while sending SMS fails both from the WebUI and CLI with the following error:
ERROR: Failed to parse response
Since the same router can send SMS successfully when using a SIM card from another operator, this indicates that the router hardware and modem are functioning correctly. The issue is therefore likely related to operator-specific behavior or the response returned by the modem when attempting to send an SMS.
To investigate this further, we kindly ask you to provide the following additional information.
Please execute the following command via SSH and provide the full output:
gsmctl -A 'AT+CMGS="+<phone_number>"'
Network registration status: please run the following commands and share their outputs:
gsmctl -A 'AT+COPS?'
gsmctl -A 'AT+CREG?'
gsmctl -A 'AT+CGREG?'
SIM card details: please confirm with your operator whether the SIM card supports outgoing SMS from data devices (routers/modems) . Some IoT or data-only SIM profiles allow receiving SMS but restrict sending.
root@RUTX50:~# gsmctl -A 'AT+CMGS="+351<number>"'
+CMS ERROR: 304
root@RUTX50:~# gsmctl -A 'AT+CMGS="<number>"'
+CMS ERROR: 304
root@RUTX50:~# gsmctl -A 'AT+COPS?'
+COPS: 0,2,"26806",13
root@RUTX50:~# gsmctl -A 'AT+CREG?'
+CREG: 2,1,"BEBE","004AD1F",13
root@RUTX50:~# gsmctl -A 'AT+CGREG?'
+CGREG: 2,0
Regarding the SIM card SMS support, the operator claims that there is no blocking. Furthermore, I can send SMS using the same SIM cards from a Quectel RM520N-GL modem.
