hi all i have a new TRB140 good Hardware but i cant send SMS.
I tried 2 simcards. SMSC are good.
Receive SMS good. Firmware=[TRB1_R_00.07.13.4]
Internet work fine but
Over gsmctl -S -s “+49170494342 TESTSMS”
[gsmctl_send_sms:22] error: ERROR: Failed to parse response
Any idea?
Hello,
Could you first confirm whether the SIM cards you’re using allow SMS sending as part of their plan and whether you’ve successfully tested sending SMS with them directly from a mobile phone?
Also, please make sure that the VoLTE option under Network → Mobile → Connection is set to On. After adjusting this setting, save and reboot the device and test again.
If the issue persists, for testing purposes, you could try replacing the “+” symbol in the recipient number with two zeros (00) — for example:
0049170494342 instead of +49170494342
Additionally, there’s an alternative method for sending SMS messages via the API you might want to try through CLI:
api post /messages/actions/send '{"data": {"number":"+XXXXXXXXXXX","message":"TESTSMS","modem":"2-1"}}'
Note: The
modemparameter might differ on your TRB140. You can check your modem’s correct ID by running:
cat /etc/board.json | jsonfilter -e '@.modems[0].id'
or by reviewing the /etc/config/network configuration under the config interface 'mob1s1a1' section (look for the option modem line).
Let me know how it goes.
Best regards,
hi thx for quick help,
1.the Sim Cards are allow to send SMS. I test it on phone work perfect
2. VoLTE is ON
3. With gsmctl -S -s “0049170494342 TESTSMS"
[gsmctl_send_sms:22] error: ERROR: Unknown error (errno:1)
4.Result: {“http_body”:{“success”:false,“errors”:[{“source”:“Message sending”,“code”:2,“error”:“Failed to send message”,“section”:“send”}]},“http_code”:422}
5. modem is 3-1 in TRB140
What is also interesting is that it outputs the result under one second
Thank you for the update and providing additional helpful information. Could you confirm whether the mobile data connection with the operator is established and the correct APN is selected? Also, please provide a screenshot from the Status → Network → Mobile page, with any sensitive/private information hidden (e.g., public IP, IMEI, ICCID, etc.). Furthermore, for testing purposes, try sending SMS through WebUI through Services → Mobile Utilities → Messages page, Send Messages tab. I assume if it is related to the issue with modem itself, it shouldn’t allow sending SMS via WebUI as well.
The Correct APN is selected the Internet works fine.
Over Service/MobileUtilites/Messanges pages ist same Problem (Failed to send Messages).
There is one thing I don’t understand. If it’s a problem with the modem, why can I receive SMS without any problems

Hello,
Having a similar issue with both TRB140 & TRB42 and both on Firmware: TRB1_R_00.07.14. I have other TRB142 units on the same Firmware.
The odd thing is that I can recieve sms and my data connection is fine; I connect via Wireguard.

Hi after a few hours of searching I found something. The gateway has problems with which mobile phone standard it is connected. With 2G, SMS sending works perfectly. In any case, a bridging solution is to switch the whole thing to 2G. Thx for help Marynas
