GL-AP1300-LTE unable to send sms

Hello,

With a functional sim card, I can surf in 4G TLE, but I can’t send SMS from the web interface.
SMS message are well added in /tmp/spool/sms/outgoing.
But smsd refuses to start because it is not configured.

There was 1 error while reading the config file:
2021-02-27 23:44:07,2, smsd: There was 1 error while reading the config file:
- Problem in configuration: [GSM1], [default] and [GSM*] are all missing.
2021-02-27 23:44:07,2, smsd: - Problem in configuration: [GSM1], [default] and [GSM*] are all missing.
There was 1 major problem found.
2021-02-27 23:44:07,2, smsd: There was 1 major problem found.
Cannot start. See the log file for details.
2021-02-27 23:44:07,2, smsd: Smsd mainprocess terminated.

$ cat /etc/smsd.conf
#
# Description: Main configuration file for the smsd

devices = GSM1
incoming = /var/spool/sms/incoming
outgoing = /var/spool/sms/outgoing

receive_before_send = no
autosplit = 3
logfile = 1

# Uncomment (and edit) this section to allow smsd to start:

#[GSM1]
#init = AT+CPMS="ME","ME","ME"
#device = /dev/ttyUSB0
#incoming = yes
#pin = 0000
#baudrate = 115200

The issue is still present after a reset.
I’m running version 3.105 and in autoconfiguration.
Can you fix this problem or give us a workaround?

Br,

Up. It’s really a blocking problem.

Seems the modem can only send message via 2G network.

So if your SMS is running on 4G LTE (i.e. VoLTE), you may not be able to send messages.

It is not a problem of smsd
