Name and model of a modem / phone: SerialLink SLK-M200-LTE-AH Industiral 4G Modem
Interface: serial
I bought this modem that supports 2G, 3G and 4G to replace an old 2G only modem. While it works if I text my cell phone, testing has shown that if I send an SMS message from the modem, which is a US number, to a device with a Belgian SIM card (+32 country code), the SMS does not arrive. It is not a SIM problem as the old 2G modem would work fine. I assume I need a different setting or initialization but I have not been able to figure out what.
This is my configuration. The problem device is GSM3:
devices = GSM1,GSM2,GSM3
logfile = /var/log/smsd.log
loglevel = 5
umask = 027
eventhandler=/usr/local/bin/smsmysql.sh

GSM2 = /var/spool/sms/queues/GSM2
GSM3 = /var/spool/sms/queues/GSM3
[GSM1]
queues = modemname
device = @192.168.2.1:5000
# telnet_login = admin
# telnet_password = admin

[GSM2]
queues = modemname, MAIN
device = @192.168.2.3:5000
# telnet_login = admin
# telnet_password = admin
incoming = yes
max_continuous_sending = 30
check_network = 2
[GSM3]
queues = modemname
device = /dev/ttyS0
incoming = yes
max_continuous_sending = 30

This is the output from show_device_details:
