Hello World! The router is working with the Optimum Mobile SIM to send/retrieve data to the internet but the SMS feature doesn't work at all. Any ideas?
Which router (which model?) are you using?
GL-XE300 (Puli)
Which firmware version is in use?
Latest (4.3.23 Beta 2024-09-19) but reports as 4.0.0 in the web front end
root@GL-XE300:~# gl_modem AT AT+QGMR
EC25AFXDGAR07A01M1G_01.002.01.002
OK
How is your router connected to the Internet?
By cell phone? (If yes, which mobile provider?)
Optimum Mobile SIM Card
Which DNS server do you use? (The local one of your ISP? AdGuard Home? Another one?)
Default
opkg update
opkg install minicom
minicom -D /dev/ttyUSB2
Enable local echo to view entered commands:
CTRL+A then press E
AT+CMGF=1 and press Enter
AT+CMGS= "+phonenumber" and press Enter
> Write your message (it won't appear on minicom) and press CTRL+Z
+CMGS: 8
OK
quit
CTRL+A then press Q then Enter
I see the modem firmware release notes mentions SMS patches (e.g. Fixed the PSI error obtained from SIM card which caused the SMS sending failure) do you think installing this version EC25AFXGAR07A04M1G 01.009.01.009 is a good idea? I have version: EC25AFXDGAR07A01M1G_01.002.01.002 . This page doesn't have this particular firmware but I presume the instructions are the same.
yes. this is what bruce helped me with: (it basically forced the modem to register sms, i guess before it wasnt registering sms even though i could sms with the phone)

The issue is IMS/SMS service of the modem does not register in ISP.
AT brings the modem to register the IMS service:
AT+QCFG="ims",1
it’s the issue solved permanently in the modem, even if flash the router firmware, but do not flash the modem firmware or reset modem configuration.
