Try AT+CPIN? . If that also gives error, try with ttyusb2 .

ReYuki · 2024-09-02 14:14:16

output on ttyUSB2:

OK

++CSQ: 99, 200

++HDRCSQ: 99, 200

it different from ttyUSB0, it print something like HDRCSQ and CSQ frequently to the terminal.

CSQ relates to signal quality and 99 appears to mean : not connected .

As it's the signal that's used for contacting 911/112 (or whatever emergency number your country uses) , it should not be impacted by the presence of a simcard.
Since usb0 didn't show it, it does seem likely that's the port we need .

What does AT+CSQ report for usb0 ?

ReYuki · 2024-09-02 15:34:36

ah, but it also printed on usb0:

AT+CSQ
+CSQ: 99, 200

OK

but it wasn't automatically printed on certain intervals like usb2 does.

That suggests some initialization is needed.

Often those are modem / provider / network specific , may be tricky to find them

What provider do you intend to connect with in which country ?
What standard do they support ( GSM 1,2,3,4,5 )?
GSM 1 is rarely used nowadays, support for 3 is vanishing fast and 2 is also being dropped in many areas.

Yeah, unfortunately I can't find proper settings related to the carrier config on the internet

I tried to connect with an XL SIM card from Indonesia.

It seems my device only supports 2G and 3G:

Product: CDMA 1x/EVDO Rev.A Device

and the operator supports 2G and 3G as well. I've checked from my mobile phone and selected only 2/3G

maybe a different approach will work better.

What does mmcli -L output now that the modem ports are seen/configured ?

ReYuki · 2024-09-03 10:34:06

mmcli still not able to detect the presence of modem:

[root@ASUS reyuki]#  mmcli -S
successfully requested to scan devices
[root@ASUS reyuki]#  mmcli -L
No modems were found
[root@ASUS reyuki]#

I think I'll put my attempt with the modem on hold for now and focus on something else. After all, it's an old modem, and I doubt it has good functionality or compatibility. I was just trying to see if I could reuse it for SMS purposes. Nice try, though.

By the way, do you have any recommendation for working modem that compatible for all phone carrier? I just need it for SMS purposes.

It's been many years since I used one.

People that need flexible internet access are now typically given a smartphone that functions as a wifi hotspot.
There are also hub devices that work the same way.

A downside of those is that they are usually locked to a specific provider.
