Debugging mobile data connection

Hardware Librem 5
1

Hello,

My mobile data connection is not working for me.

And frankly I am a bit lost where should I look for information on this?

How does the modem shows up in linux, where can I find if there is an IP associated with it.

Any links to some gsm + linux docs would be helpfull.

@dos ping! :point_up:

I found some information from ArchLinux wiki since im a noob with GSM modems ( But I used to have a BBS quite a few years back :wink:

here is the output of ModemManager service

Does voice call work?

Ultimately I would expect that ifconfig or equivalent would answer that question. However a lot of things have to work before worrying about an IP address.

The problem appears to be ā€œmultiple-connection-to-same-pdn-not-allowedā€ but I donā€™t know what that means.

I donā€™t have voice calls enabled yet on that SIM cardā€™s service.
But it seems to work if I try to place a call I get a message saying that my plan does not support voice calls.

As for ifconfig nope there is no IP address on the interface.

Did you configure APN correctly?

I just tried for the first time and I think I managed to get data to work for a second after setting the APN and rebooted the phone. And then it did not work anymore after a minuteā€¦
Battery is now finished and I think I need to get SIM for testing so I donā€™t need to swap them back and forth.

I found one helper here:
https://developer.puri.sm/Librem5/Development_Environment/Boards/HowTo/Data_Connections.html?highlight=apn
But I Have not used these instructions myself.

Great thanks I will try that possibly later today.

But yes I configured APN in the settings GUI, but I found that there is a low number of settings. Usually the APN I am uused to have more settings, not only the hostnameā€¦

like this

APN: mobile.bm
MMSC: http://mms.mobile.bm
MMS proxy: mmsproxy.mobile.bm
MMS port: 80
APN type: default,mms,supl

Here is where I am at the moment when I follow the howto on developer.puri.sm

root@pietro:~# mmcli -m 0 --simple-connect=" apn=mobile.bm"
error: couldn't connect the modem: 'GDBus.Error:org.freedesktop.libqmi.Error.Protocol.CallFailed: QMI protocol error (14): 'CallFailed''```
