Questions[modem-manager](ubuntu)

When I run ModemManager --debug on the terminal, I get this output.

Running mmcli -L gives me:

/org/freedesktop/ModemManager1/Modem/0 [huawei] E3372

And running mmcli -m 0 gives me this output.

When I try to start modemmanager by sudo /usr/sbin/ModemManager, I get:

ModemManager[9099]: <info> ModemManager (version 1.10.0) starting in system bus...
ModemManager[9099]: <warn> Could not acquire the 'org.freedesktop.ModemManager1' service name
ModemManager[9099]: <info> ModemManager is shut down

I've been trying all the solutions on Google but to no avail. Any help is greatly appreciated!

How do I establish and IP connection to the WWAN of a Sierra Wireless MC7354?

I have a system with a Sierra Wireless MC7354 modem running Ubuntu 18.04.

ModemManager can see and control the modem.

$ mmcli --modem 0

returns lots of great information. (That's how I know the modem is an MC7354.)

Shows that the modem is connected to the internet (?).

How do I establish a connection on Ubuntu to use this interface?

How do I establish an IP connection to this device?

Thanks for the help!

I install modem manager Gui.

Everything works fine except USSD option.

I get this error Error picture

then I try the command line

mmcli -m 0 --3gpp-ussd-initiate="*222#"

but I get same error.

error: couldn't initiate USSD session: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Unsupported: Operation not supported.'

Can anyone help me to send ussd request?

Using wv dial I am able connect to the network. I have a need to use the Modem manager and dbus modem-manager interface.I am a novice using modem manager. This is how I configured modem manager.

I have multiple 3G USB based Modems. I would like them to keep connected simultaneously, NOT necessarily aggregating their bandwidth; a separate intelligent application would manage their utilization effectively.

However I am running into problem of setting up proper routes for the ppp0,ppp1 interfaces: when one of them connects, other's entries in the routing table get updated so it is no more usable. If I reconnect the second one, it would override the first one's routing entries. If I do it over and over, sometimes both of them's entries disappear while in rare cases the two work well.

I have tried it both using NetworkManager as well as WVDial but issue pops up in both of these. Perhaps both of them use same PPP dialer at the backend and thats why this issue appears.

What is the proper solution to make them work together? In the long run, I'd also like them to automatically dial in once USB gets connected.
