Huawei E3131

Hello everyone.

I'm facing a problem with the device on subject. I am using an up-to-date Arch install, and have installed usb_modeswitch (from the repositories).
I have looked all over the net for how to get this device recognized correctly, but what I'm seeing on my end does not match the information I've found online.
Here are some outputs to give you an idea of the problem (sorry about the WoT, I could nest this in a big code block to shorten it if you'd prefer):

mount

[...]
/dev/sr1 on /media/Mobile Partner type iso9660 (ro,nosuid,nodev,noexec,noatime,uid=1000,gid=100,utf8)

As far as I can see, the device gets recognized simultaneously as both network device and mass storage device, because when I plug it in I can find the devices /dev/TTYUSB{0,1,2}, the relevant modules get loaded and I get a new network interface wwan0, but I can also see the storage partition, as you can see from the mount output. I cannot get it to work with sakis3g, wvdial and NetworkManager (when tried from nm-applet).
I can see no difference when plugging it in after removing usb_modeswitch (and rebooting), so I'm afraid it's not working.
I couldn't find much info on a device that gets recognized directly with id 1506, but only several devices that, after getting "modeswitched", as result get recognized with id 1506; I would think that this would be a positive thing (no modeswitching required!) but sadly the modem doesn't work.

Thanks for taking the time to read this!

Re: Huawei E3131

Have you installed "modemmanager"? It is an optDep of networkmanager and is required for WWAN.

If you have, lets have a look at the output of

journalctl -b -u modem-manager

(and perhaps networkmanager as well)
