Hi,
for certain SIM cards (Vodafone Germany) and in certain Systems (ie.
Lenovo t460s) ModemManager seems to have trouble detecting the modem.
We have observed this for a couple of those combinations. Other SIM
cards seem to work fine and other thinkpad models aren't affected either.

Hi,

Hello List,
during connect the ModemManager debug logs show a List of provisioned
contexts. I assume that those are stored on the sim or in the modem
itself. Is there a way to query this list via the dbus api?

Hi,
In src/mm-bearer-mbim.c: ip_configuration_query_ready()
the bearer will set IP_METHOD_DHCP if ipv4dnsservercount is zero,
it does so regardless of any present IP configuration (which is visible
in the bearer object).
Unfortunately some (or all?) mbim modems do not support DHCP, and I have

Hi list,
I'm dealing with a Sierra Wireless EM7455 as used in Lenovos T460s.
For this modem the mbim driver attaches and works well (ie the sim can
be unlocked) until I try to connect. It then fails during a "set
radio-state" command.
I tried mbimcli with --set-radio-state=on with the same resul
