I'll let Bjorn address this specific EPIPE issue.

But for the above stuff, note that MBIM modems often (always?) do *not*
support DHCP on the net interface.  You'll get best results by reading
the IP configuration using the MBIM protocol and assigning those
details to the device.  ModemManager will retrieve those for you, but
it does not do IP configuration, instead leaving that up to something
like NetworkManager or custom scripts.

mbim-network also does not set the IP configuration for you, since a
lot more is involved than just assigning the IP address to the
interface.  (eg, should the DNS servers be written to resolv.conf? 
what if something else is managing resolv.conf?  Should a default route
be added through the interface?  what if something else is managing the
default route or you don't want that to happen?)
