+.Sh NAME

+.Nd USB Mobile Broadband Interface Model (MBIM)
+.Sh SYNOPSIS
+.Cd "umb*  at uhub?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for USB MBIM devices.
+.Pp
+MBIM devices establish connections via cellular networks such as
+GPRS, UMTS, and LTE.
+They appear as a regular point-to-point network interface,
+transporting raw IP frames.
+Once a connection is established,
+the device will automatically set an IP address
+and send out a nameserver proposal,
+which
+.Xr resolvd 8
+can act on.
+.Pp
+Required configuration parameters like PIN and APN have to be set
+with
+.Xr ifconfig 8 .
+Once the SIM card has been unlocked with the correct PIN, it
+will remain in this state until the MBIM device is power-cycled.
+In case the device is connected to an "always-on" USB port,
+it may be possible to connect to a provider without entering the
+PIN again even if the system was rebooted.
+.Sh HARDWARE
+The following devices should work:

+.It Ericsson H5321gw and N5321gw
+.It Fibocom L831-EAU

+.Sh EXAMPLES
+The following
+.Xr hostname.if 5
+example configures umb0 to set the APN to
+.Dq internet ,
+enabling data roaming,
+and obtaining an IP address using IPv6 stateless address autoconfiguration:

+.Sh CAVEATS
+Devices which fail to provide a conforming MBIM implementation will
+probably be attached as some other driver, such as
+.Xr umsm 4 .
