driver provides support for USB MBIM
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.
Required configuration parameters like PIN and APN have to be set with
. 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.
The following devices should work:
- Ericsson H5321gw and N5321gw
- Medion Mobile S4222 (MediaTek OEM)
- Sierra Wireless EM7345
- Sierra Wireless EM7455
- Sierra Wireless EM8805
- Sierra Wireless MC8305
Universal Serial Bus
Communications Class Subclass Specification for Mobile Broadband Interface
driver does not support IPv6.
Devices which fail to provide a conforming MBIM implementation will probably be
attached as some other driver, such as
