Properties for device type modems

Properties for device type modems:

GSM/CDMA modem configuration is only supported for the NetworkManager
backend. systemd-networkd does not support modems.

Requires feature: modems

apn (scalar) – since 0.99

Set the carrier APN (Access Point Name). This can be omitted if
auto-config is enabled.

auto-config (bool) – since 0.99

Specify whether to try and autoconfigure the modem by doing a lookup of
the carrier against the Mobile Broadband Provider database. This may not
work for all carriers.

device-id (scalar) – since 0.99

Specify the device ID (as given by the WWAN management service) of the
modem to match. This can be found using mmcli.

network-id (scalar) – since 0.99

Specify the Network ID (GSM LAI format). If this is specified, the device
will not roam networks.

number (scalar) – since 0.99

The number to dial to establish the connection to the mobile broadband
network. (Deprecated for GSM)

password (scalar) – since 0.99

Specify the password used to authenticate with the carrier network. This
can be omitted if auto-config is enabled.

pin (scalar) – since 0.99

Specify the SIM PIN to allow it to operate if a PIN is set.

sim-id (scalar) – since 0.99

Specify the SIM unique identifier (as given by the WWAN management service)
which this connection applies to. If given, the connection will apply to
any device also allowed by device-id which contains a SIM card matching
the given identifier.

sim-operator-id (scalar) – since 0.99

Specify the MCC/MNC string (such as “310260” or “21601”) which identifies
the carrier that this connection should apply to. If given, the connection
will apply to any device also allowed by device-id and sim-id
which contains a SIM card provisioned by the given operator.

username (scalar) – since 0.99

Specify the username used to authentiate with the carrier network. This
can be omitted if auto-config is enabled.
