GSM-based Mobile Broadband Settings

## Property Details

### The `“apn”` property

      “apn”                      gchar *

The GPRS Access Point Name specifying the APN used when establishing a data session with the GSM-based network. The APN often determines how the user will be billed for their network usage and whether the user has access to the Internet or just a provider-specific walled-garden, so it is important to use the correct APN for the user's mobile broadband plan. The APN may only be composed of the characters a-z, 0-9, ., and - per GSM 03.60 Section 14.9.

Owner: NMSettingGsm

Flags: Read / Write

Default value: NULL

### The `“device-id”` property

      “device-id”                gchar *

The device unique identifier (as given by the WWAN management service) which this connection applies to. If given, the connection will only apply to the specified device.

Owner: NMSettingGsm

Flags: Read / Write

Default value: NULL

Since: 1.2

### The `“home-only”` property

      “home-only”                gboolean

When `TRUE`, only connections to the home network will be allowed. Connections to roaming networks will not be made.

Owner: NMSettingGsm

Flags: Read / Write

Default value: FALSE

### The `“mtu”` property

      “mtu”                      guint

If non-zero, only transmit packets of the specified size or smaller, breaking larger packets up into multiple frames.

Owner: NMSettingGsm

Flags: Read / Write / Construct

Default value: 0

Since: 1.8

### The `“network-id”` property

      “network-id”               gchar *

The Network ID (GSM LAI format, ie MCC-MNC) to force specific network registration. If the Network ID is specified, NetworkManager will attempt to force the device to register only on the specified network. This can be used to ensure that the device does not roam when direct roaming control of the device is not otherwise possible.

Owner: NMSettingGsm

Flags: Read / Write

Default value: NULL

### The `“number”` property

      “number”                   gchar *

Legacy setting that used to help establishing PPP data sessions for GSM-based modems.

`NMSettingGsm:number` has been deprecated since version 1.16 and should not be used in newly-written code.

user-provided values for this setting are no longer used.

Owner: NMSettingGsm

Flags: Read / Write

Default value: NULL

### The `“pin-flags”` property

      “pin-flags”                NMSettingSecretFlags

### The `“sim-id”` property

      “sim-id”                   gchar *

The SIM card 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.

Owner: NMSettingGsm
