NM_SETTING_GSM_BANDS_MAX macro indicate the maximal value that can be used as the allowed frequency bands (“allowed-bands” property).

## Property Details

### The `“allowed-bands”` property

      “allowed-bands”            guint

Bitfield of allowed frequency bands. Note that not all devices allow frequency band control. Permitted values are those specified by NMSettingGsmNetworkBand.

`NMSettingGsm:allowed-bands` has been deprecated since version 0.9.10 and should not be used in newly-written code.

No longer used. Band setting should be done by talking to ModemManager directly.

Flags: Read / Write / Construct

Allowed values: <= 16383

Default value: 1

### 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.

Flags: Read / Write

Default value: NULL

### 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.

Flags: Read / Write

Default value: FALSE

### 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.

Flags: Read / Write

Default value: NULL

### The `“network-type”` property

      “network-type”             gint

Network preference to force the device to only use specific network technologies. The permitted values are `NM_SETTING_GSM_NETWORK_TYPE_ANY`, `NM_SETTING_GSM_NETWORK_TYPE_UMTS_HSPA`, `NM_SETTING_GSM_NETWORK_TYPE_GPRS_EDGE`, `NM_SETTING_GSM_NETWORK_TYPE_PREFER_UMTS_HSPA`, `NM_SETTING_GSM_NETWORK_TYPE_PREFER_GPRS_EDGE`, `NM_SETTING_GSM_NETWORK_TYPE_PREFER_4G`, and `NM_SETTING_GSM_NETWORK_TYPE_4G`. Note that not all devices allow network preference control.

`NMSettingGsm:network-type` has been deprecated since version 0.9.10 and should not be used in newly-written code.

No longer used. Network type setting should be done by talking to ModemManager directly.

Flags: Read / Write / Construct

Allowed values: [-1,5]

Default value: -1

### The `“number”` property

      “number”                   gchar *

Number to dial when establishing a PPP data session with the GSM-based mobile broadband network. Many modems do not require PPP for connections to the mobile network and thus this property should be left blank, which allows NetworkManager to select the appropriate settings automatically.

Flags: Read / Write

Default value: NULL

### The `“password”` property

      “password”                 gchar *

The password used to authenticate with the network, if required. Many providers do not require a password, or accept any password. But if a password is required, it is specified here.

Flags: Read / Write

Default value: NULL

### The `“password-flags”` property

      “password-flags”           guint

Flags indicating how to handle the “password” property.

Flags: Read / Write

Allowed values: <= 7

Default value: 0

### The `“pin”` property

      “pin”                      gchar *

If the SIM is locked with a PIN it must be unlocked before any other operations are requested. Specify the PIN here to allow operation of the device.

Flags: Read / Write

Default value: NULL

### The `“pin-flags”` property

      “pin-flags”                guint

Flags indicating how to handle the “pin” property.

Flags: Read / Write

Allowed values: <= 7

Default value: 0

### The `“username”` property

      “username”                 gchar *

The username used to authenticate with the network, if required. Many providers do not require a username, or accept any username. But if a username is required, it is specified here.

Flags: Read / Write

Default value: NULL
