    mm_modem_get_device_identifier (MMModem *self);

Gets a best-effort device identifier based on various device information like model name, firmware revision, USB/PCI/PCMCIA IDs, and other properties.

This ID is not guaranteed to be unique and may be shared between identical devices with the same firmware, but is intended to be "unique enough" for use as a casual device identifier for various user experience operations.

This is not the device's IMEI or ESN since those may not be available before unlocking the device via a PIN.

MMModemLock handled by the modem, the

number of PIN tries remaining before the code becomes blocked (requiring a PUK) or permanently blocked.

The returned value is only valid until the property changes so it is only safe to use this function on the thread where `self` was constructed. Use `mm_modem_get_unlock_retries()` if on another thread.

#### Parameters

self | A MMModem. |

MMModemLock handled by the modem, the

number of PIN tries remaining before the code becomes blocked (requiring a PUK) or permanently blocked.

The values reported by `self` are not updated when the values in the interface change. Instead, the client is expected to call `mm_modem_get_unlock_retries()` again to get a new MMUnlockRetries with the new values.

#### Parameters

self | A MMModem. |

#### Returns

A MMUnlockRetries that must be freed with `g_object_unref()` or `NULL` if unknown.

[transfer full]

Since: 1.0

### mm_modem_get_max_bearers ()

    guint
    mm_modem_get_max_bearers (MMModem *self);

`mm_modem_get_max_bearers` has been deprecated since version 1.18. and should not be used in newly-written code.

There is no way to query the modem how many bearers it supports, so the value exposed in this property in all the different implementations is always equal to the one retrieved with `mm_modem_get_max_active_bearers()`, so there is no point in using this method.

Gets the maximum number of defined packet data bearers this MMModem supports.

This is not the number of active/connected bearers the modem supports, but simply the number of bearers that may be defined at any given time. For example, POTS and CDMA2000-only devices support only one bearer, while GSM/UMTS devices typically support three or more, and any LTE-capable device (whether LTE-only, GSM/UMTS-capable, and/or CDMA2000-capable) also typically support three or more.

#### Parameters

self | a MMModem. |

#### Returns

the maximum number of defined packet data bearers.

Since: 1.0

### mm_modem_get_max_active_bearers ()

    guint
    mm_modem_get_max_active_bearers (MMModem *self);

Gets the maximum number of active packet data bearers this MMModem supports without enabling multiplexing support.

POTS and CDMA2000-only devices support one active bearer, while GSM/UMTS and LTE/5GNR capable devices (including 3GPP+3GPP3 multimode devices) may support one or more active bearers, depending on the amount of physical ports exposed by the device.

                            gpointer user_data);

Asynchronously deletes a given bearer from the MMModem.

When the operation is finished, `callback` will be invoked in the

thread-default main loop

of the thread you are calling this method from. You can then call `mm_modem_delete_bearer_finish()` to get the result of the operation.

See `mm_modem_delete_bearer_sync()` for the synchronous, blocking version of this method.

#### Parameters

self | A MMModem. |
bearer | Path of the bearer to delete. |
cancellable | A GCancellable or `NULL`. | [allow-none]
callback | A GAsyncReadyCallback to call when the request is satisfied or `NULL`. |
user_data | User data to pass to `callback` . |
