Access point name (APN)

The access point name (APN) is a network identifier that the device uses to connect to the packet data network of the cellular network. You have the following options:

Default APN: Most carriers automatically configure the correct APN.
Manual configuration: If needed, you can configure the APN through Kconfig:
```
CONFIG_PDN_DEFAULT_APN="Access point name"
```

You typically configure the APN in the following scenarios:

Using a custom or private APN.
Connecting to specific network services.
Working with mobile virtual network operators (MVNOs).

Note

In most cases, the default APN provided by the carrier should work without additional configuration.
