An Access Point Name (APN) configuration for a carrier data connection.
The APN provides configuration to connect a cellular network device to an IP data network. A carrier uses the name, type and other configuration in an APNSetting to decide which IP address to assign, any security methods to apply, and how the device might be connected to private networks. 
Use Builder to create new instances. /**
