The Access Point Network, also known as the APN, is the configuration your cell phone service provider assigns to your device to connect and use to the mobile network. If you change providers or your provider assigns your account a different APN, you can create a new APN on your Samsung Galaxy to connect to the mobile network. You may also need to manually create an APN to configure your MMS service and other apps that access the Internet, depending on your cell service.
