An APN usually consists of two pieces of information, a network identifier and an operator identifier. The network identifier outlines the external network that your device will connect to, and the operator identifier outlines the mobile country code (MCC) and the mobile network code (MNC) for the specific mobile network operator it will use.
Here is how an APN is usually structured:

However, not all APNs follow this format, some are much more simple.
Access point names are structured like this to provide mobile network operators with all the information they need to:
- Determine which methods of security should be used.
- Determine which network the device needs to connect to.
- Assign the correct IP address to the device.
