For how to set Access point name 3G/4G LTE as mentioned earlier, this is one of the best options for implementing APN on your cellphone, and can also be applied to tablets or PCs.

How APN Work

For how this APN works, it is usually used to provide an IP address that is used to identify network devices, so the network operator will check that your device type matches the type of connection made.

The access point name itself has some important information that is taken into consideration by the internet service provider operator, namely in the form of username authentication, passwords, authentication, profiles and others.

Types of Access Point Names

There are two most common types of Access Point Names, including public Access point names and private Access point names and are distinguished again by using IP addresses, namely static IP and dynamic IP:


A public access point name is a type of access point name that is provided by the operator for network connections in general. Usually what type of public is most often used by most people.


This type of public Access point name with a static IP is almost the same as a public Access Point Name but has a static IP.

Access Point Name PRIVATE

With Access point name private, devices can connect devices to the internal Access Point Name network using a gateway or VPN.


Gateway or VPN assigns a static IP to the device.

Access Point Name Structure

The access point name does not stand alone because it has two structures, namely the network identifier and the operator identifier.

This network identifier is useful for identifying the connected network that is on our device. While the operator identifier is in charge of recognizing the operator used automatically. The Access Point Name structure consists of:

Network Identifier

The first Access Point Name structure is the network identifier which is the most mandatory part because it has a role that defines the external network to which the GGSN (Gateway GPRS Support Node) is connected.

Operators Identifier

This section is optional which is used to define a specific carrier packet network in which the GGSN resides.

Here there is an MCC (Mobile Country Code) or country code and MNC (Mobile Network Code) or cellular network code that can identify the service used automatically.

Access point name, of course, there is some special information including profile name, username, password, type of authentication, proxy, and so on.

This information is used as data or consideration by operators who are given internet access on mobile phones.

By using the Access point name, the operator can ensure that our device has got the correct and suitable IP address so that it can connect to the gateway safely. So that users can enjoy the internet safely and comfortably.
