What are APNs? How Does It Work and Function? ~ PT. Network Data System

For a smartphone user, especially Android, of course we are already familiar with what is APN.

Maybe some of us are still confused about APNs, so this article is here to help you understand APNs, APN functions, APN types, and also APN configuration. Let’s take a look at the following APN reviews:

What are APNs?

Before we discuss further about what an APN is, we need to know its definition first.

APN is

What is APN?, APN is a gateway or gateway between internet connections such as GPRS, GSM to 3G and 4G networks.

So that the user’s mobile device must set this Access point name so that it can use the operator’s signal.

Use is also used as a protocol for IP addresses must be identified by network devices.

Use of APN

APN function in general is to connect multiple devices with network provider operators.

So this APN is used to access the internet for android users according to the type of operator used.

Perform Device Registration

The first APN function is that a smartphone or computer to a computer network will be registered by the APN.

In addition, we will also get internet access, the type of service we use and the time period.

Obtaining a Public IP Address

This APN is used to provide an IP address to our device which is connected to a mobile operator.

This APN serves to get IP addresses for our devices so that they can be recognized and can connect to the internet.

Speed ​​Up Internet Connection

There are some people who say that this APN can also be useful to facilitate a fast and stable internet connection.

APN can be used only to reduce the number of connection pings so that the surfing experience is more comfortable.

APN Implementation

Using or configuring the APN is actually not that difficult which means you don’t need to download any additional apps.

The APN configuration can be done by going through the device settings on your cellphone. Here are some ways to set the APN on some mobile devices:

On Android devices

  • You can open settings on android.
  • Select Network > Mobile Network > click Access Point Names.
  • Click Add APN, if it doesn’t exist then you can click the three dots located at the top.
  • Then fill in the APN settings according to your operator then click Save.

On iOS devices

  • Open settings.
  • Select Cellular > Cellular Data Options > click Cellular Data Network.
  • In your APN settings fill in according to your carrier.
  • When finished then click Save.

How to Add or Change Your APN

This APN will usually be automatically configured by itself. So you don’t need to set it manually or change it. Because of that, it is feared that the existing settings may even result in a connection error or error.

There may be several reasons why you should modify the APN on your phone. The first is that there is an incorrect message after such as “Unable to activate the data network …”.

Both are free to use any operator. The third is usually consuming mobile data. Fourth is to go outside the service area who wants to avoid expensive roaming rates.


If you have one, follow the steps to change the APN below:

  • Enter the Settings menu.
  • Select Mobile Networks.
  • Then, select Access Point Name.
  • Click New APN and change the settings according to the operator used.


For how to set the APN on your OPPO cellphone, you can follow these steps:

  • Then you select the Access point name or APN.
  • Select the exclamation mark that is parallel to the operator name then select the + sign to change the new APN.
  • After that, fill in the APN according to the cellular operator you are using.
  • Select Save after changing the APN settings.

In the article about APNs, of course we know the two networks that we usually find on cellular networks, namely 3G and 4G networks.

Which is not much different from the APN settings for 4G which is because it is the name used for the APN and both use the same APN. The difference is in the selection of the network mode used.

For how to set APN 3G/4G LTE as mentioned earlier, this is one of the best options for implementing APNs on your cellphone, and can also be applied to a Tablet or PC.

How APNs 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.

APN itself has some important information that is used as consideration for internet service provider operators, namely in the form of username authentication, passwords, authentication, profiles and others.

APN Types

There are two most common types of APNs, including public APNs and private APNs and are further differentiated by using IP addresses, namely static IPs and dynamic IPs:


A public APN is a type of APN that is provided by operators for network connections in general. Usually what type of public is most often used by most people.


This type of public APN with a static IP is almost the same as a public APN but has a static IP.


With private APNs, devices can connect devices to the internal APN network using a gateway or VPN.


Gateway or VPN assigns a static IP to the device.

APN Structure

APN also does not stand alone because it has two structures, namely network identifier and 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 APN structure consists of:

Network Identifier

The first APN 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.

Operator 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.

Of course, the APN contains some special information including profile names, usernames, passwords, authentication types, proxies, and so on.

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

By using the APN, 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.


That’s the article this time that discusses in detail about APNs, APN functions, how APNs work, types of APNs, to how to configure APNs according to the most common operators in Indonesia.

Talking about APN is certainly related to providing internet for individual or organizational needs, so you should trust the internet network provider service at NetData.
