Definition
An Access Point Name is a setting mobile devices use to access the web. It recognizes the network provider and type (4G, 3G, GPRS, GSM) and works as a ‘gateway’ between the internet and the cellular network.
The following processes use Access Point Name:
- Determining the required network
- Allocating an IP address to a device
- Configuring security standards
Access Point Name Modification
Usually, the APN information is completed automatically when you insert the SIM or eSIM card in your device, and you don’t have to do anything else to access the internet. However, if the device has connection problems associated with the APN, we recommend resetting the network settings.
Although the APN settings may be changed, the correct values vary based on the network and phone.
Difference Between a Public APN and a Private APN
APN is offered in two main categories: private and public. Each has its own set of benefits and drawbacks, as explained below:
Public APN
Most mobile network operators (MNOs) provide a public APN that includes basic settings for internet connectivity. It facilitates common tasks that customers perform on the network, and most users often share the same APN. This APN may include security features like firewalling access from external devices, which stops a device from communicating with another if it’s unidentifiable in the network.
The public APN offers a simple configuration that enables you to access the network. However, it does not allow you to customize settings and security features necessary for IoT deployment. If an APN is interpreted as a public APN with a static public IP, it assigns a device an IP address that becomes that device’s unique IP, which will be used each time it connects to the network.
Private APN
A private APN enables you to examine and customize network settings, enabling you to build a network tailored to your requirements. Previously, you needed significant resources to get a truly private APN.
Thankfully, achieving a similar level of network personalization today has become easier. For example, if your APN is backed by a software-defined network (SDN) you can essentially craft your own mobile network without the extra overhead of building physical infrastructure.
What is the Difference Between an APN and a VPN?
An Access Point Name (APN) is a gateway that lets you connect to the internet via your carrier network. On the other hand, a Virtual Private Network (VPN) is a sophisticated technology that establishes a secure connection to another network while accessing the internet.
