What is com.sec.epdg? & What is ePDG Test App?
Written by prodigitalweb

In recent times, com.sec.epdg or otherwise called ePDG Test App, is getting the most attention from mobile phone users. In this article, you get to know each necessary detail regarding this topic, especially the process of fixing its issue. It is the short form of “Evolved Packet Data Gateway.” The 4G long-term evolution network uses a single framework to relay both voice resources and the data. Besides, you can use it between the evolved packet core and the non-3GPP network.

If you are an android user, you can then get it available as a non-deletable application. This one is a fixed part and parcel of the system application your device has. The app is working in the background of your device so that your phone can function correctly. Whether you find any issues, you can fix them only; you should not delete them.

What is com.sec.epdg?

com.sec.epdg is a non-deletable Android system application. It is Evolved Packet Data Gateway that uses a single frame network in 4 G communication. And, it is a single framework to relay both the voice and data packets. Besides, it helps your device to work seamlessly between the evolved packet core and the non-3GPP network. It works in the background for the smooth functioning of your device.

What is This App for?

 SAE is the core network architecture that is about the 3GPP’s LTE wireless communication standards. The app is part of the architecture.It interferes with non-trusted 3GPP IP systems. If you want to know about this, in short, it is a test to enable Wi-Fi calling. The 3GPP means the 3rd Generation Partnership Project. It is a standard organization term for the protocols that are invented for mobile telecommunications.

Can You Install the App?

 As it doesn’t cause any harm to your device, you don’t need to uninstall it. You have to be a user with different system encryption to uninstall it. However, you get benefits from this app, like device security.

Whether you want to eliminate it from your device, then you can block it first. To do so, you need to use the Titanium Backup, designed for this purpose.

What are the Permissions That the Epdg Test service App Has? 

Android services need a few basic permissions to function correctly on their devices, such as phone, storage, and other necessary permissions. However, to run this test app, you don’t need to grant any permission as this built-in app comes with all necessary permissions. Mobile phone manufacturers like Samsung are top-rated as they usually install the Epdg Test service App on the devices.

Is the App Safe to Use, or is It a Virus? 

A few people have a little bit of confusion regarding whether they should install it on their devices or not. Some users assume it is spyware or malware, but it is not the case. It is just a system app that has some specific function in each android mobile device.

The best way you can follow is to save all the essential files and then do Factory Reset your mobile. It is a straightforward method to follow. Besides, the method does not cause any effect on your system or other apps.

What do you mean by ePDG? 

Before going to the term com.sec.epdg, it is better to know a bit of ePDG. The 2G and 3G network architectures generally use circuit-switched (CS) & packet-switched (PS) for voice and data communication. Besides, the 4G Long-Term Evolution (LTE) network takes the help of Evolved Packet Core (EPC) for voice and data communication.

EPC is a single framework used in this case. The epdg is responsible especially for handling security and authentication with the help of protocols such as IPSec/IKEv2 or proxy mobile IPv6. It integrates multiple core network functions in a single node. It performs backhaul security through IPSec tunnels, tunnel set-up rates, and deep packet inspection.

What are the Features of the app? 

Here, we have given a few features of the app that are as follows:- 

  • It has an SWu & S2b interface that allows you to interwork with Wi-Fi attached to UE & PGW.
  • The app contains Hardware-based packet processing engines and features Multi-tier redundancy.
  • It is compatible with scalable ATCA and COTS Server-based standard platforms.
  • It comes with an SWm interface that can interwork with 3GPP standard AAA.
