What is com.sec.epdg? Keeps Stopping? – How to Fix Guide 2022

What is com.sec.epdg? It is a system file that comes pre-built into your device which means you cannot uninstall or remove it from your device. As it is a system file so it is involved in the background operation of your smartphone.

Epdg stands for Evolved packet data gateway. It is a single framework that is used by the 4g long-term evolution (LTE) network to relay both the data and voice resources.

LTE or long-term evolution. In Telecommunications, Long-Term Evolution is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases the capacity and speed using a different radio interface together with core network improvements.

Features of ePDG

  • 3GPP Standard ePDG Solution
  •  SWu interface to interwork with WiFi attached UE
  •  SWm interface to interwork with 3GPP standard AAA 
  •  S2b interface to interwork with PGW
  •  Hardware-based packet processing engines
  • Scalable COTS Server-based / ATCA standard platforms
  • Multi-tier redundancy ensuring carrier-grade 99.999% availability

Mobile Traffic Explosion

With the rapid explosion of data traffic, driven by Smartphones and tablets, operators are scrambling to deploy solutions to meet the growing demand. While the deployment of Long Term Evolution (LTE) networks has removed some of the pressure, that alone will not be enough to meet the upcoming stream made up of high-definition video streams (HD) and voice-over LTE (VoLTE).

And while there is no single “silver bullet” solution that will solve everything, there are many options for operators to choose from, such as small cells, WLAN integration, etc. The real question is “How can an operator deliver these services economically and without much impact on the existing network?”

Introducing the SMEC Evolve Packet Data Gateway

SMEC Evolve Packet Data Gateway (PDG) enables operators to integrate their 4G Long Term Evolution (LTE) with unreliable access networks that require security, such as WiFi.

Safety and Travel Agreement Support

ISMEC Evolve Packet Gateway (ePGG) is establishing IPsec secure channels between UE and ePDG via WiFi access network while using IKE to authenticate subscribers via a DIAMETER / RADIUS AAA connected via Diameter or RADIUS. Using a GTP or PMIP connection to P-GW, ePDG provides navigation support as the subscriber roams between WiFi and LTE networks, across all WiFi (MOBIKE) networks.

Working with Hardware

Available in a variety of Advanced TCA (ATCA) chassis standards and the COTS server platform, SMEC Evolve Packet Gateway (PDG) is the ultimate solution that can connect over 100 Gbps IPsec throughput and over one million IPsec channels.

A NEBS3 compliant solution, SMEC Evolve Packet Gateway (PDG) provides a completely redesigned structure that ensures no single point of failure and ensures maximum availability of five nines (99.999%).


By allowing operators to seamlessly integrate their WiFi access networks with their 4G networks, SMEC Evolve Packet Data Gateway (PDG) enables operators to increase their available bandwidth without adding additional channels and improve their service quality without additional costs. In addition, with its high performance and compact form factor, ePDG provides comparable performance to larger market-based solutions, which means that more initial investment is invested (CAPEX). And its good design reduces operating costs (OPEX). [ref]

Is com.sec.epdg malicious software?

Techemirate - com.sec.epdg has stopped

People often assume com.sec.epdg as malicious software or as a virus because of its bit tangled name. However, there is absolutely nothing to be worried about as it is a pre-built file system that is very necessary for your smartphone.

How to fix com.sec.epdg error?

what is com.sec.epdg

You might have encountered com.sec.epdg has stopped, error. That error is usually, occurs because you might have closed the app quite unexpectedly or forcefully. A third-party battery saver app can also contribute to this error.

To fix this issue, try rebooting your device. In most cases, this method fixes the problem.

If this method does not work then try to clear the cache of com.sec.epdg app

Here’s you can do so

Step 1– Go to settings

Step 2– Either look for app manager or app and notification, open it

Step 3– You will find three dots on the highest right corner, click thereon and                                                                        

Choose “show system apps” out of the many options you will be shown.

Step 4– Now, search for com.sec.epdg app

Step 5– Once found the app, open storage, and cache.

Step 6– Now clear the catch and afterward reboot your phone, this will settle things for good.

And somehow if still, this method doesn’t go well for you, then the only way of fixing this error is by doing a factory reset.

Note: Before proceeding with a factory reset, backup your device

There are numerous ways of doing so. You can backup data using the cloud or on a computer, wherever you feel ok doing so.

Backing up your data on the cloud can be a bit time-consuming as you’ll be needing a strong cellular data connection or a WIFI. Doing the same on a computer can be easier and time-saving.

Here’s how to do a factory reset

  • Tap Settings
  •  Tap General Management.
  •  Tap Reset.
  • Tap Factory data reset.
  • Tap RESET.

Wrapping up

In this article we explained what is com.sec.epdg and its features and how to fix the “com.sec.epdg has stopped” error.

However, doing a factory reset of your device, always consider this as the last option because a factory reset permanently deletes all your data for good. Sometimes backing up your device can be quite a drag and a time-consuming process. We will strongly recommend, trying to stick to the first two explained methods (rebooting your device and clearing cache) to tackle this issue.
