eSIM (Embedded SIM)

eSIM (Also known as Embedded SIM) is our new technology which can
                provide not only various services based on 5G network but also available
                these on remotely. Our strong efforts for fulfilling 5G life will be a key
                to open brand new eSIM world to users. information

What is eSIM?

eSIM (embedded Subscription Identification Module) is a kind of SIM
which is soldered directly into the circuitry of Consumer and IoT Devices.
Compare to legacy SIM card, this one is more dedicated to
machine to machine (M2M) applications where there is no requirement
to change the SIM card, this avoids the requirement for a connector,
improving reliability and security.

Point of Different

  • Built-in type into the IoT Devices which is smaller size than previous USIM.
    (no need to purchase new SIM when changing the MNO)
  • It can have more than one MNOs’ SIM function and remote opening, termination, and
    operator change can be made according to the user's request.
  • Strengthened security compare to previous USIM.

Scope of Application

IoT(Internet of
Things) Devices

To interconnect information of numerous IoT devices through eSIM

Connected Car

Autonomous vehicle network connection allows access to real-time
information such as traffic conditions, nearby amenities, navigation,
vehicle diagnostics, and emergency services regardless of location and time

Smart Factory

Enhances factory automation and industrial security across production,
logistics and manufacturing management systems
