eUICC SIM: Change SIM profiles remotely

  • Add, manage or change SIM profiles remotely.
  • Available M2M standards: SGP.02, SGP.22, later SGP.32.
  • eUICC-SIM in the formats: 2FF, 3FF, 4FF & MFF2 (embedded SIM).

What is an eUICC SIM card?

eUICC SIM cards run software that allows the SIM to be replaced remotely by overwriting the profile stored on the SIM. This software can run on the typical plastic plug-in SIM cards as well as on soldered MFF2 SIM cards (embedded SIM). However, it is not possible to upload the software to a SIM at a later date.

There are currently three eUICC standards (SGP.02, SGP.22 and SGP.32) for which the profile change works differently in each case. IoT hardware must always support the respective standard in order to use it.

Advantages of eUICC SIM cards

An eUICC SIM has an overwritable SIM profile. This allows the network operator profile to be changed without physically replacing the M2M SIM.

Change profile remotely

Change profile remotely

SIM profiles can be managed and changed remotely via an online portal.

Extended storage capacity

Extended storage capacity

Larger storage capacity compared to UICC SIMs offers more options.

No physical SIM exchange

No physical SIM exchange

No need to replace the SIM card for profile changes/additions.

Freedom to Leave

Freedom to Leave

Interchangeable profiles reduce dependence on one network operator.

eUICC compatibility

eUICC is primarily a software functionality, not hardware. This means that SIM profiles can be overwritten or added to.

We offer our M2M and IoT SIM cards both with and without eUICC. We have IoT SIM cards with eUICC functionality (eUICC-ready) for all common SIM form factors, from 2FF, 3FF, 4FF to MFF2 (embedded SIM).

eUICC Ready

The three eUICC standards at a glance

eUICC is not the same as eUICC: Each standard is suitable for different applications and is not compatible with other standards.

loT Standard
GSMA SGP.32

  • Latest eUICC standard, developed for IoT and M2M devices
  • Optimized for low power consumption and therefore suitable for NB-IoT and LTE-M (LPWAN optimized), among others
  • Significantly reduced costs to use multiple mobile network providers
  • First certified hardware & SIM cards expected by the end of 2024
  • Mass suitability in 2025 at the earliest

Consumer Standard GSMA SGP.22

  • Standard for consumer devices such as smartphones, wearables and tablets
  • No pre-installed network operator profile available: Interaction with end device necessary to load profile
  • End device needs WLAN or similar to upload profile
  • Profile change is started by scanning the QR code or via app
  • Only suitable for end devices with display, camera or QR code scanner

m2m (automotive) Standard
GSMA SGP.02

  • developed as the first eUICC standard for M2M devices
  • Integration of a second network provider is very expensive and time-consuming
  • Profile change is initiated remotely, no user interaction required on the end device
  • Used almost exclusively in very large projects, e.g. in the automotive industry
  • High power consumption and therefore unsuitable for LPWAN end devices

eSIM, embedded SIM and eUICC

The abbreviation eSIM is usually used for both embedded SIM and eUICC, although the two mean different things. eUICC describes the software on a SIM card. An embedded SIM refers to a specific hardware form of a (M2M) SIM card, a SIM chip permanently installed in the end device.

There are embedded SIM cards with eUICC functionality. An embedded SIM with eUICC makes sense, as these SIM cards are permanently installed or soldered into end devices, meaning that a physical SIM replacement is only possible with a great deal of (cost) effort.
