New Super SIM hardware and applets updates - April 2025

You are receiving this message because you are a Super SIM customer.

Important: Some of the upcoming changes may impact your device behavior or connectivity. Carefully review the following information or inform a technical person on your team about these changes to KORE Super SIM.

Changes to Super SIM hardware beginning Q3 2025

As we complete our separation from Twilio, we will be making updates to our SIM hardware, eSIM profiles, and the applets that power Super SIM – beginning in Q3 2025. Most changes below will only be on a go-forward basis for newly manufactured SIMs. The changes to our applets can also be made over-the-air and should be eventually applied to all active SIMs. Refer to the migration guide for additional details. Our changes are summarized below.

• ICCID prefix change The ICCID prefix on newly manufactured Super SIMs will change from 8988307 to 8910392. If you use this identifier to manage logic in your device’s firmware or in other applications, you will need to update them. If you use other KORE SIMs in addition to Super SIM, you may need to also make changes to distinguish Super SIM from other KORE SIMs. Some other KORE SIM products use the 890139 ICCID prefix (note that this is before the “2” in the Super SIM prefix above). Ensure that you can properly distinguish Super SIMs from these other KORE SIMs so that you do not encounter issues configuring your devices or updating your SIMs. Refer to our Super SIM ICCID article for detailed information.

• Service Provider Name (SPN) change The service provider name (SPN), a readable value on the SIM, on newly manufactured Super SIMs will change from “Twilio” to “KORE Super SIM.” If you use this to manage logic in your device’s firmware or in other applications, you will need to update them to account for the new value. We will not be updating the SPN on existing SIMs. SIMs with the 8988307 ICCID prefix will continue to use the “Twilio” SPN and SIMs with the 8910392 ICCID prefix will use the “KORE Super SIM” SPN. Refer to our SIM's APN article for more information.

• SIM applet and local command updates We are updating the multi-IMSI, and over-the-air (OTA) polling applets installed in Super SIMs. If you use the current AT+CSIM commands that allow your device to trigger applet functionality locally, you will need to make changes to your device’s firmware as these commands will change with the updated applets. The updated applets will first be installed in newly manufactured Super SIMs, but will also be deployed over-the-air to your existing SIMs. Documentation on how to use local AT commands to trigger actions in the multi-IMSI applet and OTA applet have been updated to explain the commands available with both the current and new applets.

• Switch to eSIM (eUICC) hardware To reduce the number of hardware variants we maintain and to improve the quality of the SIM hardware you receive, we intend to produce all new Super SIMs, starting with those produced with the new ICCID range indicated above, as industrialized eUICC SIMs (eSIMs). This will apply to plastic SIM cards, MFF2 embedded SIM hardware, and all other form factors. If you believe that this hardware change will introduce problems when designing, manufacturing, or deploying your devices (current or future), we want to hear from you. Please create a support case or email Support to share your concerns.

For more details about these changes, how to identify if they apply to you, and what you may need to do, refer to our migration guide.

We plan to begin shipping new Super SIMs with these changes beginning in Q3 2025, and over-the-air updates to SIM applets are expected to begin before the end of the year. We will provide more details on our timeline in a future update.

You can find copies of all Twilio IoT acquisition advisories on the KORE Documentation Hub.
