The documentation below is about one Settings Package that may be installed on your SIM along with other Settings Packages. When combined, the how your SIM behaves may differ from what is described below.
The base-settings Settings Package contains the general settings that control how the SIM behaves. This includes but is not limited to which IMSIs will be chosen by Super SIM's multi-IMSI applet under different conditions and the different applets running on each SIM.
If a SIM has additional Settings Packages installed on it, portions of the settings controlled by base-settings may be overridden to deliver a customized experience.
We are currently maintaining 2 parallel branches of base-settings versions. Versions with a major version of 2 (i.e. 2.x.0) were manufactured with new versions of applets running on the SIM and an additional IMSI. SIMs ordered from Console will begin on major version 2. SIMs using base-settings packages with major version 2 may have access to different networks in different countries compared to the SIMs using base-settings packages with major version 1.
SIMs purchased before Summer 2021, prior to Super SIM reaching General Availability, may have major versions of 0 or 1 (i.e. 1.x.0). These older SIMs will eventually be over-the-air updated to have the same settings as newly manufactured SIMs at which point their major version will be updated to 2 (e.g. 2.x.0). Until that convergence happens, we will continue to introduce new versions of base-settings for major version 1 (e.g. 1.y.0).
Improves ability for Cat-M devices to take advantage of eDRX to conserve battery power.
Fixed an issue that may have hindered devices performing combined attachments from connecting to AT&T US. Modified which IMSI is preferred in some countries to improve the experience. Corrected the error introduced in version 2.1.0 for SIMs that already downloaded and installed the update.
Fixed an issue that may have hindered devices performing combined attachments from connecting to AT&T US. Modified which IMSI is preferred in some countries to improve the experience. Introduced an error whereby in some countries an incorrect IMSI will be used limiting the networks that the device can connect to before failing over to backup IMSIs. OTA updates to this version were canceled after the error was detected and updates to version 2.2.0 were released to fix impacted SIMs.
Fixed an issue that may have hindered devices performing combined attachments from connecting to AT&T US. This patch version was applied to devices that were already connecting in the United States in December 2021. A minor version update was introduced subsequently to update all SIMs using major version 2.
Added an additional IMSI expanding the number of networks available on Super SIM. Modified which IMSI is preferred in some countries to improve the experience.
Fixed an issue that may have hindered devices performing combined attachments from connecting to AT&T US. Modified which IMSI is preferred in some countries to improve the experience.
Modified which IMSI is preferred in some countries to improve the experience. For SIMs that received version 1.0.1, this version erroneously undid the fix for the issue that may have hindered devices performing combined attachments from connecting to AT&T US.

Replaced the multi-IMSI applet with a new version allowing SIMs to correctly failover to backup IMSIs on the SIM if the device is unable to connect to a cellular network after a few minutes. SIMs can be forced to switch IMSIs by issuing AT commands to the modem.
Replaced the applet responsible for managing over-the-air updates with a new version. You can prompt your SIM to check into the OTA update service and download any updates waiting for it by issuing AT commands to the modem.
Modified which IMSI is preferred in some countries to improve the experience.
Fixed an issue where the SIM would prefer an IMSI in the United States that did not have access to AT&T, limiting devices to T-Mobile unless they failed over to other IMSIs.
Added an additional IMSI to Super SIM improving coverage in Europe. Erroneously preferred an IMSI in the United States that did not have access to AT&T, limiting devices to T-Mobile unless they failed over to other IMSIs.
First iteration of Super SIM.
