- In the future, when multiple SIMs are configured on a source Android device—such as through dual SIM, dual eSIM, or multiple eSIM profile support—it appears that Android will support a “multi_transfer” feature to batch-transfer them all at once to a destination Android device.
- An analysis of the app files from the Android system app “SIM Manager” version D.2.1.975645525-google update revealed the addition of resource code related to “multi_transfer,” which allows multiple SIMs and eSIMs to be transferred together.
- If the “multi_transfer” process takes time, it appears to run in the background, allowing users to perform other setup tasks concurrently.
Currently, when switching to a new Android device, if your carrier supports the “eSIM Quick Transfer” feature, you can transfer your eSIM right along with the data migration flow without needing to reissue the eSIM profile.
Additionally, if your carrier supports “eSIM Quick Transfer,” you can also convert a physical SIM inserted in the source Android device into an eSIM and transfer it to the destination Android device. Furthermore, so-called “cross-platform eSIM transfer” between Android and iOS has been available since September 2025.
However, these “eSIM Quick Transfer” features are designed to migrate only one SIM data at a time.

In our original app file analysis content “App Analysis” here at Jetstream, we bring you the details.

An analysis of the app files from the eSIM-compatible Android system app “SIM Manager” version D.2.1.975645525-google, released on Wednesday, September 23, 2026, confirmed the addition of resource code regarding “multi_transfer,” which enables the batch transfer of multiple SIMs and eSIMs. This “multi_transfer” feature not only allows multiple eSIMs configured on the source Android device to be transferred all at once, but it also appears to allow multiple physical SIMs inserted in the source Android device to be converted into eSIMs and transferred collectively.
Of course, physical SIMs converted to eSIMs will no longer be usable, and resource code regarding warnings about this has also been identified. Additionally, resource code outlining precautions when performing a “multi_transfer” to devices that do not support dual eSIMs can be found.
Furthermore, if a “multi_transfer” takes time, it seems that the transfer will operate in the background, allowing users to proceed with other setup procedures.
