  • Development of Android’s dual-device “eSIM” sharing feature has been found to be progressing further.
  • An analysis of the app files from the Android “Google Play services” app v26.45 update confirmed that resource codes related to the setup, completion, cancellation, and error screens for the dual-device “eSIM” sharing feature have been added.
  • When sharing a single “eSIM” across two devices, the process appears to involve completing procedures on the carrier’s screen as well.

We previously reported on our original content site “App Teardown” that resource codes related to the setup screen for the new Android “eSIM” dual-device sharing feature were added in the Android “Google Play services” app version v26.44 update.

The Android dual-device “eSIM” sharing feature is attracting attention as an “Android Handoff”-style feature—similar to Apple’s “iPhone Handoff” feature introduced in iOS 27—that allows a single “eSIM” to be shared between two devices.

Now, in the subsequent Android “Google Play services” app version v26.45 update, it has been revealed that development on Android’s dual-device “eSIM” sharing feature has progressed even further. We bring you the details through our “Jetstream” original app file analysis report content, “App Teardown”.

An analysis of the app files from the Android “Google Play services” app v26.45 update, released around Friday, November 13, 2026, confirmed that resource codes for the setup, completion, cancellation, and error screens regarding the dual-device “eSIM” sharing feature have been added. Furthermore, the UI mockups for each screen based on these resource codes have also come to light.

At the time of the previous Android “Google Play services” app v26.44 update, what had been discovered was limited to “Set up %1$s SIM” displayed on the currently used Android device, along with instructions to scan a QR code displayed on the other Android device. This time, the flow has been revealed where “Setting up %1$s SIM…” is displayed during setup, followed by “Your SIM is ready to use on both phones” once the setup is complete.

<string name="esim_provisioning_application_label">eSIM setup</string>
<string name="esim_provisioning_sim_title">Setting up SIM…</string>
<string name="esim_provisioning_with_carrier_title">Setting up %1$s SIM…</string>
<string name="esim_provisioning_success_title">Your SIM is ready to use on both phones</string>

Additionally, if you attempt to exit the setup midway, a prompt asks “Exit without setting up SIM?”, accompanied by the message “Your SIM won’t be set up on your other device”. In case of a setup failure, it displays “Can’t set up SIM” and directs the user to contact their carrier.

<string name="esim_provisioning_cancel_dialog_title">Exit without setting up SIM?</string>
<string name="esim_provisioning_cancel_dialog_message">Your SIM won't be set up on your other device</string>
<string name="esim_provisioning_error_title">Can't set up SIM</string>
<string name="esim_provisioning_error_content">Something went wrong while trying to set up your SIM. To fix the problem, contact your carrier.</string>

In addition to processes named “multidevice” and “companion provisioning”, processes for displaying the carrier’s web screen mid-setup have also been added. This means that when sharing a single “eSIM” across two devices, the workflow is expected to include procedures on the carrier’s side.

The phrasing on the completion screen, “Your SIM is ready to use on both phones,” indicates that users will be able to use a SIM on two Android devices under a single “eSIM” subscription. This should make it easy to switch between your daily-use Android device and another Android device for work or going out, all while keeping a single “eSIM” contract.

By the way, details such as whether incoming calls can be received on both devices simultaneously, whether you switch and use one or the other, compatible carriers, and eligible Android devices remain unconfirmed. The actual rollout of Android’s dual-device “eSIM” sharing feature is also unconfirmed. At this stage, development is simply underway, and it remains a new feature that we hope will be officially released in the future.
