Android/iOS Cross-Platform eSIM Transfer Adds Cloud Support: App Teardown

SIM Manager app-teardown
この記事のポイント
  • There is a possibility that “cross-platform eSIM transfer” via the cloud, which does not require scanning a QR code, will be rolled out in the future.
  • After analyzing the app files of the Android system app “SIM Manager” version D.2.1.944346941-google, we confirmed the addition of resource code related to “XosConnectionService,” a feature that enables cross-platform eSIM transfer via the cloud.
  • This is expected to be part of the preparations for the rollout of cloud-based cross-platform eSIM transfers.

In Japan, the “cross-platform eSIM transfer” feature, which allows transferring eSIM profiles between Android and iPhone, became available in mid-February 2026 through KDDI, Okinawa Cellular, and UQ mobile.

Currently, “cross-platform eSIM transfer” is provided through an orthodox method where the user scans a QR code displayed on the source device with the destination device. In practice, this QR code scanning method works by encoding the “Session ID” and “Pairing Code” required for the transfer into the QR code for automatic input.

However, it is possible that a cloud-based “cross-platform eSIM transfer” that does not require QR code scanning will be rolled out in the future. This possibility was revealed through our original content, “App Analysis.”

After analyzing the app files of the “SIM Manager” system app for eSIM-compatible Android devices (version D.2.1.944346941-google), released on Monday, July 20, 2026, we confirmed that resource code related to “XosConnectionService”—a feature to realize cross-platform eSIM transfer via the cloud—has been added.

<service android:name="com.google.android.euicc.xos.XosConnectionService" />
<string name="transfer_continue_on_iphone_title">Continue on your iPhone</string>
<string name="transfer_continue_on_ipad_title">Continue on your iPad</string>

<string name="xos_stop_sim_transfer_dialog_title">Transfer SIM later?</string>
<string name="xos_stop_sim_transfer_dialog_description">Your SIM hasn't transferred yet. To transfer your SIM after setup, go to Settings.</string>
<string name="transfer_continue_on_iphone_title">iPhone で続行</string>
<string name="transfer_continue_on_ipad_title">iPad で続行</string>
<string name="transfer_continue_on_cloud_device_title">%1$s で続行してください</string>
<string name="transfer_connecting_to_device_title">%1$s に接続しています…</string>
<string name="xos_stop_sim_transfer_dialog_title">SIM の移行を後にしますか？</string>
<string name="xos_stop_sim_transfer_dialog_description">SIM はまだ移行されていません。セットアップ後に SIM を移行するには、[設定] に移動してください。</string>

The addition of the “XosConnectionService” feature to the “SIM Manager” app is likely a preparation for the rollout of cloud-based “cross-platform eSIM transfers.” It will probably be enabled in the future, alongside corresponding support on the iOS side.
