A fully free and open-source Local Profile Assistant implementation for Android devices.
There are two variants of this project, OpenEUICC and EasyEUICC:
| OpenEUICC | EasyEUICC | |
|---|---|---|
| Privileged | Must be installed as system app | No |
| Internal eSIM | Supported | Unsupported |
| External (Removable) eSIM | Supported | S AD75 upported |
| USB Readers | Supported | Supported |
| Requires allowlisting by eSIM | No | Yes -- except USB |
| System Integration | Partial (carrier partner API unimplemented yet) | No |
Some side notes:
- When privileged, OpenEUICC supports any eUICC chip that implements the SGP.22 standard, internal or external. However, there is no guarantee that external (removable) eSIMs actually follow the standard. Please DO NOT submit bug reports for non-functioning removable eSIMs. They are NOT officially supported unless they also support / are supported by EasyEUICC, the unprivileged variant.
- Both variants support accessing eUICC chips through USB CCID readers, regardless of whether the chip contains the correct ARA-M hash to allow for unprivileged access. However, only
T=0readers that use the standard USB CCID protocol are supported. - Prebuilt release-mode EasyEUICC apks can be downloaded here. For OpenEUICC, no official release is currently provided and only debug mode APKs can be found in the CI page.
- For removable eSIM chip vendors: to have your chip supported by official builds of EasyEUICC when inserted, include the ARA-M hash

This project is Free Software licensed under GNU GPL v3, WITHOUT the "or later" clause. Any modification and derivative work MUST be released under the SAME license, which means, at the very least, that the source code MUST be available upon request.
If you are releasing a modification of this app, you are kindly asked to make changes to at least the app name and package name.
Make sure you have all submodules cloned and updated by running
git submodule update --initA file keystore.properties is required in the root directory. Template:
storePassword=my-store-password
keyPassword=my-password
keyAlias=my-key
unprivKeyPassword=my-unpriv-password
unprivKeyAlias=my-unpriv-key
storeFile=/path/to/android/keystoreNote that you must have a Java-compatible keystore generated first.
To build the privileged OpenEUICC:
./gradlew :app:assembleReleaseFor EasyEUICC:
./gradlew :app-unpriv:assembleReleaseThere are two ways to include OpenEUICC in your AOSP-based system image:
- Include this project and its dependencies inside the AOSP tree.
- If inclusion in
manifest.xmlis required, remember to set thesync-soption to clone submodules. - The module name is
OpenEUICC. You can include it inPRODUCT_PACKAGES, or simply build it standalone usingmm. - Compilation of this project is only tested against the latest AOSP release version. The app itself should be compatible with older AOSP versions, but the source may not compile against an older AOSP source tree.
- If inclusion in
- If compilation against AOSP source tree is not possible, consider building with gradle and import the apk as a prebuilt.
- No official
Android.bpis provided for this case but it should be straightforward to write. - You might want to include
privapp_whitelist_im.angry.openeuicc.xmlas well.
- No official
-
Q: Do you provide prebuilt binaries for OpenEUICC?
-
A: Debug-mode APKs are available continuously as an artifact of the Actions CI used by this project. However, these debug-mode APKs are not intended for inclusion inside system images, nor are they supported by the developer in any sense. If you are a custom ROM developer, either include the entire OpenEUICC repository in your AOSP source tree, or generate an APK using
gradleand import that as a prebuilt system app. Note that you might wantprivapp_whitelist_im.angry.openeuicc.xmlas well. -
Q: AOSP's Settings app seems to be confused by OpenEUICC (for example, disabling / enabling profiles from the Networks page do not work properly)
-
A: When your device has internal eSIM chip(s) and you have inserted a removable eSIM chip, the Settings app can misbehave since it was never designed for this scenario. Please prefer using OpenEUICC's own management interface whenever possible. In the future, there might be an option to exclude removable SIMs from being reported to the Android system.
-
Q: Can EasyEUICC manage my phone's internal eSIM?
-
A: No. For EasyEUICC to work, the eSIM chip MUST proactively grant access via its ARA-M field.
-
Q: Removable eSIMs? Are they a joke?
-
A: No, even though the name "removable embedded SIM" can sound like an oxymoron. In fact, there can be many advantages to these chips compared to fully embedded ones. For example, the ability to transfer eSIM profiles without carrier support or approval, or the ability to use eSIM on devices that do not and may never get the support, such as Wi-Fi hotspots.
