Pixel IMS is a rootless Android application that enables VoLTE functionality on Google Tensor-based Pixel devices without requiring rooting or bootloader modification.
The tool addresses the problem of VoLTE unavailability on Pixel phones in regions where carriers have not officially enabled the feature. It works by leveraging the internal Android API `telephony.ICarrierConfigLoader.overrideConfig()` to override carrier configuration settings. The approach requires ADB access through a computer connection and uses Shizuku, a service that grants access to system APIs normally restricted to privileged applications, to apply the necessary patches.
Adoption is limited to Pixel devices running Android 11 or later with Google Tensor chipsets, including Pixel 6 through Pixel 8 series and Pixel Fold. The tool is most useful for users in regions where their carrier does not officially support VoLTE on these devices. Primary support covers LG U+ in South Korea with confirmed working status; community testing has identified additional compatible carriers documented in the project's compatibility chart. Users should be aware that on Android 16 QPR2 Beta 3 and later versions, Google security patches may cause the applied patches to reset after device reboot, requiring reapplication.
The project maintains active troubleshooting documentation and a compatibility chart updated by community contributions. Development appears focused on supporting specific carrier configurations and addressing compatibility issues as they arise across different Android versions and device variants.
