GrapheneOS aims to work with all carriers that are officially supported by Google - on the stock operating system on Pixel devices. Wi-Fi Calling, VoLTE, Visual Voicemail, - MMS, SMS, Calling and 5G (SA and NSA) all are supported, however some functionality may - not be usable due to Google not supporting carriers on the stock OS officially or - due to GrapheneOS not shipping proprietary apps required in order for this - functionality to work on some carriers. GrapheneOS extracts CarrierConfigs, APNs, - modem configurations, Visual Voicemail configurations and MMS configurations from the - stock operating system to ensure users get easy carrier support that "just works".

-If you are having issues with Visual Voicemail, please be aware that AT&T USA - users are unable to use this feature currently due to a lack of AOSP support.

Some carriers may restrict functionality, such as VoLTE, on imported Pixel devices as they only - whitelist the IMEI ranges of Pixel device SKUs which were sold locally. You can check your - SKU on GrapheneOS by going to Settings ➔ About phone ➔ Model ➔ Hardware SKU and using the - official Google documentation. You should check if such functionality works on the stock OS to troubleshoot. - It is not possible to change the IMEI on a production device and GrapheneOS will never add - support for this.
- -Android 12 introduced support for the GSMA TS.43 standard, where provisioning for VoLTE, - VoNR, Wi-Fi calling may be handled by Google Firebase. Currently it is very rare for - carriers to be using Firebase to handle this. It is unlikely, but technically possible, that - with such carriers, you may be required to install sandboxed Google Play in order to obtain the - former mentioned functionality where the carrier has not implemented fallback provisioning via SMS. - Currently only US Cellular, Orange France, Cspire US, Cellcom US are using this standard.
