I recently got a Pixel 6a and will attempt to install Graphene in the next few days,, wanting to have more privacy.
I have service US Cellular, and I just noticed this on the grapheneos.org/usage page:
"Android 12 introduced support for the GSMA TS.43 standard where provisioning for VoLTE, VoNR and 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, and Cellcom US are using this standard."
I know that Google Play can be installed sandboxed to install Play Store apps (but no idea how to at this point). Is there a particular folder or method to do this since this relates to the carrier and not a Play Store app?
I'm not very tech oriented and this process is intimidating. I definitely do not want to have to spend hours/days troubleshooting and hacking and be without a workable phone.
