benjib1980 Still on Cellcom here and want to try again w/ my Pixel 8. You would think this is fixable..?
It's possible that the last year of incremental changes to AOSP has included a fix to whatever was going wrong, or that the last year of incremental changes to the GrapheneOS compatibility layer for Google Play has delivered a fix.
If it hasn't been fixed yet, in theory it should be fixable. But if zero GrapheneOS developers live in an area covered by a carrier using GSMA TS.43 (this seems plausible) then it might be fixable in theory but not in practice.
If it works for some AOSP variant, that would be encouraging. Perhaps it's possible to check those user forums for information (which might be easier than installing multiple operating systems on your phone).
Or does anyone have a link where I can ask a dev?
