Installed GrapheneOS using GoogleFi went swimmingly for 3 months. Suddenly one day no cell service. Google tech support spent two weeks trying to resolve to no avail. I uninstalled and reinstalled their app many times, restarted, etc etc. Initially I couldn't delete their eSim, after several cycles of restarts I was able to again but never could fully reactivate their service. I got frustrated so I did a factory reset and went with another carrier. New carrier's app gets to the stage of downloading a new eSim and doesn't complete. The download progress bar just cycles forever. Their initial tech support couldn't resolve and now awaiting engineers to review.
Any thoughts on how to approach what appears to be an eSim issue? There is currently no eSim in the device and eSim support is on.
