airmedic Do I need to remove a physical SIM card from my Pixel 8a prior to installing GrapheneOS?
I am unaware of a need to do that.
airmedic I am concerned that the install procedure may somehow affect the card
The flashing process updates firmware if need be, installs an AVB key, and installs a bootable system image. It does not wipe eSIMs and does not overwrite the contents of a physical SIM (which would not be easy anyway).
