I’ve found some cheaper pixels on e-bay, bought mine there.

You could be right. I looked at several of them on eBay and could only find phones with the e-sim, couldn’t find any with sim card tray.

Grapheneos has a wonderful how to install procedure. I did it with a Linux Debian machine. It took several tries to get the bootloader right, part of that was I didn’t know what I was looking for. Once your phone has the red triangle in the bootloader of the phone, the installer should recognize it, and the installer was awesome from there.

10 does not have a sim card tray, the 9’s do. First post with grapheneos on a new to me 9 I was able to get!
