Hi and welcome. The pencil is at the bottom and its not green, not sure if this was previously green or just looks different depending on theme and browser.
The Fairphone is a niche device and it will not show up as supported in many cases because of that. But that does not mean that it doesn’t work. This is one reason why we have the wiki.
I can’t edit the wiki page myself, but would like to note that in France, Orange (France) is offering eSIMs (and even sells the Fairphone).
I currently live in France and easily changed my old hardware “Orange” SIM with an eSIM online. Took about 2 minutes, the swap costs €10. My Fairphone accepted it without problem and is working fine since (5G and all).
Could somebody please add that?
