Hi Cedric,
thank you for sharing your first impressions. I'm glad you like it! :-)
Your walk up the hill just to test telephony is really cool. After so much battling with the modem, I'm positively surprised that the interaction with the SIM card and phone calls seem to work quite nicely overall.
BTW, there is a bit of discussion about Genode on the PinePhone on the Pine64 forum now [1].

Once we have the Wifi driver added, you will hopefully be able to get more entertainment out of the various presets. Please stay tuned.
Cheers Norman
