When I tried that, it lasted me for almost a year and a half, before I unfortunately got a second job that required MFA and I needed to be more online in general due to juggling two jobs. And it was amazing!
What I eventually did however was to get a dumb phone that can do a wifi hotspot, and still carried my smartphone but without simcard and net access, and powered off. When I really needed to get a taxi or look up a way home when I overslept drunk on public transport and ended up who knows where, I could always just fire up hotspot, power on the smartphone and do stuff I needed. Cause when that happened first time, it was when I first realized how much dependent I am on smartphone and net access.
Thanks for reminding me, I just quit one of the jobs and I can afford to be more offline, so back to the dumb phone I go! Convincing my GF again that she has to text me instead of using discord will be hard, though ... Or explaining that I really cant look up the fact she wants, or call a taxi quickly...
I still have a python bot that forwarded discord messages to my own bare html website, so I can chat with her with the basic web browser of the dumb phone.
I'd go for scandiavia, if I could choose anywhere. Or Island, working for CCP is my dream job.
