After a lot of problems with my old Galaxy S4 randomly saying “SIM card not detected” and rebooting, I tried to fix the SIM card reader. I ended up breaking it even more. I just replaced it for a new one (~US$5). I wouldn’t go as far as calling it a modular smartphone but it’s nice to own something and be able to fix it yourself.
