(not op). I use a dumb feature phones that can receive SMS for far less than 40€ (even cheaper, but I like the music player and some other things like bluetooh for headphones). I have a "twin SIM", i.e. my mobile carier gives me a SIM with the same phone number and if somebody calls me, both phones (smartphone and feature phone) ring. SMS can only be received at one number, but you can switch the SIM for SMS reception using the carrier website. Since I only take the feature phone when I leave home (to enjoy outside time without distractions) I usually don't turn it on.
