(1) it feels more homely and adult which makes me happy (2) it allows me to give out a valid phone number to low-trust strangers like companies, clients, to put up in imprints and privacy policies etc. that isn't my mobile phone that people could immediately find personal info with, e. g. my bios and profile pictures on messengers or my bank account and so on (3) i don't get bothered by stressful calls like work or doctors or compabies and stuff when i'm out and about because they don't go to my phone
