I went the feature phone route, bog standard Nokia with a 64 GB SD card in it for music/etc. I managed three months and then a customer sent me an iPhone because sending SMS's was too much of a hassle when everyone else was on Slack 24/7, and because their authentication scheme was changing and they required a smart phone app for 2FA. Years later, I still refuse to put Slack on my phone (now an Android), but I can't get away from various app requirements connected to my business number, and I can't be bothered to have two separate phones when I have two SIM slots in my phone anyway.
