Yes, becoming a minimalist has essentially taken over my life, so-to-speak. I’m constantly looking for new ways I can simplify and I’m constantly reevaluating where I am with my lifestyle.
The reason for two phones was just as you guessed: my primary phone is the smartphone, which I use for so many things (contacts, calendar, email, web, passwords, research, GPS, camera, phone, etc.). However, in some countries it can be difficult to find a SIM card for the iPhone, so I also keep a cheap Nokia phone that uses a regular SIM card. I purchased the Nokia phone when I was in India because I couldn’t get my iPhone working as a telephone there and I wanted a way of texting/calling if I needed to. That phone cost me about $5 USD and I still have it today. 🙂
