Off topic, but I went without a phone for about 9 months (technically, I had a phone, it just wasn't connected, so it really just acted as a portable wifi device) and it really was quite liberating and freeing knowing that once I left home/the office, I was not contactable. I didn't use other people's phones, I just used the internet (on my home wifi or office wifi) to communicate with people. It did mean I had to plan things ahead of time instead of the usual quick call "hey, I'm at X, where are you" type thing, but hey, we did that before mobile phones too, without problem. The only thing I really did miss was google/apple maps.

Eventually a family member got annoyed though and bought me a new sim. :/
