I live on a small island with poor cellular connection, so a phone number is pointless anyways. People explored the entire planet without phones, I can get by without WiFi for a few hours. When I visit more civilized societies where people have the expectation of immediacy in communication I just plan my days when I wake up. My friends and family all know that when you make plans with me it is usually more detailed than "I'm not sure where we will be, I'll text you later." I use apps for all of my day to day communication. Email is also one of my main communication channels. Some apps like PayPal are basically unusable without a phone number, so I don't use them. I get asked why I don't just buy a sim card when I visit other countries, and it really just boils down to liking being disconnected and bored of seeing people staring at their phones every time they are confronted with a problem.
