During work: I think it depends on your profession. If your job does not involve interacting other humans in any way, or you are all in the same room, then you do not need a phone to communicate. Job hunting: This would be significantly harder without a personal phone, but regular trips to a recruitment agent's office could make it possible. I can certainly see that it would be a significant advantage to have a phone. At home: Hugely depends on how far and wide your family have spread. If they are all within walking distance, then you don't need a phone. Sure it's more convenient, and sure, you'll spend a lot of time outside people's houses wondering if they're actually in, but that's how I grew up without a mobile phone. Interestingly, I would counter-argue (with myself) that you do need a phone if you are the only family member in a remote area, if only for your mental health. Emergencies: Yes, sometimes you just need a phone. So yes. A bit need.
