Going Data only. No phone number.

Lots of people have cut their landline phone. Living purely on their mobile number. But can you take the next step?

Cutting your mobile plan down to data only. So no plain phonecalls, no SMS. Living purely on Skype, email, Facetime or the assorted other messaging apps.

How does a stranger contact you quickly? Is a phone number almost essential for employment and so forth? Is giving up voice telecommunications too antisocial (or delightfully antisocial. I can see the upside of cutting the voice)

Has anyone done it?
