Are you paying for it?

I can be reached by telephone. What I don't have is a unique telephone number. This works perfectly fine for actual voice communication. If you think I can simply afford an extra monthly expense, you're wrong.

Made up statistics reveal your presuppositions.

There are a lot of people that don't have a unique phone number. It's a minority position, but that's kind of my point: chat services do not inherently depend on traditional phone numbers, and requiring one is going to exclude more people than you probably realize.
