Get a phone number like everybody. You are like 0.0000001% of the market. Nobody is going to twist their product to cater to you.
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.
And of course that statistic is made up. It was a joke.
Are you in a country which doesn't have pay-and-go service?
