Show HN: Chat with your contacts on different platforms without an app

How can you provision and use a phone number for each contact? What if I have hundreds or thousands of contacts? Doesn't this use up all available phone numbers?

What about when I stop using the service - are these numbers able to be re-used?

What about security or privacy implications of the next person messaging my old contacts accidentally?

I think each of their phone numbers are reusable by also keying against who the sender is. So if they own the number 555-1234, Alice can sign up and have texts to that number go to Bob, and Carol can sign up and have texts to that number go to Eve. This way, everyone who uses the service can each have as many contacts as the service has phone numbers, and it will work without issue.

What if Alice wants to send messages to Carol?

The number Alice uses to message Carol doesn’t have to be the same as the number Carol uses to message Alice.

From their landing page: > Simply create an account and connect your social media accounts.

You already have to have an account setup on the target platform, they won't provision one for you.
