> JMP is $4.99 USD / month or $6.59 CAD / month, billed out of the balance on your account, for unlimited incoming and outgoing text and picture messages, and calling credit equivalent to 120 minutes of voice to the USA or Canada per calendar month [1]

Is this for real? What is the catch?

Sounds like Google Voice vs Google Fi distinction. JMP would be Google Voice and JMP Data Plan would be Google Fi.

You need a separate data plan (which they do offer). It's just a fancy XMPP-based VoIP service.

Adding to this, their home page says:

> Because we use the Jabber network […]

Wait, what does Jabber have to do with sending texts and making calls on mobile networks?

[NewJazz → codethief]

They run a gateway. They have a Jabber server, you send messages to it or make calls through it, they forward the texts and calls to their upstream provider.

Nothing. The phone number service does not use mobile networks, it uses the Internet via XMPP/Jabber. Connections to the Internet is your problem. Or buy the JMP Data Plan, which is a separate product all together.

That's the protocol used to communicate between your device and the gateway to the phone network. Taking the place of eg SIP as a more mobile friendly solution.
