What it is

Messaging that needs no app, ever.

SMS is the only channel built into every mobile phone on the planet. No download, no login, no data connection — if it has a SIM, it gets your message. That universality makes SMS the most dependable way to deliver one-time passwords, time-critical alerts and offers that simply have to be read.
