iMessage lets you send and receive SMS-like text messages, and MMS-style multimedia messages just like a phone. Instead of a just a phone number, however, it uses your email address, and it only works with other Apple devices, like other iPads, iPhones, iPod touches, and Macs. Before you can start using messages, and sending texts, photos, videos, voice memos, locations, and contact cards, however, you need to set it up.
If you set up your device using iCloud there's a change iMessage is already set up as well, and good to go. If not, we'll show you how to get started, and get messaging, quickly.
