Messages
iMessage service
With the Messages app and the built-in iMessage feature, you can send text
messages over Wi-Fi to others using iOS 5 or later, or OS X Mountain Lion or
later. Messages can include photos, videos, and other info. You can see when
people are typing, and let them know when you’ve read their messages. If you’re
signed in to iMessage using the same Apple ID on other iOS devices or a Mac
(OS X Mavericks or later), you can start a conversation on one device and
continue it on another. For security, messages you send with iMessage are
encrypted before they’re sent.
With Continuity (iOS 8 or later), you can also send and receive SMS and MMS
messages on your iPad, relayed through your iPhone. Both your iPad and
iPhone must be signed in to iMessage using the same Apple ID. Charges may
apply to the text messaging service for your iPhone. See About Continuity
features (on page) .
