Chapter 5 Internet services 49
iMessage
iMessage is a messaging service for both iOS devices and Mac computers that enables one-
to-one or group chats. iMessage supports text and attachments such as photos, contacts, and
locations. Messages appear on all of a user’s registered iOS devices and Mac computers, so the
user can continue a conversation on any one of them. iMessage uses the Apple Push Notication
Service (APNs) and end-to-end encryption with keys known only to the sending and receiving
iOS devices and Mac computers. Apple can’t decrypt messages, and messages aren’t logged.
Note: Normal carrier data rates may apply. Messages may be sent as SMS when iMessage is
unavailable; carrier messaging fees apply.
FaceTime
FaceTime is Apple’s video and audio calling service. FaceTime calls use the Apple Push
Notication Service to establish a connection, then use Internet Connectivity Establishment
(ICE) and Session Initiation Protocol (SIP) to create an encrypted stream. Users can communicate
between any mix of iOS and OS X devices using FaceTime.
Note: FaceTime calling requires a FaceTime-enabled device for both the caller and recipient,
and a Wi-Fi connection. FaceTime over a cellular network requires iPhone 4s or later, iPad with
Retina Display or later, or iPad mini or later with cellular data capability. Availability over a cellular
network depends on carrier policies. Data charges may apply.
Siri
By simply talking naturally, users can have Siri send messages, schedule meetings, place phone
calls, and more. Siri uses speech recognition, text-to-speech, and a client-server model to respond
to a broad range of requests. The tasks that Siri supports have been designed to ensure that only
the absolute minimum of personal information is used, and that the information used is fully
protected. Siri requests and voice recordings aren’t personally identied, and whenever possible,
Siri functions are carried out on the iOS device, not the server.
Note: Siri may not be available in all languages or in all areas, and features may vary by area.
Internet access is required. Cellular data charges may apply.
Apple ID for Students
The Apple ID for Students program is for students under the age of 13. Apple IDs are requested
by the school or school district, and created by Apple after receiving from a parent or guardian
a signed Parent Privacy Disclosure and Consent form. This method complies with the Children’s
Online Privacy Protection Act (COPPA).
