Phone Services	Usage

		LOCATION ON (your location can be detected)
		LOCATION OFF (your location cannot be detected except by 911)
Roaming	To better control roaming costs, you can set your device to roam only on certain networks. The Data
	Roam Guard also helps you to manage your roaming costs. For more information, see “Voice and
	Data Roaming.”
TTY Mode	Allow the use of a TTY (teletypewriter) device with the smart device phone for users who are
	visually or hearing impaired. Choose one of the following modes, depending on the operation mode
	that is supported by the TTY device:
		Full mode	Send and receive text during an ongoing call.
		VCO mode	Voice Carry Over mode, which allows users to send voice and receive text during an
			ongoing call.
		HCO mode	Hearing Carry Over mode, which allows users to send text and receive voice during
			an ongoing call.
		Off	Disable TTY mode, and send and receive voice during an ongoing call.
Internet	Initiate IOTA (Internet-based Over-The-Air provisioning) so that the network can provision your
	device with the required parameters (such as WAP parameters, roaming lists, etc.) for you to
	access all available services in a secure manner. Tap Start on the Phone: Internet screen to initiate
	provisioning.
Time Synchronization	Allow the system time on your device to be synchronized with the time information of the mobile
	phone network.
Plus Code Dialing	This allows easy dialing when making international calls. For more information, see “Customizing
	Plus Code Dialing.”
Roaming Alert	Enable sound alerts on your device so that you can be notified when your device enters or goes out
	of the network coverage area. By default, alert notification is disabled.
