Phone Services

When you are using your device in the United States, you can configure CDMA (domestic) phone services for your device.

To access and change settings for domestic phone services:

1.Slide to the Settings tab, and then tap Wireless controls > Phone > CDMA Services tab.

2.Tap the service you want to change, and then tap Get Settings.

3.Tap OK after changing settings.

The following are some of the services that you can configure for your device:

Service	Usage
Location Setting	Allows the network to detect your current location using your device’s built-in
	GPS chip. This is especially useful in emergencies.
TTY Mode	Allows the use of a TTY (teletypewriter) device with the 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.
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 about roaming, see “Roaming” on page 143.
Time Synchronization	Allows the system time on your device to be synchronized with the time
	information of the mobile phone network.
Voicemail	Allows you to delete voicemail messages and clear the voicemail icon if it
	appears on the screen.
Roaming Alert	Enables sound alerts on your device so that you can be notified when your
	device enters or goes out of the network coverage area.
DDTM Mode	By default, voice calls take precedence over data. If, for instance, you are
	browsing the Web or streaming media, the data connection may be interrupted
	when you have an incoming call. To avoid interrupting the data connection, you
	can turn on DDTM Mode so that voice calls can be automatically sent to
	voicemail and the data connection will not be interrupted.
