Phone Services Usage
Location Setting Allow the mobile phone network to detect your current location via your device's built-in GPS chip.
This is especially useful in times of emergency.

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:
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.

of the network coverage area. By default, alert notification is disabled.
