Chapter 4 — Use the Phone
About the Phone
Phone features on the computer include a speaker and a microphone.
You can also use a Bluetooth headset or hands-free kit. The phone
feature is enabled by default.
The WAN radio in your computer determines the supported network
After you turn on the phone and activate service with your wireless
carrier, you can customize the phone features and network settings in
the Wireless & Networks section of the Settings app.
Note: Both WWAN radios support Network Information and Time Zone
(NITZ) messages to automatically set the system time.
