About the Phone
Phone features on the computer include one speaker and three microphones for
noise cancellation. You can also use a hands-free kit or headset that supports
Bluetooth® wireless technology.
On WWAN models the phone feature is enabled by default and supports most
cellular radio access technologies for voice and data connections around the
globe. These features are certified by PTCRB, GCF, and all major US carriers.
After you turn on the phone and activate service with your wireless carrier, you can
customize the phone features and network settings in the Network & internet
section of the Settings app.
A dedicated PTT button on the left side of the unit is provided for use with
applications that support push-to-talk (PTT) functionality.
Note: WWAN radios support Network Information and Time Zone (NITZ) messages to
automatically set the system time.
