USE THE PHONE
You can use the phone feature to make and receive phone calls as well as transmit
data through wireless wide-area networks (WWANs).
Note: Phone features are only supported on CT40 WWAN models (CT40-L1N).
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.
On CT40 WWAN models the phone feature is enabled by default and supports all
cellular radio access technologies (2G, 3G, etc.) 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 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.
Add or Switch Between Network Carriers
The SDR radio in the CT40 WWAN model makes it easy for you to add carriers and
switch between them as needed.
Use the Carrier Selection app to quickly change your WWAN radio network carrier.
1. Swipe up from the bottom of the Home screen to access all apps.
