About the Phone
Activate the UMTS Phone
Dolphin CT50 Mobile Computer with Windows 10 IoT Mobile Enterprise User Guide
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, if present, is enabled by default.
The WAN radio in your computer determines the supported network
If your computer includes the UMTS/HSPA+ WAN radio, you can
connect to UMTS networks.
If your computer includes the Flexible Network Radio, you can
connect to CDMA or UMTS networks in all regions that support these
technologies. The Flexible Network Radio is a software-defined radio
(SDR) that can be configured for CDMA or UMTS depending on your
wireless communication needs.
Honeywell supports Verizon in the United States (only) as a CDMA
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.
Activating the UMTS phone on your CT50 is done the same way whether
your computer has the Flexible Network Radio or the UMTS/HSPA+WAN
