Touch tones (DTMF): Windows Phone 8X by HTC

Learn how to enable touch tones on the Windows Phone 8X by HTC.




Turn on / off touch tones (DTMF)


Your device can send a number to the network as dual tone multi-frequency (DTMF) tones. DTMF tones are used to communicate with automated systems that require you to type a number such as a code, password, or credit card number.


Although your phone can use DTMF tones (touch tones), there is no setting to turn them on or off. We’re sorry, but changing DTMF tones is not available on your device.
