TTY Mode On Smartphones: What It Means and How to Use It

What is TTY Mode on Smartphones?

TTY mode on the phone refers to Teletypewriter mode, a feature that allows communication for people with hearing or speech impairments. With this mode, a smartphone can connect to a teletypewriter device, enabling typed messages to be sent over phone lines.

In simple terms, TTY mode in mobile can be explained as a function that converts spoken words into text and sends them through a phone call. The receiver with a TTY device can read the text instead of listening to a voice. This makes communication easier for people who have difficulty hearing or speaking clearly.
