TTY mode is a feature available on mobile phones that allows individuals with hearing or speech impairments to communicate through text over regular phone calls. TTY stands for "teletypewriter," which was initially developed for people with hearing or speech difficulties to communicate by sending typed text over standard telephone lines. TTY mode includes several settings, such as TTY Full, TTY HCO (Hearing Carry Over), and TTY VCO (Voice Carry Over) .
- TTY Full allows for text-only communication.
- TTY HCO and VCO allow for a combination of voice and text, catering to those who can speak but not hear and vice versa.
To use TTY mode on a mobile phone, you need to select "TTY mode" from the "Call" menu and then choose the desired TTY mode. The steps to enable TTY mode may vary slightly depending on the phone model, but it is generally found in the phones settings under "Call settings" or "General settings". It is important to note that if TTY mode is on, some mobile phones may lose the ability to take or make voice calls, and some other features of the phone may also not work as expected.
