Besides, should TTY be on or off?

So if you don't use a teletypewriter, it makes sense to keep the setting switched off in order to have access to your phone's full functionality. There are usually four settings to choose from, TTY Off, TTY Full, TTY HCO and TTY VCO. TTY Off is fairly straight forward, as it means TTY Mode is not enabled at all.

Also Know, is TTY still used today? Today, TTY relay services, the original and now “traditional” relay service, can be reached by anyone by dialing 711 from a telephone or TTY.

In respect to this, how do I use TTY on my phone?
