This tweak enables TTY support for all your installed SIM cards on your device.
What is TTY and how to use? -
TTY on iPhone
Note that if the peer of your call haven't set up TTY, they will only hear random noise when you are entering any text. So if they are not in a country / using a carrier that supports TTY and haven't installed this tweak, your call would be meaningless (but fun) to them.
