thank you!!!!! have much trouble with technology. don't want waste money! Big headaches with how to work all this stuff!The bigger problem is cellular phone, it have nothing with TDD. Thru my experience from my relation who are hearing, they do have problem with cell phone by try connect strong. However, in TTY mode, it required high "wave" to catch the communicate. You know?
However, just make sure and look careful on cell phone products which are available in TTY mode.
Biggest support on TTY mode are from AT&T.
