It is time for deaf and hard of hearing TTY users to assess if and how they will participate in this strong trend. Here is some practical information that may help you in your decision-making.
Cell phones are like little radios that communicate with towers scattered around our landscape.
Each tower covers an area around it, called a cell. When you are using a phone and moving between cells, the system can find you and move your call to the next cell s tower. The industry prefers the term wireless phones for its newer products, but you will also see cellular used often. TTYs will work reliably with cellular phones that are analog. Most digital wireless telephone systems garble TTY at the present time, but this situation is changing.
