I only have a text phone. I'm worried if i have to call 911 they will not answer me. I'm deaf. When I had my last heart attack I called 911 and talked to whole time I was on the phone. when the paramedics got here they asked why didn't I answer any of the questions the person asked. They told me i had to listen. Now is't that funny. I, who can not hear a sound, should know when to stop talking so the person could ask me questions. So be thankful you can use your phone for both text and talk.
