I have very very very bad eyes and I can not see anything very small. I do have glasses but I can not use them in the Fay light. Any cell phone I can not see to use and I know they can be setup for voice calling. But I do not think it will work that good with me. I have to talk to it and if something goes wacky I can not see it to fix it or reset anything. Do they have a watch that is a cell phone? Or something that you can put say 4 cell phone numbers to auto call? Or what do you think is a good thing to do?
