Is there any cell phone for Tmobile that is accessable for the blind?

I can see seom but net well at all. I like to text especially to my children as that is about the only way you can get a hold of them..lol. ANyway, I need a phone that will speak to me. I can see some short textx, but when someone sends a novel I cannot se it. ALso, I have some trouble navigating the menu for special functions and such also, sometimes i have trouble seeing the phonebook when I am looking up numbers that Ido not call often. T mobile does not list any special phones on thier site, but I though aomeone may have a good idea of what to do. I have heard of special software for cell phones, but its really really expensive and I am not sure what is compatible with what. Thanks all in advance!
