Text Messaging Device For the Hearing Impaired?

spaceball1 asks: "I was in the army and served in Iraq — one of the side effects being some permanent hearing loss. I now wear hearing aids all of the time, in both ears. Talking on a cell phone has become nearly impossible. I have considered moving to a device more geared towards text messaging, but they are all very expensive and have a lot of the features that I will never use. Are there any devices out there that are geared only towards simple text messaging? The No-Frills-Cell-Phone concept has been largely ignored in the US; does a No-Frills-Text-Messaging device exist?"
