The iPhone is now even more accessible for Americans who are deaf or have a hearing or speech disability. Today, AT&T Inc. (NYSE:T) announced a new Text Accessibility Plan (TAP) for iPhone, designed to give iPhone customers with disabilities the choice of unlimited text messaging, Web browsing and easy access to e-mail for $40 a month.

“Our Text Accessibility Plan allows customers who are deaf or have hearing or speech disabilities to literally tap out their communications on the go,” said Carlton Hill, vice president of Product Management, Voice Products and Affiliate Marketing for AT&T’s wireless unit. “Now with TAP for iPhone, users can tap, flick and pinch the innovative Multi-Touch touch screen for a completely new world of functionality.”

This new plan is available to new and current iPhone users with qualifying disabilities through AT&T’s National Center for Customers with Disabilities (NCCD). To qualify for the iPhone TAP, customers must complete an application for eligibility. The form is available for download at http://www.wireless.att.com/about/disability-resources/text-accessibility-plan-for-iphone.jsp.

During the iPhone activation process, customers sign up for a standard iPhone voice and data plan. After the iPhone is activated, customers can e-mail, fax or mail the eligibility form back to the NCCD to change their rate plan to the TAP for iPhone.

Current iPhone customers who qualify may also submit the NCCD application to request the TAP for iPhone. Customers can contact the AT&T NCCD with questions at 866-241-6568 for voice calls or 866-241-6567 for TTY calls.

AT&T offers TAP plans to qualifying customers for use with most handsets across AT&T’s portfolio. The NCCD also helps AT&T customers with disabilities with a variety of applications that aid in wireless communications. These include Mobile Magnifier, which enables individuals who have low vision or are blind to zoom in on the screen and Mobile Speak, which reads aloud menu options.
