If you are deafblind, or have impaired vision and/or hearing, myMMX® db is a service designed especially for you. It features additional adaptability for your individual needs; the system can be used together with braille displays, screen reading and magnification software.

myMMX® db is available in two versions. One version for the computer with high-definition video, text telephony and audio, and another version for the iPhone and iPad if you only want to use text in your calls.
