All Optimum Mobile phones are hearing-aid compatible (HAC).

Hearing Aid Compatibility (HAC)

The Federal Communications Commission (FCC) has adopted hearing-aid compatibility (HAC) requirements for digital wireless phones. Below are the HAC ratings for phones that are hearing-aid compatible under FCC rules.

There are two measures used. First, all digital handsets have a rating for their ability to reduce interference with hearing aids operating in acoustic mode – from M1 to M4, with M4 being the best. Handsets are also rated – from T1 to T4 – for their ability to operate with hearing aids that contain a telecoil (a tightly wrapped piece of wire that converts sounds into electromagnetic signals) and operate in inductive coupling mode. The FCC considers mobile handsets to be hearing aid compatible if they are rated at least M3 for acoustic coupling and at least T3 for inductive coupling.

Real Time Text (RTT)

If you have a hearing or speech disability and want an alternative to TTY for communicating using wireless devices, you can use RTT. This feature uses a mix of text and voice. As you type messages in your device, text will display on the receiving device. This is great for everyday communication and is compatible with emergency calls in the same way that TTY is today.

To enable RTT, visit the Accessibility section from your phone’s Settings.

In areas where texting to 911 is available, customers can text 911 directly from their wireless device or call 911 using real-time text (RTT) on RTT-capable handsets. For more information on RTT visit

Text Telephone (TTY)

Optimum Mobile provides Voice Over LTE (VoLTE) and WiFi Calling voice services therefore calls from a TTY will not work. Optimum Mobile recommends that instead of TTY, that you use internet-based Telecommunications Relay Service (TRS) such as Video Relay Service (VRS), Internet Protocol Relay Service, or IP Captioned Telephone Service, that allows persons with hearing or speech disabilities to place and receive telephone calls.
