Hearing Aid Compatibility (HAC)
Mobile wireless service providers and device manufacturers are required to offer handsets that are compatible with (do not cause interference with) hearing aids and cochlear implants.

There are two handheld measurements used.
Acoustic coupling mode: from M1 to M4, with M4 being the best.
Inductive coupling mode: from T1 to T4, with T4 being the best.

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.

United Wireless encourages you try, before you buy, and ask any one of our retail service representatives for assistance. It's important for you to find the best match with your hearing aid. All United Wireless stores have hearing aid compatible handsets available to try. Below is a list of hearing aid compatible devices and their HAC ratings offered by United Wireless.
