Hearing Aid Compatibility (HAC)
Last updated: March 2026
In accordance with FCC regulations (47 CFR § 20.19), S Mobile Wireless provides the following hearing aid compatibility information for all currently offered wireless handset models. This information is updated regularly to comply with FCC Form 855 website posting requirements.
Understanding Hearing Aid Compatibility Ratings
ANSI C63.19-2019 Standard
The 2019 ANSI Standard does not use the M/T rating system. Instead, devices must meet or exceed a single threshold for each type of test (i.e., "PASS") and must meet volume control specifications. The "conversational gain" measures acoustic gain — how loud sound is compared to a normal, face-to-face conversation. To pass, a phone must have at least 6 dB of conversational gain with a hearing aid, and either 6 dB (if tested under FCC waiver DA 23-914) or 18 dB without a hearing aid.
ANSI C63.19-2011 Standard
The 2011 ANSI Standard uses the M/T rating system. "M" refers to radio-frequency (RF) emissions — the higher the M rating, the more likely the device works well with hearing aids in microphone mode. "T" refers to telecoil coupling — the higher the T rating, the better the device works with hearing aids in telecoil mode. A device is considered hearing aid compatible if rated M3 or M4 (acoustic coupling) and T3 or T4 (inductive coupling).
Bluetooth Coupling Technology
Many modern phones support Bluetooth-based audio streaming directly to hearing aids. Technologies include ASHA (Audio Streaming for Hearing Aids), LE Audio / HAP (Hearing Access Profile), and Made for iPhone (MFi) hearing aid connectivity. Check with your hearing aid manufacturer to confirm compatibility.

Important Information
All handset models listed above have been tested and certified for use with hearing aids for some of the wireless technologies that they use. However, there may be some newer wireless technologies used in these phones that have not been tested yet for use with hearing aids. It is important to try the different features of the phone thoroughly and in different locations, using your hearing aid or cochlear implant, to determine if you hear any interfering noise.
Hearing loss and hearing aids are highly individualized. Results will vary depending on the user's hearing aid and hearing loss. If your hearing aid happens to be vulnerable to interference, you may not be able to use a rated phone successfully. Trying out the phone with your hearing device is the best way to evaluate it for your personal needs.
For devices certified under the 2019 ANSI Standard, the conversational gain values displayed represent the lowest rating assigned to the handset model for any covered air interface or frequency band.
Devices noting "FCC waiver DA 23-914" have had their volume control performance evaluated according to the FCC's limited waiver, which allows a reduced conversational gain threshold without a hearing aid (6 dB instead of 18 dB).
