Accessibility Policy

T-Mobile is committed to providing products and services that meet a variety of communication needs.

Hearing aid compatibility

Some hearing aid users may detect interference in the form of a buzzing, humming, or whining noise when using a wireless phone. The amount of interference experienced may vary due to immunity level differences of hearing aids.

A rating system (M1 through M4 for microphone or T1 through T4 for telecoil) is used to assist consumers with identifying handsets designed to be compatible with hearing aids. FCC rules require labeling of phones that receive a rating of 3 or 4, which are deemed to be hearing aid compatible. Phones that receive a rating of 3 or 4 usually cause the least amount of interference. Typically, the higher the M or T rating assigned to a phone, the less interference.

Although the rating system is not a guarantee, it is a useful tool for consumers to determine the most appropriate wireless handset.

For additional information about hearing aid compatibility with digital wireless phones, see the Hearing aid compatibility brochure and the FCC Guide.

Important Note:

These phones have been tested and rated 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 your phone thoroughly and in different locations, using your hearing aid or cochlear implant, to determine if you hear any interfering noise. Consult the manufacturer of your phone for information on hearing aid compatibility. If you have questions about return or exchange policies, consult your service provider or phone retailer.

Handsets with Wi-Fi or Voice Over LTE (VoLTE) calling capabilities may not have been tested for hearing aid compatibility in these calling modes.

T-Mobile TTY policy

TTY, also known as Text Telephone Device or Telecommunication Device for the Deaf (TDD), is a special device required at both ends of the conversation that enables people who are deaf, hard of hearing, or speech-impaired to use the telephone to communicate. TTY works by allowing people to type messages back and forth to one another instead of talking and listening.

The FCC requires digital wireless carriers to have the capability to transmit a call from a wireless phone that is connected to a TTY. While the FCC mandate pertains specifically to calls made to 9-1-1, the ability to make a call to 9-1-1 means that they can also complete a call to anyone, anywhere, provided the party on the receiving end of the call also has a TTY.

TTY on T-Mobile's network

T-Mobile’s higher speed data services, including LTE, support use of IP-based telecommunications relay services including Video Relay Service, IP Relay, and IP Captioned Telephone Service through providers of those relay services. T-Mobile recommends use of these relay services as the most effective means of placing assisted calls, including to 911. If a T-Mobile customer nonetheless wants to use a mobile TTY, T-Mobile’s GSM and UMTS cellular network is TTY compatible. All T-Mobile price plans and most handset features will work with TTY. Customers will need to visit a T-Mobile retail store or contact Customer Service for assistance with selecting the proper rate plan and service activation.

Customers should be aware that TTY does not work on voice calls that are placed over Wi-Fi or Voice-over LTE at this time. This means that TTY calls, including TTY calls to 911, cannot be made while using IP-based calling, including Wi-Fi Calling and Voice over LTE. Customers with communications disabilities who need to call 911 while using IP-based calling should use IP Relay, Video Relay, or IP Captioned Telephone Service to reach emergency personnel.
