Frequently Asked Questions – T-Mobile IP Relay

Who can use T-Mobile IP Relay products?

T-Mobile IP Relay products are designed for people who are Deaf, Hard-of-Hearing, DeafBlind or have a Speech Disability who wish to communicate with hearing callers from anywhere in the US or its territories using computer (web) or mobile devices.  FEDERAL LAW PROHIBITS the use of IP Relay Service by anyone other than REGISTERED users.  Note:  All calls are strictly confidential and no records of any conversations are maintained by T-Mobile.

Is registration required?

What is a Relay Operator?

A relay operator:

  • Delivers a confidential, transparent link between an IP Relay and hearing caller and is not part of the conversation
  • Must type everything heard from the hearing caller, including background noises to the IP Relay caller
  • Must voice the conversation by reading aloud everything typed by the IP Relay caller, including what is typed in parentheses to the hearing caller.

Will I be able to save and print my conversation?

Yes, the (web application) and mobile application includes the functionality to copy and email conversations.  You may then print your conversation.

Can I use IP Relay on a conference call?

 Yes, IP Relay may be used for conference calls when there are more than two callers.  One caller must set up the conference bridge or web conferencing platform and provide the dial-in number to all participants, including the IP Relay user.  The IP Relay user opens the IP Relay app and dials the conference bridge or web conferencing audio phone number.  Once connected to the Relay Operator, the IP Relay user provides the access number for the Relay Operator to join the call.  The IP Relay user may ask the other callers on the call to identify who is speaking for the Relay Operator to type everything heard.

Why can’t I save my conversation on the T-Mobile IP Relay website?

At the end of your conversation, there are three options:   Copy, Email or Done. 

  1. Click “Copy” and then paste into a document like Notepad or MS Word.
  2. Click “Email” and send to your preferred email address.  This method uses the default email application setup on the computer being used.
  3. Click “Done” to make another call or return to the “Make or Receive a Call” screen.

What does “END” mean after I finish my call?

IP Relay users may make subsequent calls and no need to disconnect with Relay Operator.  By clicking “End”, the IP caller will disconnect from Relay Operator.  An IP Relay user is given three options: “Copy”, “Email” or “Done”.  Conversation will not be deleted until one option is selected.  “Done” will delete the conversation and return the user to “Make or Receive a Call” screen.

Why can’t I change my font size and background color options for my conversation?

Web:  Window Preferences will magnify the font size or CTRL + will increase the entire website font size.  Display settings will change the background color and font color.

Mobile App:  Mobile device users can go to the iOS or Android accessibility features to update font size, bold text or invert colors.

What if I don’t like the scrolling?

Depending on the resolution of your computer display, you may want to try different Display settings and zoom levels.  Most people will find setting the Display Setting to "small" and the Window Preferences text size to 200% magnification helps eliminate scrolling and keeps the conversation text on the conversation screen. 

Users can also adjust the zoom level of the website in their browser by using CTRL (+) to increase and CTRL (–) to decrease the size of the website.
