Find wireless phones with TTY compatibility or built-in RTT

Have a hearing or speech disability? You can still stay in touch on the go with wireless phones that work with TTY or have built-in real-time text (RTT).

About our TTY-compatible wireless phones

When you and another person have teletypewriter (TTY) devices, you can communicate visually using one- or two-line electronic displays that work with TTY-compatible wireless phones.

A TTY-compatible wireless phone has a 2.5-millimeter port for the audio jack connector on the TTY device.

TTY limitations for 911 calls

Keep in mind that you can’t make 911 calls with TTY devices1 over Wi-Fi Calling.1 Have to reach 911 services? You can:

  • Use real-time text (att.com/RTT) instead of TTY.
  • Call 911 directly using TTY from a wireless phone over the cellular network or from a landline telephone.
  • Text 911 directly from a wireless device (in areas where text-to-911 is available).
  • Use relay services to place a TTY or Captioned Telephone Service (CTS) call from a wireless phone over the cellular network or from a landline phone.
  • Use relay services to place an IP Relay or IP CTS call over a cellular data or other IP network.
