When you dial 711 while on AT&T’s network, the call is automatically sent to the TRS center for the state where you are located. This allows the relay operator to send any emergency calls to a public safety agency in your area.
When you dial 711 while roaming on a third-party’s LTE network, the call is sent to the TRS center serving the state that you name as your place of use. For example, a TRS user attending school out-of-state, spending the winter in Florida, or going on a long vacation, should change their place of use to their destination state. How to specify place of use
- Dial 711 to reach a TRS operator (typically, using a TTY device).
- Provide the TRS operator with the toll-free number for AT&T Customer Care 800.331.0500 and the preferred TRS state.
- The TRS operator will place the call to AT&T Customer Care and act as the intermediary to initiate your change in preferred TRS state.
