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.Â
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.Â
