Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may transition between a real-time texting (RTT) mode and a text teletypewriter (TTY) mode and vice versa, on a user equipment (UE). A UE may make a determine to transition between two texting modes while coordinating the transfer of text data between the different modes. Some wireless communications systems may also transition a UE between a packet switched network and a circuit switched network without loss of signal and consistent text data delivery during the communication without losing the text data during the transition between the two coverage areas. Transitioning between modes and networks may provide a user with interoperability and the benefit of conveniently switching between two modes without service interruption.
