Abstract
A method is provided that allows for prioritizing Push-To-Talk (PTT) service in a roamed network. PTT service is enabled for a mobile device at a first network. The mobile device roams to a second network that is of an older generation than the first network. It is determined that the mobile device has an active PTT subscription. PTT service is prioritized for the mobile device over circuit switched services on the second network.
