Abstract
Systems, products, and methods are disclosed for identifying a roaming indicator to be displayed on a mobile device that is in a given roaming situation and for determining a set of services that are available to the device. One variation of the method includes encoding within an ERI (enhanced roaming indicator) property two values that are respectively defined in a first portion of the ERI property and a second portion of the ERI property. The first portion of the ERI describes a visual roaming indicator that is to be presented on a mobile device. The second portion of the ERI describes a set of services that are available to the mobile device. A decoding method includes identifying an ERI value that is applicable given the roaming status, referencing a binary version of the ERI value, and inspecting a designated portion of the ERI value that indicates which services of the set of services are available.
