Abstract: While a mobile wireless device (102) operates in a home region (106), the mobile wireless device (102) displays public broadcast messages in accordance with the default broadcast message display settings (244) for the home region (106). In the event that the mobile wireless device (102) transits to a different region (110) for which region-specific broadcast message display settings have not already been configured, the mobile wireless device (102) queries a user to configure the broadcast message display settings (244) to be used for the new region (110). The display settings for a given region may be stored such that when the mobile wireless device (102) enters a region previously visited, the previously-configured display settings for the previously-visited region may be automatically implemented without user prompting.
