When a mobile device is positioned in a first coverage area with first service parameters, it is determined that the mobile device is likely to enter a second coverage area with second service parameters. The mobile device has access to map data while in the first coverage area and the second coverage area. If it is determined that the first coverage area is more favorable to data transfer than the second coverage area using the service parameters, a request for map data for rendering a map of the second coverage area is generated when the mobile device is within the first coverage area, and prior to receiving a request to view the map of the second coverage area on the mobile device. The map data is received and stored on the mobile device for subsequent rendering.
