• Fraud Prevention: A bank subscribes to the roaming status updates to detect unusual device activity. If a device attempts to access an account from a different country and is not roaming, a fraud alert is triggered automatically without the need for continuous checks.
• Content Restrictions: A streaming service subscribes to roaming updates to ensure users are only able to view content within authorized regions. When the device roams into a different country, the system is automatically notified, and the traveller is restricted from accessing location-based content.
• Advertising: An advertiser subscribes to roaming status events to ensure ads are displayed only in specific countries or regions. When a device enters a new country, the system is notified, and the ad campaign is adjusted accordingly to match the user’s location.
