• Emergency Services: An emergency application subscribes to reachability notifications of critical response team members. If a team member’s device becomes reachable via SMS, the system can trigger an SMS alert, ensuring the responder gets the message despite potential data connectivity issues.
• Customer Support Platforms: A customer support platform checks the reachability of travellers through SMS before attempting to send a message or support ticket. If the device is reachable via SMS but not data, they ensure that only SMS-based communication is attempted.
• IoT Devices: A fleet management system queries the reachability status of IoT devices in vehicles. If a device is reachable via data, the system can proceed with real-time monitoring. If it’s reachable only via SMS, the system may reduce the frequency of data updates or switch to less data-intensive communication methods.
• Fraud Prevention: Verify that a customer’s mobile device is reachable before trusting calls or other communications that appear to originate from that device
