- Payment System Validation: A financial service provider uses this API to validate if a user’s phone number has active voice/SMS services before processing high-risk transactions. If the API returns “suspended” for Voice/SMS inbound, the transaction is flagged for manual review to prevent fraud or invalid transfers.
- Customer Service Troubleshooting: The user reported that they were unable to receive calls. Customer support queries the API and identifies that “Voice/SMS inbound” is suspended. The user reported that they were unable to make a phone call. Customer support queries API and confirms that ‘voice/SMS outbound’ is suspended. The user reported that they are unable to use the data service. Customer support queries API and confirms that ‘data service status’ is suspended.

Use Cases
Benefits
- Fraud Prevention & Risk Mitigation: By validating real-time subscription status (e.g., suspended inbound voice/SMS), the API enables financial systems to flag high-risk transactions requiring manual review, reducing fraudulent transfers and chargebacks.
- Efficient Customer Support: Automatically identifies service disruptions (inbound/outbound voice/SMS, or data) without manual network checks, accelerating troubleshooting and improving first-contact resolution rates.
- Operational Cost Reduction: Eliminates redundant IT/OT system audits by providing a unified data source for multi-domain (voice/SMS/data) status, cutting integration costs.
