Why Teams Use The Radar

From SMS routing to fraud detection — carrier intelligence powers critical business decisions.

Smart SMS Routing

Route SMS messages through the optimal gateway based on carrier. Reduce delivery failures and cut costs by avoiding expensive cross-carrier routes.

Fraud Prevention

Detect VoIP numbers, virtual lines, and disposable phone services at sign-up. Block fraudulent accounts before they cause damage to your platform.

Lead Qualification

Enrich your CRM data with carrier and line type intel. Prioritize leads with real mobile numbers over VoIP or landline contacts for higher conversion rates.

Identity Verification

Validate phone numbers during KYC and onboarding. Ensure numbers are active, real mobile lines — not throwaway VoIP accounts used for fake signups.

Data Enrichment

Append carrier, line type, and geographic data to your existing phone records. Segment audiences by carrier for targeted marketing and improved deliverability.

Cost Optimization

Know the carrier before you send. Avoid wasting budget on undeliverable numbers and optimize per-message costs across different carrier networks.
