Use Case 2

Postpaid Funding for Application 2 Phone (A2P) Messaging (SMS) Traffic

The A2P messaging industry covers automated business-to-consumer communications delivered through SMS, WhatsApp, and RCS: alerts, marketing, one-time passwords, and customer notifications. E-commerce and banking pull growth, as both sectors need secure authentication and real-time engagement. SMS commands the largest share of spend even as OTT platforms gain volume.

Security and compliance (2FA, fraud prevention), platform consolidation among CPaaS leaders like Twilio, Sinch, Infobip, and Route Mobile, and regulatory oversight shape market dynamics. The market runs to multi-billion dollar scale and is projected to exceed $90–125B in the early 2030s, with AI-driven personalization and channel orchestration driving further investment.

Aggregators and carriers use Least Cost Routing (LCR) to select the cheapest compliant paths in real time, balancing cost against delivery quality. Grey routes, which disguise A2P traffic as P2P to cut costs, create blocking, lower delivery rates, and fraud exposure.

Price gaps between premium white routes and lower-cost grey routes create arbitrage. Blended pricing reduces enterprise costs but leaks revenue for mobile network operators, pushing stronger enforcement and a shift toward verified routes and OTT alternatives.

A2P invoicing runs on per-message rating and detailed charging models. CDRs track sender IDs, destination networks, delivery status, message type, and charges, enabling accurate billing, 10DLC compliance fees, and pass-through termination charges. Carriers need rating, routing, and trading platforms to preserve margins across diverse rate decks.

SMS firewalls shape settlement economics by filtering grey traffic and monetizing legitimate A2P delivery. Operators run AI-driven security to detect AIT fraud, enforce sender verification, and bill only authorized traffic.
