The challenge
One of South Asia’s largest mobile operators faced surging A2P and P2P SMS volumes but was constrained by a legacy messaging stack:
- Traffic bottlenecks - built for 150M messages/month, unable to handle peak surges.
- Security gaps - minimal filtering left subscribers exposed to spam, phishing, and CLI spoofing.
- High OPEX due to separate SMS, USSD, and firewall hardware - increased cost and complexity.
- Slow partner onboarding - manual routing changes delayed global partner launches.
The solution
We deployed a next‑generation Prime Messaging platform, a unified, API‑ready hub to scale traffic, enhance security, and streamline operations:
- Centralized SMS routing - unified inbound/outbound traffic via intelligent hub
- Real‑time firewall protection - 15+ advanced filters blocked spam and fraud threats
- Secure A2P gateway - SMPP access for safe enterprise messaging (OTPs, alerts, campaigns)
- Unified dashboards - 20+ real‑time reports for traffic and security visibility
- Role‑based access control - centralized permissions and single sign‑on for teams
The outcome
- 12× messaging scale — from 150M to 1.8B messages/month.
- 1,200 TPS throughput — supporting peak campaign bursts.
- Proactive threat defense — CLI filtering and dynamic firewall rules.
- Lean infrastructure — 2‑server setup replaced fragmented legacy hardware.
- Faster partner go‑live — onboarding in hours instead of weeks.
- 99.999% uptime — active‑active redundancy and DB replication ensured reliability.
