At a headline level, the global A2P SMS market appears healthy. Analyst forecasts point to steady expansion – from approximately $71 billion in 2024 to nearly $96 billion by 2029. Yet for many MNOs, this growth story feels disconnected from day-to-day reality.
Nowhere is this growth more visible than the APAC market. Mobile-first populations, fast-moving digital economies, and large-scale national payment initiatives have made the region the primary engine of global A2P traffic.
While the “international superhighways” – the global hubs and aggregators – are seeing traffic surges of up to 36%, operators on the ground are often managing a flat or even declining volumes, increased volatility, and mounting pressure on margins. The result is a widening gap between where growth is reported and where revenue is actually defended.
This is the A2P paradox: global growth is real – but it increasingly feels like a local fight.
In this blog post, our messaging experts unpack the data behind this divergence, explaining why APAC has become the epicenter of both opportunity and risk, and explore how next-generation telco capabilities are reshaping the future of authentication.
A Tale of Two Realities in A2P Traffic
When you compare industry-wide forecasts with traffic observed at interconnect and operator levels, the disconnect becomes clear.
The Hub View
International aggregators and global messaging hubs continue to report strong year-over-year growth. Acting as consolidation points for global enterprise traffic, they benefit from scale, routing concentration, and traffic aggregation—making growth appear both consistent and predictable.
The MNO View
For national operators, particularly in high-growth regions, the picture is far less stable. In direct year-on-year comparisons (Q3 2024 vs. Q3 2025), several major regional MNOs recorded 2–6% declines in average daily A2P traffic, once statistical outliers were removed.
The implication is critical: Growth is not disappearing – it is consolidating upstream.
For MNOs, the challenge is no longer just about capturing incremental growth. It is about defending existing revenue, maintaining pricing integrity, and preventing value leakage through grey routes and bypass.
APAC: Scale, Growth – and Extreme Volatility
Asia-Pacific remains the engine room of global A2P messaging. Mobile-first populations, rapid digitalization, and national payment ecosystems such as UPI (India), QRIS (Indonesia), and PayNow (Singapore) continue to drive massive volumes of authentication and notification traffic.
But at operator level, this “growth” often masks significant instability.
Many APAC MNOs process enormous message volumes, yet experience sharp, multi-million message swings driven by:
- Promotional bursts
- Fraud-driven traffic inflation
- Short-term enterprise campaigns
At the same time, competition for OTP traffic—the economic backbone of A2P—is intensifying.
While SMS remains the most universal and reliable authentication channel globally, in-app and OTT-based authentication is gaining ground, particularly where “super-apps” dominate consumer behavior.
| Market | Estimated SMS Share | Authentication Pressure |
|---|---|---|
| India | 90%+ | Protected by regulation |
| Singapore | ~80% | Bank-led security models |
| Thailand | ~40% | Strong OTT competition |
| Philippines | ~50% | High super-app adoption |
For MNOs, this creates a dual challenge: protect SMS revenues today while preparing for a post-SMS authentication future.
Beyond the Pipe: From SMS to Telco APIs
The most consequential shift in A2P is not about volume – it’s about trust and identity.
SMS OTPs are increasingly criticized for their exposure to phishing, SIM-swap abuse, and large-scale SMS Pumping fraud. Enterprises still rely on SMS because of reach and reliability, but the security conversation is clearly evolving.
This is where telcos have a unique opportunity to move up the value chain.
Through initiatives like CAMARA, operators are beginning to expose network-verified identity capabilities via standardized APIs. In late 2025, this vision became tangible with the launch of a regional telco alliance in Southeast Asia, involving Indonesia’s three largest mobile operators.
The objective: replace visible OTPs with Silent Authentication (Telco Verify).
How it works
Instead of sending a one-time code, an enterprise application queries the network directly:
Does this user, on this device and IP address, genuinely own this phone number?
The MNO validates the request using real-time network intelligence and returns a secure, instant response—no codes, no user interaction, no phishing risk.
This capability is:
- Phishing-proof
- Frictionless for end users
- Impossible for OTT players to replicate
Most importantly, it positions the MNO not as a transport layer, but as a trusted identity provider.
Conclusion
For national MNOs, the future of A2P will not be defined by raw traffic growth alone. It will be defined by control, intelligence, and trust.
Operators that succeed will be those that:
- Secure the channel
AI-driven firewalls and advanced traffic intelligence are essential to eliminate grey routes, prevent fraud, and ensure every legitimate message is monetised. - Manage volatility, not just volume
Predictive analytics and real-time controls are key to handling traffic spikes while offering smarter pricing and SLAs to enterprise customers. - Pivot toward identity services
Network-verified APIs represent a defensible, high-margin revenue stream that leverages a telco’s unique assets.
The A2P market is evolving fast. The winners won’t simply be the networks carrying the most traffic—but the ones providing the most trust.
