Open Gateway / CAMARA / TS.43: what they mean for SNA

As the market moves beyond SMS OTP, open standards and operator frameworks are becoming increasingly important to the future scale, interoperability, and reach of Silent Network Authentication.

Why this matters

As more enterprises explore replacing SMS OTP with Silent Network Authentication, the conversation is moving beyond individual APIs and toward the frameworks and standards that will help SNA scale across markets, operators, and platforms.

That is where Open Gateway, CAMARA, and TS.43 become important.

They matter because buyers do not just want a technical capability. They want confidence that the ecosystem is moving toward a more interoperable and scalable model for mobile-based authentication.

 

  • Open Gateway

    • Open Gateway is a GSMA-led industry framework designed to make operator capabilities easier to access through common APIs. For enterprises evaluating SNA, this is important because it supports a more standardized and scalable way to consume mobile network capabilities rather than relying only on fragmented, market-by-market implementations.

  • CAMARA

    • CAMARA is the open API initiative helping define common telecom API standards across the ecosystem. In the context of Silent Network Authentication, CAMARA matters because it helps move the market toward more consistent API structures and a better developer and enterprise experience. For buyers, that means easier comparison, easier integration, and a clearer route to broader adoption over time.

  • TS.43

    • TS.43 is relevant because it points toward improved support for scenarios that have historically been harder for SNA, especially where users are not directly on cellular data. That makes it important to the long-term evolution of SNA, because one of the key questions in the market is how to improve coverage and usability across more real-world device and network conditions.

What this means for enterprises

For enterprises, these developments are a strong signal that SNA is not just an isolated product trend.

It is part of a broader shift in how the industry is thinking about phone-number-based authentication, mobile identity, and the replacement of SMS OTP.

That does not mean buyers need to wait for the ecosystem to become perfect before acting. It means they should choose partners who understand both today’s practical rollout reality and the direction of travel of the wider market.
