Aduna Partners with AT&T, T-Mobile, and Verizon to Replace SMS Security

The new service, dubbed Number Verification, confirms a user’s identity by authenticating the connection between a mobile device, its SIM card, and the carrier network in real time. Unlike SMS codes, which can be intercepted by sophisticated social engineering or AI-powered scams, this possession-based method functions without the latency or security gaps inherent in text messaging. Previous attempts at similar technology often failed to bridge the gap between Wi-Fi users and cellular networks, but Aduna claims its latest iteration works seamlessly across all major operating systems and connection types.

This rollout arrives at a critical juncture for U.S. mobile security, following a year in which consumers reported $15.9 billion in fraud losses. Aduna CEO Anthony Bartolo describes the mobile number as a "digital passport," noting that the platform allows developers to bypass legacy authentication hurdles while simultaneously reducing login friction. Representatives from AT&T, T-Mobile, and Verizon emphasized that the initiative leverages standardized network APIs to offer businesses direct access to carrier-level trust. By moving authentication directly into the network infrastructure, the companies aim to provide a more resilient defense against man-in-the-middle attacks while streamlining the digital user experience.
