The trial leveraged Motive Entitlement Server (ES) and Telefónica Spain's infrastructure to expose Open Gateway Number verification CAMARA API with TS.43 Operator Token authentication mechanism. This service was integrated into Google's Firebase phone number verification service to enable SIM-based authentication via secure tokens.
"Security and simplicity are the core of our digital transformation," said Alexandre Harmand, Head of Networks, Telefónica. "Through number verification for authentication, we enhance user trust, reduce fraud, and improve the overall authentication experience for customers."
"This joint effort reinforces our leadership in Entitlement services," said Jeevithan Muttu, VP Product and R&D, Motive. "Operators can unlock new revenue streams through seamless app authentication as well as RCS enablement and secure business messaging."
For Telefónica, this trial supports its strategy to enhance customer authentication security while improving ease of use.
Operator interest in the GSMA Open Gateway initiative continues to grow. As of February 2025, 72 mobile operators had committed to GSMA Open Gateway APIs. These account for approximately 80% of mobile market share by connections, up from just over 65% in June 2024.
Security protection and fraud mitigation have been the most popular applications of GSMA Open Gateway APIs so far deployed by mobile operators and their partners.
Motive ES enables secure, SIM-based activation of rich messaging features while efficiently managing large-scale device provisioning. It also offers comprehensive functionalities that meet evolving business needs for primary and secondary mobile devices leveraging the latest Apple and GSMA TS.43 specifications, as well as automobile GSMA AiD.02.
