Claro, Telecom, and Telefónica presented their APIs for the local market and highlighted the opportunities for collaboration and new partnerships within the digital ecosystem.
GSMA Open Gateway, the global mobile industry initiative aimed at simplifying the development of digital applications and services, keeps making progress in Argentina. At a forum convened by the GSMA, the global leader of the project, operators Claro, Telecom, and Telefónica detailed the advancement of their APIs and discussed how standardization can transform mobile networks into open platforms for the digital ecosystem
GSMA Open Gateway is a standard through which operators provide developers with a series of network functions that are used to create applications and services capable of operating seamlessly on all devices, regardless of the country or operator. This is achieved through unique access points, the APIs (Application Programming Interfaces), which serve as gateways to network capability information. APIs are available through the CAMARA repository, an open-source project by the GSMA and the Linux Foundation.

In line with the global trend, the first APIs developed within the framework of GSMA Open Gateway in Argentina are focused on combating fraud and digital scams. They include:
• SIM SWAP, which allows recent SIM card changes to be verified;
• Device Location, which provides precise information about the location of a device;
• Device Status, which indicates whether a device is roaming and in which country;
• Number Verification, which checks that a phone number is associated with a certain device.
By providing key information in real time, these APIs are valuable in detecting and preventing fraud in financial transactions, making banks and fintech companies among the first interested vertical clients.
“Claro Argentina is firmly committed to collaborating on and promoting the GSMA’s global initiative, Open Gateway. We have long been adding tools to strengthen the digital environment, fostering innovative practices and adopting the best technologies to create a safer environment for both businesses and consumers. We are part of the first operational Open Gateway applications in the country focused on fraud and digital scam prevention; additionally, we bring extensive regional experience to continue advancing in this area,” stated Marcelo Guglielmucci, Corporate Value-Added Services Manager, Claro Argentina.
“At Telecom, we drive innovation by providing solutions that address the market’s most pressing needs. The first APIs we developed under the Open Gateway framework, such as SIM Swap, Number Verification, Device Status, and Device Location, deliver key value in security and anti-fraud for industries like fintech and financial services. These tools offer active protection through secure, reliable, and standardized authentication processes, helping to drastically reduce fraud in a constantly growing digital environment, aligning us with industry demands,” highlighted Alejandro Martinez, Business Owner of Connectivity, Telecom Argentina.
“Telefónica is working in a unified and consistent way in the country, alongside other operators, to implement Open Gateway—a concept that the Group championed back in 2023 when it was still relatively unknown. We are aligned with the country’s development plan, focusing on launching anti-fraud and online identity services. Through Open Gateway, we will enhance existing services and contribute to the creation of new possibilities, thanks to the company’s capabilities,” noted Gonzalo Fliguer, Regional Product Owner Advertising, Open Gateway & Big Data, Telefónica Hispam.
Alejandro Adamowicz, Director of Technology and Strategy for Latin America, GSMA, concluded: “GSMA Open Gateway is accelerating its progress in Latin America. All countries in the region now have at least one operator integrated taking part in the initiative, representing over 90% of total users. With Claro, Telecom, and Telefónica, Argentina is fully entering the Open Gateway era, ensuring 100% coverage of connections in the country.”
Since its launch at MWC Barcelona 2023, more than 64 mobile operator groups representing 277 networks and three quarters of mobile connections globally now participate in the initiative alongside many of the world’s leading technology companies. In Latin America, last November, Brazil became the first market with multi-operator APIs integrated into GSMA Open Gateway. To date, in addition to Argentina and Brazil, the GSMA is leading the implementation of APIs in 5 other countries in the region.
