  3. Open Gateway Your app knows the user’s device. But does

    it know the network? • Most apps know the user’s device, browser, or location — but they’re completely blind to the mobile network underneath. • What if your app could verify identity, detect fraud, or boost performance — directly via the network, without asking the user? What If Apps Could Talk to the Network? +-----------------------------+ | Traditional Apps | +------+-----------------------------+ | User | 📱📱 Device + Browser | +------+-----------------------------+ | Auth | � SMS OTP ,Form-based login | +------+-----------------------------+ | KYC | 📝📝 Manual form matching | +------+-----------------------------+ | QoS | 🚫🚫 One-size-fits-all QoS | +------+-----------------------------+ | View | 🔒🔒 No network awareness | +------+-----------------------------+ 🕳🕳 Traditional apps are blind to the network. Traditional Apps Telco-Aware Apps +----------------------------------+ | Telco-Aware Apps | +------+----------------------------------+ | User | 📱📱 Device + ✅ Verified MSISDN | +------+----------------------------------+ | Auth | 🔐🔐 Network-based verification | +------+----------------------------------+ | KYC | 🆔🆔 Telco-verified identity | +------+----------------------------------+ | QoS | 🚀🚀 On-demand programmable QoS | +------+----------------------------------+ | View | 📡📡 Talks directly to the network | +------+----------------------------------+ ✅ Telco-aware apps see, ask, and optimize with real-time APIs.

  4. Open Gateway The network is no longer a black box

    — and developers are finally invited in. • APIs have transformed industries — from payments and maps to identity and messaging. • But mobile networks have remained closed, complex, and off-limits to developers. • Today’s apps need more: verified identity, fraud prevention, low-latency, and personalized performance. • Telcos are shifting from infrastructure providers to programmable platforms. • Open Gateway marks a historic shift — giving developers direct access to network intelligence. • This is not just a new API. It’s a new frontier for digital experiences. Why this matters now +--------------------+------------------------+----------------------------+------------------------+ Year | 2005 | 2010 | 2020 | 2025 | Event | REST APIs emerge | Cloud & Comm APIs | APIs rule digital world | Telco APIs go global | | (Twitter, Flickr) | (AWS, Heroku, Twilio) | (Stripe, Auth0, Plaid) | → GSMA Open Gateway | +--------------------+------------------------+----------------------------+------------------------+ │ │ │ │ ▼ ▼ ▼ ▼ Developers get Backend & comms become Digital services run The network itself simple access to plug-and-play for all on programmable APIs becomes programmable web services — everywhere (finally!) A P I D A Y S
  5. Open Gateway Programmability is the new telco normal — and

    for the first time, developers are invited in. • Built with Developer-first mindset • Open Gateway is a GSMA-led initiative in the telco sector that seeks to transform the communications networks into platforms. • Open Gateway is openning up telco capabilities in an interoperable, intuitive and programmable way. • These capabilities are deployed through global and standardized APIs under the framework of CAMARA, the Open-Source project led by the Linux Foundation in partnership with the GSMA.

  6. Open Gateway _Connect → Expose → Operate_ • Globally aligned:

    GSMA brings global coordination & trust • Built for developers: CAMARA defines APIs anyone can use • Operationalized: TM Forum enables lifecycle, billing, assurance • Together, we turn telecom into a programmable platform. C.E.O of Open Gateway +---------------------+-----------------------------+-----------------------------+ | CONNECT | EXPOSE | OPERATE | | | | | +---------------------+-----------------------------+-----------------------------+ | Aligns global | Defines & hosts | Runs business | | telcos, cloud & | developer-ready network | models, lifecycles, | | devs under one | APIs via open source | SLAs, commercial flows | | framework | | | +---------------------+-----------------------------+-----------------------------+ Same APIs. Same rules. One Unified global network interface. A P I D A Y S
  7. Open Gateway Give your app a telco superpower — in

    just 3 steps From Zero to Hero: The Developer Journey +--------------------+ +----------------------+ +----------------------------+ | STEP 1: | | STEP 2: | | STEP 3: | | Learn the APIs | --> | Test in Sandbox | --> | Build & Launch | | (Use cases, docs)| | (Postman, curl) | | Telco-Aware App Features | +--------------------+ +----------------------+ +----------------------------+ | Transform your app from passive → proactive. With this your app knows: 📞📞 Verified MSISDN 🔐🔐 Fraud Detection 🚀🚀 On-Demand QoS From Zero (Before) → To Hero (After) ❌ No network awareness ✅ Full API-powered network control 🛑🛑 Blind to SIM or QoS 👁👁 Detect SIM swaps, boost quality of service 📱📱 Only device/browser logic 🧠🧠 Real-time telco intelligence inside ⌛ Manual fraud checks ⚡ Frictionless verification in seconds Your app used to run on the network. Now you can make it run with the networks. A P I D A Y S
  8. Open Gateway Mockup The Telefónica Open Gateway Sandbox is a

    secure technological testing environment, isolated and controlled by TELEFÓNICA, which offers you access to the Open Gateway APIs provided by the Telefónica Group Operators in the countries where they are available, as well as to any other TELEFÓNICA or Operator Authorized Material. In order to use the Sandbox you need to be registered in the Developer Hub or in the Partner Program. Sandbox A P I D A Y S
