3. What If Apps Could Talk to the Network? Open Gateway A P I D A Y S
4. 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.

5. Why This Matters Now Open Gateway A P I D A Y S
6. 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
7. What is Open Gateway? Open Gateway A P I D A Y S
8. 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. What is Open Gateway A P I D A Y S OPERATOR X A P I S | D E V E L O P E R S & B U S I N E S S E S H Y P E R S C A L E R S , A G G R E G A T O R S & I N T E G R A T O R S C O N S U M E R S D I G I T A L S E R V I C E S O P E N G A T E W A Y P L A T F O R M OPERATOR Y
9. 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.
