Alternatively, we can design and implement our own user interface for your eSIM app. We focus on intuitive onboarding, QR code scanning, and profile management. It can provide a smooth user experience for our partners and clients. We can change or update any part of the design if needed.

Step 3: Building Provisioning Workflows

During the provisioning build phase, we develop secure workflows for remote SIM provisioning, carrier switching, and authentication. The specific workflow will depend on whether it is for consumer devices (SGP.22) or Industrial IoT (SGP.32). You can visit Spenza’s provisioning guide to learn more about it. The end-user typically initiates this workflow through an app or device settings.

Step 4: Testing with Carriers and Devices

Now is the time to collaborate with telecom operators and device manufacturers to ensure interoperability across multiple platforms. Most partners and clients support iOS, Android, Huawei, and custom feature phone-based operating systems.

• Step 5: Launching on Android and iOS

Done! You can deploy apps on both ecosystems, ensuring compliance with Apple and Google’s eSIM frameworks. eSIM frameworks are the technical & operational structures that enable remote SIM provisioning (RSP) for embedded SIMs (eUICCs). Frameworks involve servers (SM-DP+), device components (eUICC), and management apps (LPA), ensuring interoperability and security across networks.

Top Challenges in eSIM App Development

👉 Security Risks & Mitigation Strategies

eSIM apps handle sensitive user data (identity, network credentials, billing info). Do you have safeguards? Good. But you do not have it; this data could be exposed to cyberattacks. So, developers must implement end-to-end encryption, secure authentication (like biometrics or multi-factor), and regular security audits. If you complete this, users trust you and your compliance with privacy standards.

👉 Carrier Interoperability Issues

Different telecom operators use varying standards and configurations. So, seamless switching between carriers is complex, especially across borders. That’s why building apps with GSMA-compliant frameworks and APIs helps ensure smooth provisioning and switching. In this process, collaboration with carriers during development is critical to avoid fragmentation.

👉 Device Compatibility Limitations

Yes, not all smartphones, tablets, or IoT devices support eSIM even in 2026. Some users may still rely on physical SIMs, creating adoption barriers. Therefore, apps should include fallback solutions (like dual SIM support or hybrid provisioning) and clear communication to users about device requirements. (Although we do not recommend this as mandatory. Remember, 75 % of users will adopt eSIM by 2030.

👉 Regulatory Hurdles Across Regions

An encouraging development is that telecom regulations vary widely by country. Developers must comply with local laws and international standards (such as GSMA specifications). You do not know who will use your eSIM app. So, non-compliance can block rollout or lead to legal issues.

To resolve this, maintaining a compliance-first approach is our recommendation. It’s how our developers complete the steps of building your eSIM or white-label eSIM app.
