Target Devices: Machine-to-Machine (M2M) devices.

Use Case: Designed for devices without direct human interaction, such as industrial equipment, smart meters, or connected cars.

Key Features: No User Interface, M2M devices often lack screens or user interfaces, so provisioning is handled entirely by the device and the backend systems.

Pre-provisioning: The eSIM profile is typically pre-loaded onto the device before deployment.

Remote Management: Profiles can be updated or changed remotely, but the process is more rigid compared to consumer devices.

Static Use Case: Once deployed, M2M devices often remain on a single network or profile for their entire lifecycle.

Limitations: It is not designed for frequent profile switching and has limited flexibility compared to consumer eSIM standards.

Target Devices: Consumer devices like smartphones, tablets, smartwatches, and laptops.

Use Case: Designed for devices that require frequent profile switching and user interaction.

Key Features: User-Friendly: Allows users to easily switch between carriers or plans using a QR code or app.

Multiple Profiles: Supports storing multiple eSIM profiles on a single device, enabling users to switch between them as needed.

Remote Provisioning: Profiles can be downloaded and activated over-the-air (OTA) without needing a physical SIM card.

Dynamic Use Case: Ideal for frequent travellers or users who want flexibility in choosing carriers.
Examples: iPhones (starting from iPhone XS, XR, and later), Google Pixel devices, Apple Watch and Samsung Galaxy Watch.

Advantages:
Greater flexibility and convenience for end-users.  Simplified carrier switching.

Target Devices: IoT (Internet of Things) devices.

Use Case: Designed for IoT devices that require scalable, secure, and efficient eSIM provisioning and management.

Key Features; Scalability, Supports large-scale deployments of IoT devices, such as smart meters, asset trackers, and agricultural sensors.

Remote Provisioning: Enables over-the-air (OTA) provisioning and management of eSIM profiles, even for devices in remote or hard-to-access locations.

Simplified Management: Focuses on automating the provisioning process for IoT devices, which often lack user interfaces.

Interoperability: Ensures compatibility across different manufacturers and carriers.

Security: Incorporates robust security measures to protect the provisioning process.

Advantages: Tailored for IoT use cases, where devices may have limited power, connectivity, or user interaction. Enables seamless deployment and management of IoT devices at scale.
