What are the main types of eSIM activation

The main types of eSIM activation are:

1. **QR Code Activation**:
- **Process**: The carrier provides a QR code containing the eSIM profile information. The user scans the QR code with their device's camera, and the device automatically downloads and activates the eSIM profile.
- **Common Use**: This is one of the most common methods for consumers, as it is simple and user-friendly.

2. **Manual Activation**:
- **Process**: The user manually enters activation information, such as a code or credentials, provided by the carrier into the device. This method can be used when a QR code is not available or when the device does not support QR code scanning.
- **Common Use**: Typically used in situations where QR codes are not practical or when dealing with specific device settings.

3. **Carrier App Activation**:
- **Process**: The user downloads the carrier's mobile app, which guides them through the process of downloading and activating the eSIM profile directly through the app.
- **Common Use**: Many carriers offer apps that facilitate eSIM management, making this a convenient option for users who prefer app-based interactions.

4. **Remote SIM Provisioning (RSP)**:
- **Process**: The eSIM profile is downloaded and activated over the air (OTA) directly to the device via a remote server. This method involves the device connecting to the carrier's server to download the eSIM profile without the need for QR codes or manual entry.
- **Common Use**: Used for devices that support direct OTA provisioning, such as some smartwatches and IoT devices.

5. **Activation via Website or Customer Portal**:
- **Process**: The user logs into their carrier’s website or customer portal, where they can select their device and initiate the eSIM download and activation process. The portal provides instructions for completing the activation.
- **Common Use**: This method is beneficial for users who prefer managing their mobile plans through online portals.

Each activation method provides a different level of convenience and flexibility, catering to various user preferences and technological capabilities.
