What is an eSIM? How does eSIM works?

Activating an eSIM on your device has become increasingly streamlined, yet many users still find it challenging to navigate the initial setup. You will learn how to activate your eSIM across different devices and carriers.

Pre-activation checklist

Before beginning the eSIM activation process, ensure you have:

  • A device that supports eSIM technology
  • Active internet connection
  • Activation code or QR code
  • The device’s IMEI number is readily available
  • Backup of your current mobile data
  • The latest operating system installed

These preparations will help ensure a smooth activation process and minimize potential complications.

Initial device settings configuration

Most devices require specific settings to be enabled before eSIM activation. Navigate to your device’s settings menu and look for the “Cellular” or “Mobile Data” section. Here, you’ll typically find an option to “Add Cellular Plan” or “Add eSIM.” Ensure your device’s software is current, as outdated systems may not correctly support eSIM functionality.

QR code activation method

For eSIM activation, you typically scan a QR code provided by your carrier. To activate using this method:

  1. Access your device’s eSIM activation menu
  2. Select the “Scan QR Code” option
  3. Position your device’s camera over the QR code
  4. Follow the on-screen instructions
  5. Verify activation through test calls or data usage

Manual activation process

Manual activation provides an alternative method in cases where QR code scanning isn’t available or functional. This process typically involves:

  1. Locating your eSIM’s activation code
  2. Entering the code in your device’s settings
  3. Inputting additional carrier-specific information
  4. Confirming activation details
  5. Testing connectivity post-activation

Carrier-specific requirements

Different carriers may have unique requirements or steps for eSIM activation. Working with your eSIM provider requires attention to specific activation protocols and documentation. Some airlines might request additional verification steps or specific plan selection before activating.

Troubleshooting common issues

During activation, users might encounter various challenges. Common issues and their solutions include:
