How to Transfer Physical SIM to eSIM

Switching from a physical SIM to an eSIM is straightforward but requires a compatible device and a mobile provider that supports eSIM activation. Follow these steps to make the transition seamless.

Step 1: Check If Your Phone Supports eSIM

Before transferring, make sure your phone supports eSIM. Most modern smartphones, including iPhones (XR and newer), Samsung Galaxy (S20 and newer), and Google Pixel (3 and newer), come with eSIM functionality.

Step 2: Request an eSIM from Your Carrier

If your current carrier supports eSIM, request a physical SIM to eSIM transfer. This can typically be done through:

 The carrier’s website
 Their official mobile app
 A visit to a retail store

Your carrier will provide a QR code or an activation code for the eSIM setup.

Step 3: Activate Your eSIM

For iPhone Users:

1. Go to Settings > Cellular > Add Cellular Plan

2. Scan the QR code provided by your carrier

3. Follow the on-screen instructions to activate
