Please note that eSIM cannot be directly transferred across devices. To use your eSIM on a new phone, follow these steps:
Step 1: Delete Existing eSIM Profile
Before setting up your eSIM on a new device, ensure both devices are connected to the internet/Wi-Fi. Delete the existing eSIM profile from your old device while connected to Wi-Fi. Wait for a few minutes for the deletion to be sent from device to eSIM server. Then, install eSIM on the new phone.
Step 2: Scan QR Code on New Device
Use the QR code provided in your order summary email to install the eSIM on your new phone.
- You can also access the Zero1 app and select the "SIM Activation" icon to retrieve your eSIM activation email. Alternatively, go to the eSIM retrieval page through this link: https://zero1.sg/activation/esim
Each QR code allows a maximum of 3 downloads.
If you exceed the limit, a replacement QR code will cost $5.45.
For eSIM replacement, the account holder must visit our Customer Service Centre in person with their original NRIC/Work Permit for verification. No appointment is required.
