Transferring an eSIM between iPhones is a straightforward process for most users, yet it involves specific technical steps that require attention to detail. Whether you are upgrading to a new device or sharing a cellular plan with a family member, understanding the exact procedure ensures a seamless transition without service interruptions. This guide walks you through the necessary preparations, the transfer process itself, and troubleshooting tips for common issues.
Preparing Your Devices for Transfer
Before initiating the transfer, both the donor and recipient devices must meet specific criteria to ensure compatibility and security. The donor iPhone must no longer be linked to the cellular plan you intend to move, while the new iPhone needs to be ready for activation. Apple treats eSIM profiles as unique cryptographic keys, meaning a single plan cannot be active on two devices simultaneously.
Ensure both devices are updated to the latest version of iOS. Apple frequently releases software updates that patch security vulnerabilities and improve cellular connectivity. An outdated operating system may cause the transfer to fail or result in the eSIM not being recognized by the network.
Verify that your carrier supports eSIM transfers on your plan.
Back up both devices using iCloud or iTunes as a precaution.
Ensure the donor device has a strong internet connection during the process.
Initiating the Transfer via QR Code
The most common method to transfer eSIM involves generating a QR code from the donor device. This code contains the necessary cryptographic information to replicate the cellular plan on the new iPhone. You will typically access this option through the Settings menu under Cellular or Mobile Networks.
On the donor iPhone, navigate to Settings, tap on Cellular or Mobile Data, select the specific line you wish to transfer, and then choose "Remove Cellular Plan." Before confirming the removal, select "Transfer Carrier" and follow the prompts to display the QR code. Keep this screen active until the transfer is complete.
Activating the eSIM on the New iPhone
With the QR code displayed on the donor device, turn your attention to the new iPhone. Power on the device and complete the initial setup until you reach the Apps & Data screen. If you are restoring from a backup, ensure that process finishes before attempting to add the eSIM.
Go to Settings, tap on Cellular or Mobile Data, and select "Add Cellular Plan." Use the camera function to scan the QR code displayed on the donor phone. The iPhone will communicate with the carrier’s servers to validate the transfer. Once verified, the new plan will appear on the device, and you will be prompted to assign a label such as "Personal" or "Work."
Troubleshooting Common Issues
Even with careful preparation, some users encounter roadblocks during the transfer. The most frequent issue is a failure to scan the QR code, which usually points to network connectivity problems or incompatibility with the carrier. If the scan fails, verify that the new iPhone has cellular service and is connected to a stable Wi-Fi network.
