Part 1. What Is eSIM Transfer

eSIM transfer refers to the process of moving an embedded SIM (eSIM) from one iPhone to another. Unlike traditional SIM cards that require physical swapping, eSIMs are digital and can be activated remotely. This capability allows users to switch devices without needing a new SIM card or visiting a carrier store.

The transfer process is designed to be straightforward: during the setup of a new iPhone, users can select the option to transfer their eSIM from their old device, typically through Bluetooth or Wi-Fi connections. The eSIM transfer feature is available on iPhone XS and later models.

Part 2. Why Does It Say Your SIM Is Not Supported eSIM Transfer

When attempting to transfer an eSIM from your old iPhone to a new one, you might encounter the message stating that "the SIM in your old phone doesn't support eSIM transfer". This issue can arise for several reasons, primarily related to carrier restrictions, device compatibility, and the specifics of your eSIM setup. Understanding these factors can help you troubleshoot the problem effectively.

Carrier Restrictions: Not all carriers support eSIM transfers between devices. If your carrier does not offer this feature, you will need to obtain a new eSIM or revert to using a physical SIM card.
Device Compatibility: The old and new iPhones must both support eSIM technology. If your old device is an earlier model that does not fully support eSIM functionality, it may lead to this error.
Outdated Software: Both devices should be running the latest version of iOS. Outdated software can create compatibility issues during the transfer process.
Activation Method: Some carriers require specific methods for activating or transferring eSIMs. If you attempt to use an unsupported method, you may receive this error message.
Account Issues: Problems with your cellular account, such as unpaid bills or restrictions on your plan, can prevent successful eSIM transfers.
Incorrect Settings: If the settings on either device are not configured correctly (e.g., Bluetooth or Wi-Fi is disabled), it can hinder the transfer process.
