Unable to transfer phone number to eSIM? Here’s why and how to fix It

If you’re getting the error “unable to transfer phone number eSIM” while switching iPhones, you’re not alone. Many Apple users experience the dreaded message: “esim transfer not supported”. Whether it’s a new iPhone 15 Pro or an older iOS device, eSIM transfer issues are common. Sometimes, your device settings or account eligibility can prevent a successful migration. This can especially affect users trying to transfer from a nearby iPhone, as the iPhone eSIM transfer not working issue is increasingly reported.

Apple introduced eSIM Quick Transfer to simplify this process, but it still relies on several conditions: both devices must run recent versions of iOS, be close to each other, and the carrier must support the feature. If your iPhone can’t find your eSIM or says “Transfer Not Supported iPhone”, it may be due to missing updates, an unsupported SIM, or restrictions on your Apple account. Furthermore, it’s important to ensure your previous device is unlocked and not tied to another network or service contract.
