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

Transferring your phone number using an eSIM can be frustrating, especially when you’re faced with unclear errors like “eSIM transfer not supported”. Whether you use a physical SIM card or have already switched to eSIM, it’s important to understand how the process works differently across platforms. Below, we explore eSIM transfer challenges on both Android and iPhone.

eSIM (embedded SIM) is revolutionizing the way we use mobile data by replacing traditional SIM cards with a digital version. However, transferring your phone number to a new device using eSIM can come with challenges, whether you’re using an iPhone or an Android phone like a Samsung Galaxy.

Apple’s Quick Transfer feature allows users to move their eSIM during setup or later through the Settings app. However, not all carriers support this process. Users may face compatibility issues, especially if the phone was purchased in another region or if the account isn’t eligible. Messages like “unable to transfer phone number eSIM” or “eSIM transfer not supported” can indicate problems with the software version, profile configuration, or account status.

On Android devices, including popular Samsung Galaxy models, eSIM transfer procedures vary significantly. Some devices rely on QR code scanning, while others use carrier apps for activation. If your Android phone doesn’t support native eSIM transfer, manual configuration is required. Compatibility with your carrier, Android version, and device settings all play a role in the success of the eSIM migration. Android users may also face transfer interruptions due to outdated software, card conflicts, or locked devices.

eSIM transfer issues can affect both iPhone and Android users. Here are the most common causes:

On iPhone: Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings

On Android: Go to Settings > System > Reset > Reset Wi-Fi, Mobile & Bluetooth

Resetting network settings clears out old connections and cached data, which can fix eSIM setup issues on both platforms.

If you’re still facing problems like “can’t transfer eSIM” or “transfer from nearby iPhone not working”, it’s time to contact your carrier. They can check your account, resend a QR code, or manually activate the eSIM. If your phone was bought abroad, ask if the device is unlocked and fully compatible.

During phone setup, you might be prompted to transfer your eSIM. On iPhone, this is often automatic. On Android, particularly Samsung, you may need to manually scan a QR code or use a carrier app.

Whether on iOS or Android, updates fix bugs and improve eSIM support.

Ask them to reset your profile or reissue your QR code. If you need to buy a new plan, make sure the new one allows eSIM transfer.

iPhone users can use Quick Start. Android users may rely on apps or QR codes. Not all phones or carriers allow automatic transfer.

Whether you’re switching from a Galaxy to an iPhone, or just changing plans, encountering eSIM transfer not working errors is common. These issues usually stem from software, device compatibility, or carrier settings. With proper troubleshooting, most problems can be resolved quickly. Always check that your device, plan, and digital SIM card support eSIM before making a purchase.
