How to Transfer eSIM from One iPhone to Another: Complete Guide

How to Transfer eSIM from One iPhone to Another

Transferring your eSIM when migrating to a new iPhone can be seamless—if your carrier and software support it. In a busy world where you rely on cellular service immediately, knowing the right steps matters.

This detailed guide covers all methods: Quick Start, Bluetooth transfer, manual QR/activation code, carrier app transfer, and troubleshooting strategies to help avoid delays or disruptions.

1. Check Carrier Support, iOS Version & Requirements

Before attempting any transfer, confirm:

Your wireless carrier supports eSIM transfers—some smaller or regional carriers may not.
Both iPhones run iOS 16 or later, and Bluetooth is enabled.
Wi-Fi connection is stable to support QR code scanning or app-based activation.
Both devices can access Settings > Cellular (i.e., are unlocked and compatible with eSIM).

2. Quickest Route: Transfer eSIM During Setup (Quick Start)

If you're setting up a new iPhone:

Power on the new device and place it near your old iPhone.
Use Quick Start to prompt setup.
When asked to “Transfer From Nearby iPhone,” select the mobile number to transfer.
Confirm the transfer on the old iPhone and enter any verification codes shown.
Activation typically completes within minutes, and the eSIM on the old device is automatically deactivated.

This is the most streamlined method—as long as your carrier allows it.

3. Post-Setup or Manual Activation: QR Code or Carrier App

If Quick Start fails or your device is already set up:

Using a QR Code:
1. Ask your carrier for a valid eSIM QR code.
2. On the new iPhone, go to Settings > Cellular > Add Cellular Plan > Use QR Code.
3. Scan the code and follow on-screen prompts to activate.
Via Carrier App (e.g., Airtel, Jio):
1. Open the carrier's app on your new iPhone.
2. Select eSIM transfer options like “Upgrade to eSIM.”
3. Provide new phone EID via app and follow verification steps.
4. Wait for confirmation—activation may take up to a few hours.

This route ensures activation even if Quick Start is unavailable or unsupported.

4. Real-Life Insights from Users (Reddit)

Personal experiences often add valuable context:

"Jio supports Apple Quick Transfer within iOS 16+. Airtel required using their app and waiting ~2 hours before receiving a setup notification."

"With carriers like Visible, transfer requires entering an IMEI and safety code via their app, occasionally requiring multiple attempts."

These real-world examples highlight the variability depending on network provider.

5. Troubleshooting Tips: What to Do If Transfer Fails

If your eSIM won’t transfer:

Restart both iPhones and reconnect via Bluetooth.
Remove the eSIM plan from your old device then wait 5 minutes to 24 hours before attempting setup on your new iPhone.
Reset network settings: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
If still unsuccessful, contact your carrier for activation or QR code generation help.

These steps address common pitfalls such as app glitches, Bluetooth pairing issues, or carrier-side delays.

6. Verify Functionality

Once eSIM is transferred:

Go to Settings > Cellular and confirm the new eSIM line is active.
Make a test call or use mobile data to ensure it’s functional.
Wait to see if your old device receives any cellular access—proper transfer should deactivate it.
