The shift from physical SIM cards to eSIM is one of the biggest changes happening in mobile technology. In 2025, most new Android smartphones now support automatic eSIM transfer, making it easier for users to switch devices without visiting a service center or handling tiny SIM trays.

This guide explains how eSIM transfer works on new Android phones, what carriers support it, common issues, and how you can troubleshoot activation problems. Everything is written in simple English and suitable for all Android users.

What Is eSIM?

eSIM (embedded SIM) is a digital SIM built into the motherboard of your device. Instead of inserting a physical card, your mobile plan is downloaded and activated electronically. This allows:

  • Faster activation

  • Better security

  • Ability to store multiple profiles

  • No risk of SIM damage or loss

Many Android brands—Samsung, Google Pixel, Xiaomi, Oppo, and Motorola—now support eSIM on most midrange and flagship models.

How eSIM Transfer Works in 2025

Android has added a standardized eSIM transfer system called Android eSIM Transfer Tool, allowing you to move your plan from an old device to a new one using:

  • QR codes

  • Google Account transfer

  • Carrier app authentication

  • Local device-to-device migration

Below is how each method works.

1. Transfer eSIM Using Google Account

Many 2024–2025 Android phones now allow eSIM migration through your Google account.

Steps

  1. Connect both phones to the internet.

  2. Log into the same Google account on the new phone.

  3. During setup, tap “Transfer SIM”.

  4. Approve the request on the old phone.

  5. Wait for activation to complete.

This option is very secure and works across brands.

2. Transfer eSIM Using QR Code

This method works if your carrier provides a QR code.

Steps

  1. Visit your carrier app or website to generate a QR eSIM code.

  2. On the new Android phone, go to:
    Settings → Network & Internet → SIMs → Add eSIM

  3. Scan the QR code.

  4. Wait for activation.

Many carriers worldwide support this method.

3. Transfer Using Carrier Apps

Some operators require you to log in to their official mobile app.

Examples include:

  • MTN

  • Airtel

  • AT&T

  • T-Mobile

  • Vodafone

Inside the app, you simply select “Move eSIM to another device” and follow the instructions.

4. Local Device-to-Device Transfer

This is the newest method introduced in late 2024.

Your new Android phone can detect your old phone wirelessly and move your mobile plan automatically.

Steps

  1. Place both phones near each other.

  2. Start setup on the new phone.

  3. Tap “Copy apps & data”.

  4. Select “Transfer eSIM” when prompted.

  5. Approve on the old phone.

This method is extremely fast and does not require internet.

Benefits of eSIM Transfer

Here are some advantages:

1. No More SIM Tools

You don’t need a SIM ejector or paperclip anymore.

2. Faster Device Switching

Upgrading phones becomes smoother, especially for creators, travelers, and technicians.

3. More Security

A stolen phone can’t have its SIM removed to avoid tracking.

4. Multiple Profiles

Some Android phones now support 8+ eSIM profiles, great for business users or international travel.

Troubleshooting eSIM Transfer Issues

If your eSIM won’t activate, try the tips below.

1. Ensure the Old Device Is Connected

Some carriers require the old device to stay online until transfer is approved.

2. Update Your Software

Android 14+ has better eSIM support.

3. Contact Your Carrier

Some network providers lock eSIM profiles for security reasons.

4. Reset Network Settings

Settings → System → Reset Options → Reset Wi-Fi, Mobile & Bluetooth

This fixes many activation errors.
