How to Install an eSIM on Android: Step-by-Step Travel Guide

Installing a travel eSIM on Android is usually straightforward, but the exact steps can vary by phone brand. A Samsung Galaxy phone may use Connections and SIM Manager, while a Google Pixel may use Network & internet and SIMs. Other Android phones may use names like Mobile Network, Cellular Network, SIM Cards, or Add mobile plan.

This guide explains how to install an eSIM on Android before your trip, including Samsung Galaxy, Google Pixel, and general Android instructions. It also covers the important settings to check after installation, such as mobile data, data roaming, and your default SIM for calls and SMS.

Google’s Pixel support page explains that eSIM setup can be done during phone setup by choosing Download SIM, or later through Android settings. Reference: Google Pixel Help: Set up a new eSIM

Samsung’s official support page explains that Galaxy devices can add an eSIM through Settings > Connections > SIM manager > Add eSIM, with options such as simple setup, QR code scanning, or manual entry depending on device, country, and carrier.

Before you start

Before installing a travel eSIM on Android, make sure you have:

  • An eSIM-compatible Android phone
  • An unlocked phone
  • A stable Wi-Fi connection
  • Your eSIM QR code, activation link, or manual details
  • Your destination covered by the eSIM plan
  • Enough time to complete setup before departure

Why Android eSIM steps can look different

Android is used by many phone brands. This means the eSIM setup menu can look different depending on your phone model, Android version, region, and carrier.

For example:

  • Samsung may use Settings > Connections > SIM Manager
  • Google Pixel may use Settings > Network & internet > SIMs
  • Some phones may say Mobile Network
  • Some phones may say Cellular Network
  • Some phones may say Add mobile plan
  • Some phones may say Download SIM
  • Some phones may say Add eSIM

The idea is the same: you are adding a digital SIM profile to your phone. The menu names are the part that changes.

When should you install your Android eSIM?

For most travelers, the best time to install your eSIM is before departure, while you still have stable Wi-Fi.

A good routine is:

  1. Buy your travel eSIM before your trip.
  2. Install it at home, at your hotel, or using reliable airport Wi-Fi.
  3. Label the eSIM clearly.
  4. Keep your home SIM active if you need calls or SMS.
  5. Turn on the travel eSIM when you arrive.
  6. Set the travel eSIM as your mobile data SIM.
  7. Enable roaming for the travel eSIM if your plan requires it.

Important: Some eSIM plans start their validity after installation. Others start after the eSIM first connects to a supported network. Always check your plan details before installing.

Method 1: Install an eSIM on Samsung Galaxy

Samsung Galaxy phones are among the most common Android phones used by travelers. Exact wording may vary by model and One UI version, but the general steps are similar.

Samsung Galaxy QR code setup

  1. Connect your Samsung phone to Wi-Fi.
  2. Open Settings.
  3. Tap Connections.
  4. Tap SIM Manager.
  5. Tap Add eSIM.
  6. Choose Scan QR code if shown.
  7. Scan the QR code from your eSIM email or order page.
  8. Follow the on-screen instructions.
  9. Wait for the eSIM to install.
  10. Label the eSIM clearly, such as “Travel”, “Japan”, “Canada”, or “Arenoli”.
  11. Choose the correct SIM for mobile data.

Samsung’s official support page says Galaxy devices may support adding an eSIM through simple setup, QR code scanning, or manual entry, depending on device and carrier support. Reference: Samsung Canada: Galaxy eSIM and supported network carriers

Samsung Galaxy manual setup

If scanning the QR code does not work, your provider may give manual details.

These may include:

  • SM-DP+ Address
  • Activation Code
  • Confirmation Code, if required

General Samsung manual setup path:

  1. Open Settings.
  2. Tap Connections.
  3. Tap SIM Manager.
  4. Tap Add eSIM.
  5. Choose an option such as Enter activation code or Enter details manually if available.
  6. Enter the details exactly as provided.
  7. Follow the on-screen instructions.

Manual entry can be sensitive to small mistakes, so copy the information carefully.

Method 2: Install an eSIM on Google Pixel

Google Pixel phones usually use the Network & internet settings area for SIM management.

Google Pixel QR code setup

  1. Connect your Pixel to Wi-Fi.
  2. Open Settings.
  3. Tap Network & internet.
  4. Tap SIMs.
  5. Tap Add SIM.
  6. Choose Set up an eSIM or Download a new eSIM.
  7. Scan the QR code from your eSIM email or order page.
  8. Follow the on-screen instructions.
  9. Wait for the eSIM to install.
  10. Set the travel eSIM as your mobile data SIM if you are ready to use it.

Google’s Pixel Help page says users can set up an eSIM during onboarding by choosing Download SIM and following the on-screen instructions. Reference: Google Pixel Help: Set up a new eSIM

Google Pixel manual setup

If your QR code does not work, you may be able to enter the eSIM details manually.

General path:

  1. Open Settings.
  2. Tap Network & internet.
  3. Tap SIMs.
  4. Tap Add SIM.
  5. Choose the option to download or add an eSIM.
  6. Look for manual entry if available.
  7. Enter the SM-DP+ Address and Activation Code from your provider.
  8. Follow the on-screen instructions.

Google also explains that eSIM setup can depend on your carrier, and you may need carrier support if the SIM is not automatically detected. Reference: Google Pixel Help: Set up a new eSIM

Method 3: Install an eSIM on other Android phones

For other Android phones, the exact settings path varies. This includes brands such as Motorola, OnePlus, Oppo, Xiaomi, Sony, Honor, Nothing, and others.

Try one of these paths:

  • Settings > Network & internet > SIMs
  • Settings > Connections > SIM Manager
  • Settings > Mobile Network
  • Settings > Cellular Network
  • Settings > SIM cards
  • Settings > Mobile plan
  • Settings > Search > eSIM

Look for buttons or menu items such as:

  • Add eSIM
  • Add SIM
  • Download SIM
  • Download a new eSIM
  • Add mobile plan
  • Scan QR code
  • Use QR code
  • Enter details manually

If you cannot find any eSIM option, your phone may not support eSIM, or the option may be hidden because of your model, software version, region, or carrier.

If your QR code is on the same Android phone

If the QR code is in an email or webpage on the same phone, you may not be able to scan it directly with the same device camera.

You can try:

  • Open the QR code on a laptop or tablet
  • Open the QR code on another phone
  • Print the QR code
  • Use the provider’s activation link if available
  • Use manual installation details
  • Save the QR code before your trip

If you are traveling with someone else, you can display the QR code on their phone and scan it with yours.

What should you choose after installing the eSIM?

After installation, your Android phone may ask which SIM to use for mobile data, calls, and SMS. Choose carefully.

Mobile data SIM

For travel internet, choose your travel eSIM as the mobile data SIM.

This is the most important setting. If mobile data stays on your home SIM, your phone may use your home carrier’s roaming data instead of the travel eSIM.

Look for settings such as:

  • Preferred SIM for mobile data
  • Mobile data SIM
  • Data SIM
  • Primary SIM for data
  • Use this SIM for mobile data

Set this to your travel eSIM.

Calls and SMS SIM

If your travel eSIM is data-only, keep your home SIM as the default for calls and SMS.

A common setup is:

  • Home SIM: calls and SMS
  • Travel eSIM: mobile data

This lets you keep your normal phone number for bank codes, calls, SMS, WhatsApp, iMessage-style services where applicable, and account verification.

If you are not sure whether your travel eSIM includes calls or SMS, read: Does a travel eSIM work for calls and SMS?

Data roaming

Many travel eSIMs require roaming to be enabled on the eSIM line. This does not mean you are using your home carrier’s roaming data, as long as mobile data is set to the travel eSIM.

Recommended setup:

  • Travel eSIM roaming: on, if required by the plan
  • Home SIM data roaming: off, unless you intentionally want to use your home carrier roaming

Android wording varies. The setting may be called:

  • Roaming
  • Data roaming
  • Mobile data roaming
  • Roaming data

Make sure you apply the setting to the correct SIM line.

After landing: how to turn on your Android travel eSIM

After you arrive at your destination:

  1. Open Settings.
  2. Go to your SIM or mobile network settings.
  3. Make sure the travel eSIM is turned on.
  4. Set mobile data to the travel eSIM.
  5. Enable roaming for the travel eSIM if required.
  6. Keep home SIM data roaming off if you want to avoid home carrier roaming charges.
  7. Wait a few minutes for the phone to connect.
  8. Open a browser or map app to test your connection.

If your eSIM was installed before departure but kept off, this is when you turn it on.

How to test your Android eSIM connection

Before leaving the airport, test your connection.

Try:

  • Loading a website
  • Opening Google Maps
  • Sending a message
  • Opening email
  • Checking a hotel, train, or ride-share app

If it works, you are ready to go.

If it does not work, stay near airport Wi-Fi while troubleshooting.

Common Android eSIM mistakes

Mistake 1: Installing without Wi-Fi

You usually need internet access to download the eSIM profile. Install your eSIM on stable Wi-Fi.

Mistake 2: Choosing the wrong data SIM

If mobile data is still set to your home SIM, your travel eSIM may be installed but unused.

Mistake 3: Forgetting to enable roaming for the travel eSIM

Some travel eSIMs need roaming enabled on the eSIM line. If your eSIM installs but has no data, check this setting.

Mistake 4: Leaving home SIM data roaming on

If your home SIM data roaming is on, you may accidentally use your home carrier’s roaming data.

Mistake 5: Deleting the eSIM too early

Do not delete your eSIM during your trip unless support tells you to. Many eSIMs can only be installed once and may not be reusable after deletion.

Mistake 6: Assuming all Android phones use the same menu

Android settings vary by brand. If the guide says SIM Manager but your phone says SIMs or Mobile Network, look for the equivalent setting.

Troubleshooting: Android eSIM not working

If your Android eSIM is not working, try these steps.

1. Turn Airplane Mode on and off

Turn Airplane Mode on, wait 10 seconds, then turn it off. This can force the phone to reconnect to the mobile network.

2. Restart your phone

A restart can help your Android phone refresh SIM and network settings.

3. Check that the eSIM is turned on

Go to your SIM settings and confirm the travel eSIM is enabled.

4. Check mobile data selection

Make sure mobile data is assigned to the travel eSIM, not your home SIM.

5. Check data roaming

Enable roaming for the travel eSIM if your plan requires it.

6. Check APN settings

Some eSIM providers may give APN settings. If your provider gives APN details, enter them exactly.

APN settings may be under:

  • Settings > Network & internet > SIMs
  • Settings > Connections > Mobile networks
  • Settings > Access Point Names
  • Settings > Mobile Network > Access Point Names

The exact path depends on your phone.

7. Check network selection

Usually, automatic network selection is best. If your eSIM provider gives a specific network instruction, follow it.

8. Check plan coverage and validity

Make sure:

  • The plan covers your current country
  • The plan has started
  • The plan has not expired
  • You still have data remaining
  • Your phone is unlocked
  • Your phone supports eSIM

9. Do not delete the eSIM while troubleshooting

Deleting the eSIM may make the issue worse if the eSIM cannot be reinstalled. Try other steps first.

Can I use my normal SIM and travel eSIM together on Android?

Usually, yes, if your Android phone supports dual SIM.

A common setup is:

  • Home SIM: calls and SMS
  • Travel eSIM: mobile data

This is useful because you can keep your normal number active for bank codes, calls, SMS, and app accounts, while using the travel eSIM for data.

However, exact dual SIM behavior varies by phone model. Some phones can keep two lines active at once. Some can store multiple eSIMs but only activate one at a time.

Can I install more than one eSIM on Android?

Many Android phones can store more than one eSIM profile, but this depends on the model. Some phones can store multiple eSIMs but only use one or two SIM lines at a time.

If you travel often, you may be able to keep eSIMs for different destinations stored on your phone and activate the one you need.

Should I install the eSIM before or after arrival?

Usually before arrival is better, as long as your plan validity rules allow it.

Install before travel if:

  • You have stable Wi-Fi
  • You want to avoid airport setup stress
  • Your plan starts after first connection to a supported network
  • Your provider recommends pre-installation

Wait until arrival if:

  • Your plan starts immediately after installation
  • You are unsure about validity timing
  • Your provider specifically tells you to install after arrival

Always follow your eSIM provider’s instructions.

Final thoughts

Installing an eSIM on Android is usually simple, but the menu names can vary by brand. Samsung Galaxy, Google Pixel, and other Android phones may all use slightly different wording.

The key steps are:

  • Connect to Wi-Fi
  • Add the eSIM through SIM or network settings
