How to activate eSIM on a Samsung smartphone in 2026

1. How to quickly check if your Samsung supports eSIM (models and prerequisites)

1.1 Compatible Samsung models — clear summary

Compatible Samsung models mainly include recent Galaxy ranges. The Galaxy S series from the S20+ onwards incorporate this technology, notably the S21, S22, S23, and S24 with their FE and Ultra variants depending on the market. Z Flip and Z Fold smartphones support eSIM from recent generations (Z Flip 3+ and Z Fold 3+).

Some mid-range models like the A54 and A55 also offer this feature. The Note20 remains compatible for certain regional variants. Galaxy Tab tablets S9 and S10 in 5G versions also include eSIM, unlike Wi-Fi-only versions.

The availability of Samsung eSIM strongly depends on the regional variant. Versions sold in France and the EU sometimes differ from American or Asian models. Always check the exact model before purchase.

This broad compatibility makes Samsung one of the most advanced manufacturers in this technology. However, as noted by Airalo in its complete guide, models A53 and below do not support eSIM.

1.2 Checks to perform on the device (Settings, EID, software version)

To confirm your device’s compatibility, several device checks are necessary. First, go to Settings > Connections > SIM card manager. If the option “Add eSIM” or “Add mobile plan” appears, your Samsung supports this technology.

An alternative method is to dial the code *#06# on your keypad. This code displays your device identifiers, including the EID (Embedded Identity Document) if eSIM is supported. The EID appears as a 32-digit code.

Samsung software version also plays a crucial role. Make sure your device has the latest update available via Settings > Software update. Recent versions of Android and One UI optimize eSIM management.

For a complete check, also consult the list of eSIM-compatible phones detailing other brands and models supporting this technology.

2. Complete guide to activating eSIM on Samsung (QR code, app, settings)

2.1 Activation by QR code (most common method)

eSIM activation via QR code remains the preferred method by most operators. Your provider sends you this code after subscription, usually by email or in your online customer area.

To proceed with activation, follow these steps:

• 1. Connect to Wi-Fi to ensure a stable connection
• 2. Go to Settings > Connections > SIM card manager
• 3. Select “Add mobile plan” or “Add eSIM”
• 4. Choose “Scan QR code”
• 5. Point the camera at the QR code provided by the operator
• 6. Follow the on-screen instructions to complete the installation

Keep the QR code accessible even after activation. It can be used to reinstall the eSIM in case of device reset or smartphone change.

This method works with most international eSIM providers like Airalo or Saily, especially popular for travel.

2.2 Installation via the operator’s app

Some operators offer the eSIM activation guide directly within their mobile app. This approach simplifies the process by automating several configuration steps.

French operators’ apps like Orange, SFR, Bouygues, or Free are progressively integrating this feature. Activation is then done in a few clicks from the dedicated interface, without handling a QR code.

Advantages of this method:

• Optimized user interface
• Centralized account and plan management
• Integrated technical support
• Automatic activation of network settings

2.3 Manual configuration (activation codes and network settings)

Manual configuration is necessary in some specific cases. This method uses activation codes provided by the operator instead of a QR code.

Go to Settings > Connections > SIM card manager > Add mobile plan > Enter information manually. Then enter the SM-DP+ server address, activation code, and confirmation ID provided by your operator.

This technical approach suits experienced users or when the QR code is unavailable. It ensures full control over connection settings.

3. French and European operators compatible with Samsung eSIM

3.1 French operators: Orange, SFR, Bouygues, Free

eSIM-compatible operators in France now cover the four main national networks. Orange was the pioneer by launching eSIM as early as 2018, followed by SFR, Bouygues Telecom, and more recently Free Mobile.

Each operator offers its own activation terms and pricing. Orange generally charges €10 for eSIM activation, while SFR includes it in some premium plans. Bouygues and Free adopt variable approaches depending on commercial offers.

The mobile coverage quality varies by operator and region. This directly influences the user experience with eSIM, especially on the move.

3.2 European and international operators

The European eSIM ecosystem is constantly expanding. Major German operators (Deutsche Telekom, Vodafone), British (EE, O2), and Spanish (Movistar, Vodafone) support this technology on compatible Samsung models.

For international travel, specialized providers like Ubigi or Maya offer multi-country plans particularly suited for Samsung users. These solutions avoid traditional roaming fees.

4. Practical uses and limitations of eSIM on Samsung devices

4.1 Dual SIM: combining eSIM and physical SIM

Uses and limitations of eSIM reveal their full potential with the Dual SIM function of recent Samsungs. This setup allows you to maintain both a professional and personal line simultaneously, or keep your French plan while adding a local eSIM when traveling.

The Samsung interface makes managing both lines easy. You can set which SIM to use by default for calls, SMS, and mobile data. Switching between lines is quick from settings or the notification bar.

Common usage scenarios:

• Main French line + temporary travel eSIM
• Professional plan + personal line
• Main operator + economical data plan
• National line + permanent international eSIM

4.2 Benefits for travelers and professionals

Travelers particularly appreciate the flexibility of Samsung eSIM. No more handling tiny SIM cards or searching for operator stores abroad. Activation is done remotely, often even before departure.

Professionals benefit from a clear separation between personal and business communications. This distinction facilitates expense management and preserves confidentiality depending on the context.

4.3 Technical and practical limitations

Despite its advantages, eSIM has some constraints. Transferring between devices remains more complex than with a physical SIM. Some operators limit the number of possible reactivations or charge for device changes.

Dependence on network for initial activation can be problematic in poorly covered areas. Also, not all plans are yet available in eSIM version, especially with virtual operators (MVNOs).

5. Troubleshooting and solutions for common Samsung eSIM issues

5.1 Activation problems and error codes

Activation difficulties are the most frequent issues with Samsung eSIM. The error “Unable to add mobile plan” often occurs due to connectivity problems or faulty QR codes.

Recommended solutions:

• Check Wi-Fi connection and restart the router if needed
• Ensure the QR code is not damaged or poorly lit
• Try activation in airplane mode, then reactivate connections
• Contact your operator to get a new activation code

5.2 Managing multiple eSIM profiles

Samsung allows storing multiple eSIM profiles, but only one remains active at a time (in addition to any physical SIM). Managing these profiles is done via Settings > Connections > SIM card manager.

To switch profiles, deactivate the current profile then activate the desired one. This usually takes a few seconds. Note: deleting an eSIM profile often requires a new paid activation from the operator.

5.3 Resetting and transferring eSIM

In case of major malfunction, network reset can resolve persistent issues. Go to Settings > General management > Reset > Reset network settings. This action deletes all eSIM profiles and requires full reactivation.

For transfer to a new Samsung, contact your operator beforehand. Some allow automatic transfer, others require new activation. Always keep original activation codes to facilitate these operations.

6. Conclusion

Samsung eSIM establishes itself as a mature and practical solution for users of recent Galaxy smartphones. The broad compatibility of the S, Z series and some A models, combined with easy activation, democratizes this technology. Whether to optimize your professional communications or simplify international travel, eSIM offers unmatched flexibility while retaining the possibility to use a traditional physical SIM simultaneously.
