eSIM for Samsung Galaxy S25: compatibility and activation in 2026

Confirmed eSIM compatibility for all Galaxy S25 models

The Samsung Galaxy S25 natively integrates eSIM technology across its entire 2025 range. This official confirmation comes directly from Samsung Africa, which explicitly lists all compatible models: Galaxy S25, S25+, S25 Ultra, and S25 Edge.

eSIM compatibility thus extends to the entire series, marking a significant evolution compared to previous generations. Unlike older models where some regional variants were excluded, Samsung now standardizes this feature on its flagships.

Affected models and specifications

Here is a summary table of eSIM capabilities by model:

This storage capacity allows for particularly flexible eSIM profile management. You can keep multiple inactive mobile plans and reactivate them as needed, especially for international travel.

Important regional exceptions

Despite this widespread compatibility, some variants remain excluded. WonderConnect specifies that versions sold in China, Hong Kong, and Taiwan do not support eSIM due to local regulations.

Additionally, if your Samsung phone comes from a carrier with network lock, check its unlock status before any eSIM activation. Contract devices often require prior steps with the provider.

Technical requirements to activate the eSIM

Before proceeding with eSIM setup, several technical conditions must be met to ensure optimal operation.

Essential system checks

eSIM technology requires an up-to-date software environment. Your Galaxy S25 must run Android 15 or later, usually pre-installed on 2025 devices.

To check your Android version:
1. Go to Settings > About phone
2. Check the Software information section
3. Verify that the Android version is at least 15.0

Connectivity and unlocking

A stable internet connection (Wi-Fi or mobile data) is essential during activation. The mobile network must be accessible to download and authenticate the eSIM profile with the carrier.

Make sure your device is network unlocked. Galaxy S25 phones purchased directly from Samsung are generally unlocked, but those acquired through a carrier may require an unlocking procedure.

EID identification

The EID (Embedded Identity Document) is the unique identifier of your eSIM chip. To locate it on your Galaxy S25:

• Settings > About phone > Status > EID
• Or dial *#06# to display the IMEI and EID

Note this identifier, as some carriers require it when subscribing to an eSIM mobile plan.

Step-by-step configuration of your eSIM

The eSIM is mainly activated via two methods: QR code scanning or direct download from the carrier’s app. Ubigi confirms that all S25 models support both approaches.

Activation via QR code

This method remains the most universal way to set up your first eSIM:

• Obtain the QR code from your carrier (email, SMS, or web interface)
• On your Galaxy S25, go to Settings > Connections > SIM card manager
• Select Add mobile plan
• Choose Scan QR code
• Point the camera at the QR code
• Follow the on-screen activation instructions

Installation via carrier app

Many providers offer their own apps to simplify activation. This approach avoids handling QR codes and automates setup:

• Download your carrier’s official app
• Log in with your credentials
• Select the option “Add eSIM” or “New profile”
• Confirm installation on your device

Advanced manual configuration

For advanced users, manual entry of settings remains possible. You will need to provide:

• SM-DP+ server address (provided by the carrier)
• Unique activation code
• Confirmation code if required

This method is particularly suitable for corporate plans or specialized virtual operators.

Advanced management of multiple eSIM profiles

The advantages of the eSIM are fully revealed with simultaneous management of multiple profiles. Your Galaxy S25 can store up to 8 eSIM profiles, with 2 active in parallel alongside the physical SIM.

Switching between profiles

Changing the active profile is done without rebooting:

• Settings > Connections > SIM card manager
• Select the desired profile
• Activate/deactivate as needed
• Set preferences (data, calls, SMS)

This flexibility allows you to optimize costs depending on destinations or professional/personal use.

Assigning functions per SIM

Your Samsung phone allows assigning specific roles to each active SIM:

Optimization for travel

For international trips, set up an effective dual SIM strategy:

• Main SIM: keep your local plan to receive calls/SMS
• Travel eSIM: activate an international data plan to avoid roaming charges

Providers like Airalo or Saily offer eSIM plans specially designed for this nomadic use.

Disable mobile data on your main SIM before activating the travel eSIM to avoid unintended roaming fees.

Concrete benefits of the eSIM on Galaxy S25

eSIM technology transforms the mobile experience by bringing unmatched flexibility and convenience. On the Galaxy S25, these benefits materialize in daily use.

Instant activation

Unlike physical SIMs requiring delivery or store visits, the eSIM activates immediately. This responsiveness is crucial for:

• Business trips: connectivity upon landing
• Emergencies: backup plan in minutes
• Carrier testing: comparison without long-term commitment

Enhanced security

The absence of a physical card eliminates risks of loss, theft, or damage. eSIM profile management is done via secure authentication, reducing fraud by impersonation.

Moreover, remote deactivation protects your data in case of phone theft, a feature impossible with traditional SIMs.

Ecology and practicality

The eSIM helps reduce plastic waste related to SIM cards. This eco-friendly approach aligns with Samsung’s environmental commitments.

On the practical side, the absence of a SIM tray frees internal space to optimize the Galaxy S25’s waterproofing and battery capacity.

Pricing flexibility

The ease of switching carriers encourages competition and pricing innovation. You can:

• Test multiple providers without termination fees
• Negotiate better terms thanks to simplified mobility
• Combine specialized plans (data, international, professional)

This contractual freedom revolutionizes the traditional mobile plan by promoting modular and competitive offers.

Conclusion

The Samsung Galaxy S25 eSIM confirms the maturity of this technology across the entire 2025 range. With universal compatibility, storage for 8 profiles, and simplified activation, the Galaxy S25 positions itself as a benchmark for eSIM adoption.

This technological evolution fundamentally transforms our relationship with mobile connectivity, offering unprecedented flexibility for personal and professional uses. The future of the eSIM card looks promising with ongoing innovations in multi-profile management and IoT integration.
