eSIM for Samsung Galaxy S25: compatibility and activation in 2026

In brief: the Samsung Galaxy S25 supports eSIM on the S25, S25+, S25 Ultra and S25 Edge, with a few regional exceptions. Before buying a travel eSIM, check that your exact model is unlocked, updated and eSIM-ready. Then you can add a plan from Settings, scan a QR code, use a carrier app, or enter the activation details manually.

Does the Samsung Galaxy S25 support eSIM?

Yes. The Samsung Galaxy S25 range is compatible with eSIM across the main 2025 models: Galaxy S25, Galaxy S25+, Galaxy S25 Ultra and Galaxy S25 Edge. This makes it suitable for everyday dual SIM use, business travel and international data plans.

The key point is simple: eSIM support depends on both the phone model and the market where it was sold. A Galaxy S25 bought directly from Samsung or from an unlocked retailer is usually the safest option. A carrier-locked model may need to be unlocked before an eSIM profile can work properly.

Before you activate an eSIM on a Samsung S25

Before scanning a QR code, run three quick checks. They prevent most activation failures and help you avoid buying a plan that your phone cannot install.

• Check the eSIM menu: open Settings, then Connections, then SIM manager. If you see an option to add an eSIM, the phone is ready.
• Update the phone: install the latest One UI and Android updates before activation.
• Confirm that the phone is unlocked: a locked Galaxy S25 may reject another carrier’s eSIM profile.

How to activate eSIM on Samsung S25

The most common method is QR code activation. Your eSIM provider sends a QR code by email or shows it in your account. Keep the QR code visible on another screen, or print it if needed.

Activate with a QR code

• Connect your Galaxy S25 to Wi-Fi.
• Open Settings, then Connections.
• Tap SIM manager.
• Select Add eSIM.
• Choose the QR code option and scan the code from your provider.
• Wait for the profile to download, then name it clearly, for example “Travel data”.

Activate from a carrier app

Some providers let you install the eSIM directly from their app. This is convenient because the app can pass the activation details to Android without manually scanning anything.

Open the provider app, log in, select your plan and choose the eSIM installation option. When Android asks for confirmation, approve the new profile and wait until the S25 finishes downloading it.

Manual activation

Manual activation is less common, but it is useful when the QR code fails. Your provider must give you the SM-DP+ address and activation code. Enter them in the Galaxy S25 eSIM setup screen exactly as provided.

Which eSIM should you choose for a Galaxy S25?

The Galaxy S25 can work with many travel eSIM providers. The best choice depends on your destination, trip length, data needs and whether you want a simple one-country plan or a regional plan.

For a first travel setup, prioritise providers with clear activation instructions, reliable app support and easy plan management. MyBestSim’s current partner catalog includes providers such as Yesim, Jetpac, eSIM-On Shop, Ohayu, Simify and eSIM.dog, depending on the destination and availability.

Here are recommended eSIM providers to compare before your next trip.

You can also compare destination-specific plans from our eSIM comparison homepage. If your trip is already planned, search for your destination before installing anything on the phone.

How to use dual SIM on the Samsung S25 while travelling

Dual SIM is one of the strongest reasons to use eSIM on the Galaxy S25. You can keep your regular SIM for calls, banking texts and WhatsApp continuity, while using the eSIM for mobile data abroad.

Managing multiple eSIM profiles on the Galaxy S25

The Samsung S25 can store multiple eSIM profiles, which is useful if you travel often. You can keep an inactive plan for a country you visit regularly, then reactivate it later if the provider allows it.

Name each profile clearly. Use labels such as “UK data”, “Japan trip”, “Work line” or “Backup data”. Clear names make it easier to switch profiles quickly in SIM manager.

• For one trip: install the travel eSIM before departure, but activate data only when needed.
• For several countries: consider a regional or global eSIM if your itinerary crosses borders.
• For work: keep your business line separate from your personal number.

If you later upgrade to another Galaxy, read our guide on transferring an eSIM on a Galaxy device. Transfer rules can vary by carrier, so it is better to prepare before resetting the old phone.

Samsung S25 eSIM not working: quick fixes

If activation fails, do not delete the profile immediately. Most problems come from a weak connection, a locked phone, a used QR code or a mismatch between the plan and the device region.

• Restart the Galaxy S25 and try activation again on stable Wi-Fi.
• Check that the QR code has not already been used on another phone.
• Confirm that the device is unlocked for other carriers.
• Update One UI, then reopen SIM manager.
• Contact the eSIM provider if the profile downloads but never connects to a network.

Is eSIM better than a physical SIM on the Galaxy S25?

For most travellers, yes. eSIM is faster to install, easier to switch and safer to keep active because there is no physical card to lose. It is especially useful when you need data immediately after landing.

A physical SIM still has advantages in a few cases. Some local carriers only sell physical cards, and some users prefer a removable SIM for long-term plans. The best setup is often hybrid: keep your main physical SIM and add a travel eSIM for data.
