The release of the Samsung Galaxy S25 series has sparked questions about its connectivity features, specifically regarding eSIM technology. As mobile networks evolve, many users are moving away from traditional physical SIM cards in favor of digital solutions. However, confusion often remains about which specific models support it, how dual SIM works with US carriers, and the best ways to manage connectivity for international travel.
This guide provides a comprehensive breakdown of the Samsung Galaxy S25’s eSIM capabilities. We will cover compatibility across the entire lineup, step-by-step instructions for major US carriers, and how to leverage the device’s dual SIM features for both daily use and trips abroad with Orange Travel.
Does the Samsung Galaxy S25 support eSIM?
Yes, the Samsung Galaxy S25 series fully supports eSIM technology.
Samsung has integrated an embedded SIM (eSIM) directly into the hardware of the phone. This allows you to activate a cellular plan without needing to insert a physical plastic card. The device maintains a slot for a traditional nano-SIM, giving users the flexibility to use either option or both simultaneously. For many, the prepaid eSIM has become the preferred way to stay connected without the hassle of physical chips.
Samsung Galaxy S25 eSIM compatibility (S25, S25+, S25 Ultra)
All flagship models in the 2025 lineup are equipped with eSIM functionality. Below is the compatibility breakdown for the specific variations:
| Model | eSIM Support | Dual SIM Support |
| Samsung Galaxy S25 | Yes | Nano-SIM + eSIM |
| Samsung Galaxy S25+ | Yes | Nano-SIM + eSIM |
| Samsung Galaxy S25 Ultra | Yes | Nano-SIM + eSIM |
Is the Samsung Galaxy S25 dual SIM or dual eSIM?
The Samsung Galaxy S25 is designed as a Dual SIM device, but it is important to understand how this works in practice, especially for US models.
- Physical SIM + eSIM: You can have one active plan on the physical nano-SIM card and a second active plan on the eSIM. This is the most common “Dual SIM” setup.
- Multiple eSIM Profiles: You can store multiple eSIM profiles on the device. Unlike older models, the S25 supports Dual eSIM, meaning you can have two active eSIMs simultaneously, or use one eSIM alongside a physical SIM.
This flexibility allows you to keep your personal number active while adding a second line for business or data, without carrying two phones. If you are unsure if your hardware is ready, you can check if your phone is eSIM compatible.
How to activate eSIM on Samsung Galaxy S25
Setting up an eSIM on the Galaxy S25 is straightforward. Depending on your carrier, there are a few methods to get connected.
Activate eSIM with a carrier QR code
This is the standard method for most providers.
- Go to Settings > Connections > SIM Manager.
- Tap Add eSIM.
- Select Scan QR code and scan the code provided by your carrier.
- Follow the on-screen prompts to download and install the profile.
Convert physical SIM to eSIM
Some carriers allow you to convert your existing physical card to an eSIM directly within the phone settings, freeing up the physical slot. This is a great way to convert a physical SIM to eSIM on the fly.
- Navigate to Settings > Connections > SIM Manager.
- Select your physical SIM card.
- If supported, tap Convert to eSIM and follow the instructions.
Activate eSIM via carrier app
Major US carriers often prefer you use their official app.
- Download the carrier’s app (e.g., My Verizon, T-Mobile, myAT&T).
- Log in and find the “Activate Device” or “eSIM” section.
- Follow the app’s workflow, which will automatically push the eSIM profile to your S25.
US carriers that support eSIM on Samsung Galaxy S25
Most major US networks and many Mobile Virtual Network Operators (MVNOs) support eSIM on the Galaxy S25. Here is the current support status:
| Carrier | eSIM Support | Activation Method |
| AT&T | Yes | Carrier App / QR Code |
| T-Mobile | Yes | Carrier App / QR Code |
| Verizon | Yes | Carrier App / QR Code |
| Mint Mobile | Yes | App |
| Visible | Yes | App |
While US carriers work well for domestic coverage, many Samsung Galaxy S25 users choose a separate travel eSIM when traveling abroad to avoid expensive roaming charges.
Using eSIM on Samsung Galaxy S25 for international travel
Traveling internationally with a US carrier plan can often lead to “bill shock.” Traditional roaming fees from major providers like Verizon or AT&T can exceed $10 per day, accumulating quickly over a two-week trip. Furthermore, finding a local physical SIM card upon arrival involves waiting in lines at the airport and swapping out your primary SIM, which risks losing it.
The Samsung Galaxy S25’s Dual SIM capability solves this. By using a dedicated travel eSIM for data, you can keep your US number active for receiving two-factor authentication (OTP) texts or emergency calls, while routing all expensive data usage through a much cheaper, prepaid travel plan.
For instance, if you are traveling to France, you can activate a local profile instantly. Similarly, those planning a trip to Japan or exploring destinations in Mexico can avoid the high costs of international data.
Best travel eSIM option for Samsung Galaxy S25 users
For Samsung Galaxy S25 users who travel internationally, services like Orange Travel are often used as a secondary eSIM for data abroad. Unlike domestic carriers that charge high daily fees, Orange Travel offers prepaid data plans specifically designed for travelers.
Orange Travel provides several advantages for S25 owners:
- Global Coverage: Access to high-speed data in over 200 destinations.
- Reliability: As a major global telecom operator, Orange provides direct network quality, not just resold bandwidth.
- Flexibility: Plans range from country-specific bundles to all-inclusive regional (Europe, Asia) or global passes.

Why Samsung Galaxy S25 pairs well with Orange Travel eSIM

Upon arrival, your phone simply switches data to the Orange profile. You get full 5G/4G speeds and can use the S25’s Mobile Hotspot feature to share that connection with your laptop or travel companions without restriction.
