Samsung Galaxy S25 eSIM

Does the Samsung Galaxy S25 support eSIM?

Samsung Galaxy S25 eSIM compatibility

Yes, the Samsung Galaxy S25 supports eSIM. All models in the Galaxy S25 series—including the S25, S25+, and S25 Ultra—ship with eSIM capability built in. This applies to devices sold globally, though you should verify with your carrier that they provision eSIM service in your region.

Dual SIM options on the Galaxy S25

The Samsung Galaxy S25 offers flexible dual-SIM functionality. You can run one physical nano-SIM alongside one eSIM, or configure two eSIMs simultaneously without using the physical tray at all. This makes the device ideal for travelers who want to keep their home number active while adding a local data plan. The phone can store multiple eSIM profiles—typically eight or more—but only two lines (in any combination of physical and eSIM) can be active at once.

How to set up an eSIM on the Samsung Galaxy S25

Activate your eSIM profile in Settings

Setting up an eSIM on your Samsung Galaxy S25 takes about a minute once you have your QR code or activation details from your carrier or travel-eSIM provider. Make sure you're connected to Wi-Fi before you begin.

Open Settings and tap Connections.
Tap SIM manager (or SIM card manager depending on your software version).
Select Add eSIM or Add mobile plan.
Choose Scan QR code and point your camera at the QR code provided by your carrier or eSIM vendor. Alternatively, tap Enter activation code manually if you received an SM-DP+ address and confirmation code.
Confirm the plan details and tap Add.
Label the new line—for example, "Travel" or "Work"—so you can easily identify it when switching between plans.
Choose which SIM to use for mobile data, calls, and messages in the SIM manager settings.

Select your default line for data and calls

After installation, the Galaxy S25 will prompt you to set a default line for mobile data. You can change this anytime in Settings → Connections → SIM manager. If you're using a travel eSIM for data and want to keep your home SIM active for calls and texts, designate the eSIM as your data line and the physical SIM for voice.

Using a travel eSIM on the Samsung Galaxy S25

Stay connected abroad without roaming fees

A travel eSIM is the easiest way to get mobile data when you fly internationally. Instead of paying your home carrier's roaming rates or hunting for a local SIM card at the airport, you install a data-only eSIM before you leave. Your home number stays active on your physical SIM (or a second eSIM), so you can still receive calls and texts for two-factor authentication.

Regional and country-specific plans typically activate the moment you land and connect to a local network. You can browse eSIM plans by destination, compare data allowances, and install the profile days or even weeks before departure. Once you're back home, simply switch your data line back to your primary SIM in the SIM manager.

Install your travel eSIM before your trip

Most travel-eSIM providers let you download and install the profile while you're still at home. The plan won't start until you arrive in the coverage country and toggle on the eSIM line. This means you can board your flight with everything ready—no scrambling in an unfamiliar airport, no language barriers, and no need to swap tiny SIM cards with a paperclip.

Tips & troubleshooting

Turn on data roaming for your eSIM line

Even though you're using a local or regional eSIM, Android sometimes requires data roaming to be enabled for the eSIM profile to connect. Go to Settings → Connections → Mobile networks, select your eSIM, and toggle Data roaming on. You won't incur roaming charges because the eSIM is already a local plan in the country you're visiting.

Keep your home SIM active for calls and authentication codes

If you're traveling, leave your home SIM or eSIM enabled but set the travel eSIM as your data line. This way, you'll receive SMS verification codes and phone calls on your regular number while browsing, mapping, and streaming on affordable local data. You can toggle between lines instantly in the SIM manager without restarting the phone.

What to do if the QR code won't scan

If your camera won't focus on the QR code, increase the screen brightness on the device displaying it or try scanning from a printed copy. You can also tap Enter activation code manually in the eSIM setup menu and type the SM-DP+ address and activation code provided by your carrier. If the profile still won't install, restart your Galaxy S25, confirm you have a stable Wi-Fi connection, and check that your device isn't carrier-locked. For persistent issues, eSIM setup help is available.

Check eSIM compatibility for other devices

If you're comparing phones or tablets, you can check another device's eSIM compatibility to see which models in your household support embedded SIM technology. Not all Android phones or Samsung models include eSIM, so it's worth confirming before you purchase a plan.

Galaxy S25 eSIM FAQ

Everything travellers ask about using an eSIM on the Galaxy S25.

Is Samsung S25 dual SIM?

Yes, the Samsung Galaxy S25 supports dual SIM. You can use one physical nano-SIM and one eSIM at the same time, or activate two eSIM profiles simultaneously. Only two lines can be active at once, but the phone stores multiple eSIM profiles so you can switch between them in Settings without reinstalling.

How many eSIMs can you have on a Samsung S25?

The Samsung Galaxy S25 can store eight or more eSIM profiles, though the exact number depends on software and carrier configurations. You can have two eSIMs active simultaneously—or one eSIM and one physical SIM—but you'll need to deactivate one profile if you want to enable a third.

What is the disadvantage of eSIM?

The main disadvantage is that you can't instantly move an eSIM to a new phone by swapping a physical card. If your device breaks, you'll need to contact your carrier to reissue the eSIM profile. Some carriers also charge a fee for eSIM redownloads, and a few budget or regional operators don't support eSIM provisioning at all.

Does Samsung have built in eSIM?

Yes, Samsung includes built-in eSIM support in its flagship Galaxy S series (S21 and newer in most markets), the Galaxy Z Fold and Z Flip foldables, and some A-series mid-range models. The Galaxy S25, S25+, and S25 Ultra all ship with eSIM capability worldwide, though carrier support varies by country and network.

Can I convert my physical SIM to eSIM on the Samsung Galaxy S25?

Many carriers let you convert an existing physical SIM to an eSIM by requesting a profile transfer through their app or customer service. Once approved, you'll receive a QR code to install the eSIM version of your current plan. Check with your carrier to confirm they offer SIM-to-eSIM conversion and whether any fees apply.
