Does Samsung Galaxy S25 Support eSIM? Setup & Travel Guide (2026)

Does Samsung Galaxy S25 Support eSIM? Quick Answer Before You Start

Yes, Samsung Galaxy S25 models generally support eSIM. But do not assume every phone will work the same way. Your phone may support eSIM in general, but carrier or region restrictions can still apply. The fastest way to verify is to check for an EID and confirm that Add eSIM appears in Samsung's SIM settings.

All four Galaxy S25 variants support eSIM. The physical SIM tray differs by region, but the eSIM behaviour is the same across models.

Model	eSIM	US variant	International variant	China variant
Galaxy S25	Dual eSIM	1 nano-SIM + dual eSIM	2 nano-SIM + dual eSIM	2 nano-SIM, no eSIM
Galaxy S25+	Dual eSIM	1 nano-SIM + dual eSIM	2 nano-SIM + dual eSIM	2 nano-SIM, no eSIM
Galaxy S25 Edge	Dual eSIM	1 nano-SIM + dual eSIM	2 nano-SIM + dual eSIM	2 nano-SIM, no eSIM
Galaxy S25 Ultra	Dual eSIM	1 nano-SIM + dual eSIM	2 nano-SIM + dual eSIM	2 nano-SIM, no eSIM

All S25 models can run two eSIMs at the same time. That is useful for travel: keep your home line active for OTP texts while a travel data eSIM handles maps, rideshare, and translation apps. If you bought your phone in mainland China, the device ships without eSIM hardware and the steps below will not apply.

EID is the built-in ID number tied to your phone's eSIM capability. If your Galaxy S25 shows an EID, that is a strong sign the device supports eSIM.

You also need to check whether your phone is carrier unlocked. An unlocked phone can use plans from other providers. A locked phone may block eSIM setup from outside your original carrier.

Menu names can vary slightly depending on your One UI version or carrier. On most phones, the path is:

Settings > Connections > SIM manager > Add eSIM

How to Check eSIM Compatibility on Galaxy S25

Open the Phone app.
Dial *#06#.
Look for an EID number on the screen.
If you do not see it there, go to Settings > About phone > Status information.
Check whether an EID entry appears in that section.
If menu labels look slightly different, that can be normal on some carrier versions.

How to Check if Your Galaxy S25 Is Carrier Unlocked

Go to Settings > Connections > SIM manager and look for Add eSIM.
If your phone came from a major carrier, it may still be locked even if it supports eSIM.
If you are unsure, contact the original carrier and ask whether the device is unlocked.
If Add eSIM is missing, possible reasons include a carrier lock, software version, or regional rules.

⚠️ Important: eSIM only works on supported devices, and your phone should be unlocked. A carrier-locked device may block installation even if the Galaxy S25 model itself supports eSIM.

Before You Start: What You Need for a Smooth eSIM Setup

A lot of eSIM issues happen before installation even begins. The download itself needs stable internet, your activation details need to be ready, and low battery or outdated software can interrupt the setup halfway through.

Quick Setup Checklist

Connect to stable Wi-Fi
Make sure battery is above 30%
Keep your QR code or activation code ready
Confirm the phone is carrier unlocked
Install the latest software update in Settings > Software update
Keep your EID available if the provider asks for it

Save the QR code email before your flight. Screenshot or download the activation details, and if possible, install the eSIM while you still have reliable Wi-Fi at home or at the hotel. You can leave the line installed and only switch mobile data to it when the trip starts. This small step helps when airport Wi-Fi is weak or the QR email is buried in your inbox.

How to Install an eSIM on Samsung Galaxy S25

On the Galaxy S25, there are usually three ways to install an eSIM: QR code, manual activation, or through a provider app.

Installing by QR Code

Open Settings.
Tap Connections.
Tap SIM manager or SIMs.
Tap Add eSIM or Add mobile plan.
Choose Scan QR code.
Scan the QR code from your eSIM provider.
Confirm the installation when Samsung asks.
Wait 1 to 3 minutes while the eSIM profile downloads.
Name the line something clear like Japan eSIM or Travel Data.

Menu names can vary slightly depending on your One UI version or carrier.

Do not try to scan a QR code displayed on the same phone screen unless Samsung gives you another import option. It is usually easier to open the QR on a second device, print it, or use manual activation instead. If the download seems slow, give it a minute - some eSIM profiles take a little longer to finish installing, especially on weaker Wi-Fi.

Installing Manually with an Activation Code

Use this method if the QR code does not scan or your provider sent manual details instead.

Open Settings.
Tap Connections.
Tap SIM manager or SIMs.
Tap Add eSIM or Add mobile plan.
Choose the option to enter details manually.
Enter the SM-DP+ address.
Enter the activation code.
Enter a confirmation code if your provider gave you one.
Confirm and wait for the eSIM profile to download.

SM-DP+ is the server address your provider uses to deliver the eSIM profile. Double-check every character before submitting - manual entry usually fails because of one mistyped letter or symbol.

Installing Through a Provider App

Some providers let you install the eSIM directly through their app.

Download the provider app while connected to Wi-Fi.
Sign in and follow the prompts to add the mobile plan.
Approve the Samsung system message if it asks to add the eSIM.
Wait for the profile to install.

Not every provider offers app-based installation, so if you do not see that option, use QR or manual setup instead. As a general rule: start with QR, switch to manual activation if needed, and name the eSIM clearly so it is easy to manage later in SIM manager.

Best eSIM Settings for Travel on Galaxy S25 After Installation

Installing the eSIM is only half the job. You still need to tell the phone which line should handle data, and which line should handle calls and texts. This is where many travellers get stuck - the eSIM may be installed correctly, but the phone is still using the wrong SIM for mobile data.

Recommended Travel Setup

Setting	Recommended choice	Why it matters
Mobile data	Travel eSIM	Uses your travel plan for internet
Calls	Home SIM	Keeps your regular number active
Texts	Home SIM	Helps preserve your normal line
Data roaming on travel eSIM	On	Required by many travel eSIMs
Data roaming on home SIM	Off	Helps avoid roaming charges

A lot of travellers hesitate at the data roaming toggle because it sounds like something to avoid. But for many travel eSIM plans, turning data roaming on for the travel eSIM is exactly what makes mobile data work. Keep roaming off on your home SIM if you want to reduce the risk of extra carrier charges.

Can You Use eSIM and Physical SIM Together on Galaxy S25?

Yes, in most cases. One line can handle data while the other handles calls and texts. Actual behaviour may vary slightly by carrier, region, or software version, so check SIM manager on your specific phone.

Samsung Galaxy S25 eSIM Troubleshooting: Fix the Most Common Problems

If your Samsung Galaxy S25 eSIM setup is not working, the fix is usually one setting, not a major failure. Start with the simplest checks first.

QR Code Won't Scan

Clean the camera lens and try again.
Increase the screen brightness on the device showing the QR code.
Hold the phone steady and give the camera a second to focus.
Do not scan a QR code displayed on the same Galaxy S25 screen.
If scanning still fails, move to manual activation with the activation code.

eSIM Installed but No Internet

Go to Settings > Connections > SIM manager.
Make sure the eSIM is selected for Mobile data.
Turn on data roaming for the eSIM.
Restart the phone.
Turn Airplane mode on for 10 seconds, then turn it off.
Check APN settings if your provider requires them.

APN settings tell the phone how to connect to the provider's mobile data network. If you need to check them, the path is usually Settings > Connections > Mobile networks > Access Point Names. Only change APN details if your provider specifically gave you the correct values.

""Add eSIM"" Option Is Missing

Possible reasons include a carrier lock, a software update pending, or the menu appearing as SIMs instead of SIM manager. Region restrictions may also apply on some versions. Start by checking for updates in Settings > Software update, then look again under Connections. If the option is still missing and the phone came from a carrier, ask whether the device is unlocked for outside plans.

Weak or Unstable Connection

Temporarily switch network mode to LTE if 5G keeps dropping.
Move to an area with stronger coverage, especially outdoors.
Confirm the eSIM plan supports the country you are currently in.
Keep in mind that trains, underground stations, large buildings, and remote areas can affect signal.

Not every connection issue is caused by the phone itself. Local coverage, the partner network used by your travel eSIM, and your exact location all matter. If none of the above works, contact the eSIM provider and share screenshots of the error message or your settings screen.

Quick FAQ About eSIM on Samsung Galaxy S25

Do I Need to Turn On Data Roaming for My eSIM?

Usually, yes for travel eSIMs. Keep data roaming on for the travel eSIM if the provider requires it, and keep roaming off on your home SIM if you want to reduce extra charges.

Can I Keep My Regular Number for Calls and Texts?

Yes. If your home SIM stays active, you can usually keep using your normal number for calls and texts. Just remember your main carrier may still charge roaming fees.

Can I Transfer My eSIM to Another Phone Later?

This depends on the provider. Some allow transfer or reissue, while others require a new QR code or a new installation process. Not all eSIMs are easy to move between phones.

How Many eSIMs Can Galaxy S25 Store?

The Galaxy S25 can usually store multiple eSIM profiles, but the number of active lines at one time may vary by region or carrier. Check your SIM manager to see what your device supports.

Can I Delete and Reinstall the Same eSIM?

Sometimes, but this depends on the provider. Some eSIMs are single-use, while others can be reissued. Before deleting anything, make sure you can reinstall it if needed.

Does eSIM Work with a Physical SIM at the Same Time?

In most cases, yes. Many users run the travel eSIM for data and keep the physical home SIM for calls and texts. Exact dual-SIM behaviour can still vary slightly by carrier and region.

Choosing a Travel eSIM Plan for Your Trip

Once your phone is ready, the next step is choosing a plan that actually fits your trip. Focus on a few basics:

destination coverage
trip length
how much data you really use
whether the plan is data-only
whether hotspot is allowed
how clear the activation method is

If you are comparing options, BitJoy travel eSIM plans are organized by destination, duration, and data size, without overcomplicating the choice. The key is not just price. Make sure the setup instructions are clear and the plan works in the countries you will actually visit.

Ready to Travel

Getting eSIM set up on the Galaxy S25 comes down to a simple flow: check compatibility first, confirm your phone is unlocked, keep your QR or activation details ready, and install by QR code if possible. If QR setup fails, manual activation is the next best path. After that, set the travel eSIM as your mobile data line, turn on data roaming if required, and keep your home SIM active for calls or texts only if you are comfortable with possible carrier charges. Once these settings are in place, your Galaxy S25 should be travel-ready. Enjoy your trip.
