How to Set Up an eSIM on Your Samsung Galaxy Phone

If you’re travelling abroad with a Samsung Galaxy phone, you may already have everything you need to avoid roaming charges built right into your device. Many current Galaxy models support eSIM, a digital SIM profile stored inside your phone. It lets you add a prepaid travel data plan before you fly, switch it on when you land, and keep your regular number running alongside it for the whole trip.

This guide covers which Galaxy models support eSIM, how to install and set up a travel eSIM step by step, Samsung’s newer eSIM features, and how to fix the most common problems.

Key Takeaways

• Samsung has supported eSIM since the Galaxy S20 series, and support now covers the S series, the Z Fold and Z Flip foldables, selected A series models, and several Galaxy Tabs.
• Your phone must be network-unlocked before a travel eSIM will install and work properly, so check this before you buy a plan.
• Installing a travel eSIM on a Samsung takes a few minutes using a QR code, with no shop visit or physical card needed.
• Travel eSIMs are usually data-only, so calls and texts keep running through your main SIM while the eSIM handles your data abroad.
• You’ll need to turn on data roaming for the eSIM, even on a plan built for your destination.

What Is an eSIM and How Does It Work on Samsung?

An eSIM, short for embedded SIM, is a small chip built into your phone rather than a removable plastic card. Because it lives inside the device, it can store network profiles and switch between them digitally, without any physical swapping. That makes a real difference when you travel, since you can load a travel data plan before your flight and have it ready to switch on the moment you land.

eSIMs are quickly becoming the norm. GSMA Intelligence predicted around 850 million eSIM smartphone connections globally by 2025, growing to 6.7 billion by 2030. That would account for 76% of all smartphone connections.

How an eSIM Differs From a Physical SIM

A traditional SIM card holds one carrier profile at a time. If you want data from a local network abroad, you have to remove your home SIM, insert a foreign one, and lose access to your regular number for the trip. With an eSIM, your home SIM can stay in place while a separate travel data plan handles your maps, messaging apps, and browsing.

Setup usually works through a QR code. Your travel eSIM provider emails you a code, you scan it in your phone’s settings, and the new profile downloads onto the embedded chip. There’s no shop visit, no physical card, and no queue at an airport kiosk.

Why This Matters for Samsung Users

Many Galaxy phones can run two lines side by side, so you can keep your main number active for two-factor authentication codes, banking alerts, and incoming calls while all your mobile data runs through a prepaid travel plan. That removes one of the most frustrating parts of travelling with a single physical SIM.

eSIM support varies by model and by the region where your phone was bought. Samsung notes that availability depends on your region, carrier, and device model, so it’s worth confirming your exact phone before you buy a plan.

Which Samsung Models Support eSIM?

Not every Samsung phone supports eSIM, so check your model early in your trip planning. The table below is based on Samsung’s eSIM support page.

Galaxy S Series

The Galaxy S series has offered eSIM from the S20 generation onward, so most Samsung flagship owners from the past several years are already covered. It’s the most consistently compatible line in Samsung’s range.

Galaxy Z Series

Samsung’s foldables have supported eSIM across multiple generations, from the latest Z Fold7 and Z Flip7 back through earlier models. That means you can keep your home SIM active for calls and texts while a travel eSIM handles your data abroad.

Galaxy A Series

eSIM in the Galaxy A range is limited to selected models, including the A56, A36, A55, A35, and A54. Samsung describes A series support as region-specific, so confirm your exact model and regional variant before assuming eSIM is available.

Galaxy Tab

Several Galaxy Tab models also support eSIM, including the Tab S11, S10, S9, and S8 series. That’s handy if you want mobile data on your tablet for navigation or streaming while you travel.

Check That Your Phone Is Unlocked

Whichever model you have, your device must be network-unlocked to use a travel eSIM. A phone locked to one carrier may block eSIM profiles from other providers, even if the hardware supports it. Breeze’s help centre explains a quick way to check on a Samsung:

1. Go to Settings and tap Connections.
2. Tap More connection settings near the bottom of the menu.
3. Tap Network unlock (on some regional models, this may be labelled as Network Lock Status or Sim Lock Status).
4. Check your status. If it reads "Device is unlocked", your phone can accept any travel eSIM. If it says "Locked", you must contact your network provider to request an unlock before you fly.

Breeze’s help centre also notes that a recently unlocked device may need some time before eSIM support kicks in.

How Do You Set Up an eSIM on a Samsung Phone?

Once you’ve confirmed your Galaxy is eSIM-compatible and unlocked, setup is quick. The steps below use the QR code method, which most travel eSIM providers use.

Before You Start

• Connect to Wi-Fi. Samsung advises connecting to Wi-Fi or mobile data before adding a plan, and a strong connection helps the download go smoothly.
• Have your QR code ready. Your code usually arrives in your order confirmation email, so open it on a second device or print it out.
• Set up before you fly. Installing at home on reliable Wi-Fi saves you scrambling for a connection at the airport.

Install Your eSIM With a QR Code

Breeze’s Samsung setup guide walks through these steps:

1. Open Settings and tap Connections.
2. Tap SIM manager.
3. Tap Add eSIM.
4. Choose Scan QR code from service provider.
5. Scan the QR code from your confirmation email.
6. Tap Add, then allow up to 10 minutes for activation.
7. Tap Done.

Breeze’s Samsung setup guide also warns not to close the window during installation, or the process will stop.

Menu names can vary slightly depending on your phone and software version. On some models, Samsung labels the path as Settings > Connections > SIM card manager > Add mobile plan > Add using QR code. If you can’t scan the code, you can usually enter the activation details manually instead.

Set Up Your SIMs for Travel

After the eSIM installs, tell your phone which SIM to use for what. Since travel eSIMs are usually data-only, the setup is simple:

1. Keep Calls and Messages on your original SIM.
2. In SIM manager, select the eSIM for Mobile data.
3. Go back to Connections, open Mobile networks, and turn on Data roaming.

That last step matters. Breeze’s data roaming guide says it’s essential that data roaming is enabled to use the eSIM. This keeps your regular number active for messages and security codes while the travel plan handles browsing, maps, and messaging apps. You can switch your data SIM back at any time in SIM manager.

What Are Samsung’s Newer eSIM Features?

Samsung has added several eSIM features to newer Galaxy phones, mainly aimed at making it easier to set up or move your main mobile plan. These don’t replace the QR code setup for most travel eSIMs, but they’re useful to know about.

• eSIM Simple Setup. Samsung explains that Simple Setup lets your carrier send an eSIM directly to your device, with no QR code needed. It’s available on the Galaxy S24, S25, and S26 series, the Z Fold and Z Flip series, and selected A models, with supported carriers.
• Transfer from another Galaxy or Android phone. The same Samsung page describes an eSIM Instant Transfer option under SIM Manager > Add eSIM. You enter a code to move your number from your old phone to your new one, as long as your carrier supports it.
• Transfer from an iPhone. Switching from Apple? Samsung lists a Transfer SIM from iPhone option, which works by scanning a QR code with the iPhone, with supported carriers.

For each of these, Samsung notes that your device must be unlocked, both phones need updated software, and Wi-Fi and Bluetooth must be switched on.

How Do You Fix Common Samsung eSIM Problems?

Even with a compatible phone and the right steps, a few issues come up regularly. Most have quick fixes once you know where to look.

eSIM Not Showing Up After Scanning the QR Code

If you scanned the code but no new plan appeared, the most likely causes are a weak internet connection or an interrupted download.

• Check your connection. Move to a stronger Wi-Fi network and try again.
• Give it time. Activation can take up to 10 minutes, so wait before assuming it’s failed.
• Restart and retry. Turn your phone off fully, switch it back on, and try the scan again.
• Contact your provider. Many eSIM QR codes can only be used once, so if a download failed partway, your provider’s support team can help.

eSIM Active but No Data Connection

This one’s confusing, because the plan looks installed but data won’t connect. A few settings checks usually fix it.

• Set the eSIM as your data SIM. Go to Settings > Connections > SIM manager and make sure the eSIM is selected for mobile data. Dual-SIM phones sometimes default back to your physical SIM.
• Turn on data roaming. Go to Settings > Connections > Mobile networks and switch on Data roaming. Breeze’s data roaming guide also suggests turning off data on your other SIM so the eSIM is used.
• Check whether you’ve arrived. Some plans only activate once you reach your destination, so if you’re still at home, it may simply be waiting for you to land.

eSIM Missing After You Removed It

If you delete an eSIM from your phone, you usually can’t bring it back yourself. Breeze’s uninstall guide recommends temporarily disabling an eSIM instead if you plan to use it again. If you’ve already removed it, contact your provider to see what options are available.

Error Saying the eSIM Is Locked or Unsupported

This almost always points to a network-locked phone. Phones bought from a carrier on a contract are often locked to that network, which blocks eSIMs from other providers. Contact your home carrier to request an unlock before you try again. Unlocking rules vary by country and carrier, so it’s worth asking even if you were told your phone is locked in the past.
