eSIM for Samsung Galaxy A54: is it compatible?

Bottom line: Yes, the eSIM for Samsung Galaxy A54 works, but only on the 5G model sold in Europe, the US, and other markets; the India version and the A54 4G don't include it. Dial *#06#: if you see an EID number, your phone has eSIM and you'll be able to travel with data without roaming.

The Samsung Galaxy A54 was one of the first mid-range phones to democratize a technology that until recently seemed reserved for flagships. And for anyone who travels, that changes things quite a bit: it means you can land in another country, activate a data plan in two minutes, and leave the airport connected without hunting for a SIM store or paying roaming fees. But there are nuances. Not all A54s are the same, and it's worth knowing exactly what you have in your hand before buying a plan. In this guide, we clear it all up, step by step and without the fluff.

Does the Samsung Galaxy A54 have eSIM?

The short answer is that it depends on the model and the market where it was sold. The European Galaxy A54 5G (model SM-A546B), which is what most people buy in Europe, does include eSIM. The US version does too. However, the India variant (SM-A546E) shipped without eSIM, and the A54 in its 4G configuration also doesn't have it. In Latin America, it's more hit-or-miss: some countries received units with eSIM and others didn't, so you absolutely have to check there.

This isn't a whim on Samsung's part. eSIM availability on the same model varies depending on local regulations, carrier agreements, and network certification for each region. That's why two phones that look identical on the outside can behave differently on the inside.

How to check in 5 seconds if your A54 has eSIM

No need to open boxes or hunt for the serial number. Open the phone app and dial *#06# on the keypad. A window will pop up with several device identifiers. If among them you see a field called EID (Embedded ID) with a long 32-digit number, congratulations: your phone has an embedded eSIM. If no EID appears, your unit is one of the ones that doesn't include it, and you'll have to stick with a physical SIM.

A second method: go into Settings, look for "eSIM" or "SIM card manager." If the system gives you the option to add an eSIM data plan, you have it. If that option doesn't exist anywhere, you don't have it. Before buying any plan, do this check. It's the fastest way to save yourself a headache.

What is an eSIM and why is it such a good fit for the A54?

An eSIM is a SIM soldered inside the phone that is programmed by software. Instead of inserting a physical card, you download a "profile" with your carrier or travel plan data. The chip is the same; what changes is that you can load and delete lines without touching anything physical — it's all done through software.

On a mid-range phone like the A54, eSIM has a specific advantage for travelers: the phone keeps its physical nano SIM slot and also supports one active eSIM. In other words, it works as Dual SIM. You can leave your local number in the slot to receive calls and SMS as usual, and use the travel eSIM just for data. Without changing anything, without losing contact, without roaming. You land with internet and you're set. If that two-line combo interests you, check out how to make the most of Dual SIM with eSIM and physical SIM.

How to Activate an eSIM on the Galaxy A54 Step by Step

The process in One UI is straightforward. You need a stable Wi-Fi connection (or your physical SIM data) and the QR code of your plan. With PuraSIM, that QR arrives by email right after purchase. Here are the steps:

1. Go to Settings → Connections → SIM card manager.
2. Tap Add eSIM or the + icon.
3. Select Scan provider QR code.
4. Point the camera at the PuraSIM QR code (or paste the manual activation code if you prefer).
5. Wait for the profile to download. It usually takes between 3 and 8 minutes depending on your connection.
6. When it finishes, activate the line and, once at your destination, enable Data roaming for that eSIM.

That last point confuses many people. Enabling roaming on a travel eSIM doesn't mean you'll pay roaming charges: the plan already includes data for the destination country, and the roaming toggle just tells your phone it can connect to the local network. Without it, the eSIM won't find coverage. If the term sounds unfamiliar, here's a clear explanation of what data roaming is. And if you prefer a generic guide for any Samsung, check out how to activate an eSIM on Samsung Galaxy.

Before Traveling or Upon Arrival?

The ideal approach is to install the profile at home, with good Wi-Fi, a few days before you leave. Downloading the profile requires internet, and you don't want to rely on airport Wi-Fi when you're in a hurry. Install it beforehand, leave the line added but with roaming off, and as soon as you land you'll only need to toggle data roaming on. Installing the profile doesn't use any of your plan: the gigabyte counter starts ticking when the line first connects to the destination network (or according to each plan's terms). There are more details in our general guide on how to install an eSIM.

Which Data Plan to Choose for Your A54 Based on Your Trip

The A54 is a phone designed to last all day and handle content without draining the battery, so it uses data pretty efficiently. To figure out how much you need, think about your actual usage: maps, messaging, and social networks use little data; video streaming and video calls use much more. This table gives you a rough reference based on the type of trip.

Depending on your destination, choose a country-specific plan or a regional one. For traveling around Europe, the Europe eSIM covers dozens of countries with a single profile, which is really handy if you're crossing multiple borders. For a trip to the United States, the United States eSIM saves you from your carrier's roaming charges. And if you're coming from abroad to Spain, you have the Spain eSIM with national coverage. In any case, always choose based on the days and actual gigabytes you'll use; overbuying a plan is just wasting money.

eSIM vs. Your Carrier's Roaming

The big question. Classic roaming from your carrier can be convenient inside the European Union (where "roam like at home" applies), but outside the EU, rates skyrocket and can exceed several euros per day, sometimes with very low data caps. A travel eSIM gives you a fixed price and a known amount of data upfront, with no bill shock. We break down the full comparison in eSIM vs. roaming, but the practical rule is simple: within the EU, your local plan might suffice; outside it, the eSIM almost always wins on predictability and price.

What almost nobody tells you about the eSIM on the A54

Here are the details that don't appear in the manual and that prevent most real-world problems.

• Buying an unlocked phone matters more than you think. An A54 bought with a contract from a carrier may come locked. The lock doesn't just affect physical SIMs: it can also prevent you from using third-party eSIMs. If you plan to travel and use external data plans, buy it unlocked or request the unlock from your carrier before your trip.
• The EID is not your phone number. Many people dial *#06#, see the EID, and think that's their number. It's not. The EID identifies the phone's eSIM chip; it's what some providers ask for to pre-install a profile. Save it, but don't confuse it with your line.
• Deleting an eSIM is permanent. If you delete an eSIM profile from the A54, in most cases you can't recover it with the same QR: codes are usually single-use. Don't delete a travel eSIM until you've used it up or you're sure you no longer need it.
• You can store multiple profiles, but only one active. The A54 keeps several installed eSIM profiles, though it can only have one active at a time alongside the physical SIM. It's perfect for having one country profile ready and switching to the next without reinstalling.
• The "5G" in the name doesn't guarantee 5G at your destination. The A54 is 5G compatible, yes, but whether you actually get 5G depends on the local carrier in that country offering it on that band and in that area. In many destinations you'll be fine with 4G, which on this phone handles maps, streaming, and video calls easily.

Common problems and how to fix them

The A54's eSIM is reliable, but if something goes wrong it's usually due to one of these causes. Before contacting support, go through the list.

• The eSIM option doesn't appear. This is almost always because your unit doesn't include it (Indian model, A54 4G, or some LatAm variants). Confirm with *#06# that there's an EID. If there is but the option doesn't show up, update One UI to the latest version.
• The QR gives an error when downloading. Connect to a stable Wi-Fi, disable any VPN, and try again. A congested network or an active VPN are common causes of profile download failures.
• Installed but no data. Go to Settings → Connections → Mobile networks and turn on data roaming for the eSIM. Also make sure the eSIM is selected as your mobile data line, not your local SIM.
• It connects but is slow. Check that you're not using up data on the physical SIM, restart the phone so it renegotiates the network, and if it continues, select the network manually in Mobile networks → Network operators.
• Carrier lock. If nothing works and you bought the phone with a contract, the device may be locked. Request the unlock from your carrier.

Frequently Asked Questions

Is the Samsung Galaxy A54 eSIM compatible in Spain?

Yes. The version sold in Spain is the European Galaxy A54 5G (SM-A546B), which comes with eSIM from the factory. You can confirm this by dialing *#06#: if an EID number appears, your phone has it and you can load travel data plans.

Can I use Dual SIM on the A54 with eSIM and a physical SIM at the same time?

Yes. The A54 has a slot for a physical nano SIM and eSIM, and both can be active simultaneously. The usual setup is to keep your local number on the physical SIM for calls and SMS, and use the PuraSIM eSIM only for data abroad.

How many eSIM profiles can the Galaxy A54 store?

The A54 can store several eSIM profiles installed at once, although only one can be active at a time (in addition to the physical SIM). This is useful for keeping profiles for multiple countries ready and switching between them without reinstalling anything.

Is the A54 bought with a carrier contract locked for eSIM?

It might be. If you bought it on a contract with a local carrier, you may need to request an unlock before using third-party eSIMs. An unlocked phone does not have this limitation, so buying it unlocked is recommended if you plan to travel.

Will the A54 have 5G with the travel eSIM?

The A54 is 5G compatible, but actual 5G availability depends on whether the local carrier offers it in that area. In many countries you will be on 4G, which on this phone provides plenty of speed for maps, streaming, and video calls.

Which version of One UI does the A54 need to use eSIM?

One UI 5.0 or higher is recommended. If you don't see the option to add an eSIM or have activation issues, update the system to the latest version from Settings → Software update before trying again.

Can I reuse the same QR if I delete the eSIM from the A54?

Generally no. Activation QR codes are usually single-use, so if you delete the profile you won't be able to reinstall it with the same QR. Do not delete a travel eSIM until you have used it up or you are sure you no longer need it.
