In short: Yes, the eSIM for Samsung Galaxy A54 works, but only on the 5G model sold in Europe, the United States, and other markets; the Indian versions and the A54 4G do not include it. Dial *#06#: if you see an EID number, your phone has an eSIM and you can 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 travelers, 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 looking for a SIM store or paying roaming fees. But there are nuances. Not all A54s are the same, and it's good to know exactly what you have in your hand before buying a plan. In this guide, we clarify everything, step by step and without hype.
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 (reference SM-A546B), which is what most people in Spain buy, does include eSIM. The US version also does. In contrast, the Indian variant (SM-A546E) came without eSIM, and the A54 in its 4G configuration also does not have it. In Latin America, things are more irregular: some countries received units with eSIM and others did not, so there you have to check for sure.
This is not a Samsung whim. The availability of eSIM in the same model varies depending on local regulations, agreements with operators, and network certification in each region. That's why two phones that look identical on the outside can behave differently on the inside.
| Version / Market | Has eSIM? | Notes |
|---|---|---|
| Galaxy A54 5G Europe (SM-A546B) | Yes | Most common in Spain |
| Galaxy A54 5G U.S. | Yes | Compatible with travel eSIM |
| Galaxy A54 5G India (SM-A546E) | No | Model without eSIM from factory |
| Galaxy A54 5G LatAm (depending on country) | Variable | Check with *#06# |
| Galaxy A54 4G (no 5G) | No | The 4G variant does not have eSIM |
How to check in 5 seconds if your A54 has eSIM
No need to open boxes or look for the serial number. Open the phone app and dial *#06# on the dial pad. A window will appear 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 integrated eSIM. If no EID appears, your unit is one of those that do not include it, and you will have to use a physical SIM.
A second method: go to Settings, search for "eSIM" or "SIM card manager." If the system offers 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 so good 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 operator's or travel plan's data. The chip is the same; what changes is that you can load and delete lines without touching anything physical, all through software.
In a mid-range phone like the A54, the eSIM has a specific advantage for travelers: the phone retains its physical nano SIM slot and, in addition, allows an active eSIM. That is, it works as a Dual SIM. You can keep your Spanish number in the slot to receive calls and SMS as usual, and use the travel eSIM only for data. Without changing anything, without being left incommunicado, without roaming. You land with internet and that's it. If you are interested in this combination of two lines, see how to take advantage 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's data) and your plan's QR code. With PuraSIM, that QR code arrives via email right after purchase. Here are the steps:
- Go to Settings → Connections → SIM card manager.
- Tap Add eSIM or the + icon.
- Select Scan provider QR code.
- Point the camera at the PuraSIM QR (or paste the manual activation code if you prefer).
- Wait for the profile to download. It usually takes between 3 and 8 minutes depending on your connection.
- When finished, activate the line and, once at the destination, enable Data roaming for that eSIM.
That last point confuses many people. Activating roaming on a travel eSIM does not mean you will pay roaming charges: the plan already includes data for the destination country, and the roaming box only tells the phone that it can connect to the local network. Without it, the eSIM won't find coverage. If the term sounds strange to you, here's a clear explanation of what data roaming is. And if you prefer a generic guide to the process for any Samsung, check out how to activate an eSIM on Samsung Galaxy.
Before traveling or upon arrival?
Ideally, you should 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 depend on airport Wi-Fi just when you're in a hurry. Install it beforehand, leave the line added but without activating roaming, and as soon as you land, you'll only have to turn on the data switch. Installing the profile doesn't consume any of your plan: the gigabyte counter starts running when the line first connects to the destination network (or according to the conditions of each plan). You have more nuances in our general guide on how to install an eSIM.
What data plan to choose for your A54 depending on the trip
The A54 is a phone designed to last all day and consume content without draining the battery, so it handles data quite well. To calculate how much you need, think about your actual usage: maps, messaging, and social media consume little; video streaming and video calls, much more. This table gives you an indicative reference based on the type of trip.
| Type of trip | Intended use | Indicative data |
|---|---|---|
| Europe getaway 1 week | Maps, social media, some photos | 5–10 GB |
| LatAm vacation 2 weeks | Moderate use + photos | 10–15 GB |
| Remote work 1 month | Video calls, email, browsing | 20 GB or more |
| Short trip to U.S. | Light use, messaging | 3–5 GB |
Depending on your destination, choose a per-country or regional plan. To move around Europe, the Europe eSIM covers dozens of countries with the same profile, which is very convenient if you cross several borders. For a trip to the United States, the United States eSIM saves you from your operator's roaming. And if you are from outside and come to Spain, you have the Spain eSIM with national coverage. In any case, always choose according to the actual days and gigabytes you will spend; overestimating the plan is a waste of money.
eSIM versus your operator's roaming
Classic roaming from your Spanish operator can be convenient within the European Union (where "roaming like at home" applies), but outside the EU, rates skyrocket and can exceed several euros a day, sometimes with tiny consumption caps. A travel eSIM gives you a fixed price and a known amount of data in advance, without surprises on your bill. We break down the full comparison in eSIM versus roaming, but the practical rule is simple: within the EU, your tariff might work; outside it, eSIM almost always wins in predictability and price.
What almost no one tells you about eSIM on the A54
Here are the details that are not in the manual and that prevent most real problems.
- Buying an unlocked phone matters more than you think. An A54 purchased with a contract from a Spanish operator may come locked. Locking does not only 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 unlocking from your operator before your trip.
- The EID is not your phone number. Many people dial *#06#, see the EID, and think that's their number. No. 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 cannot recover it with the same QR: codes are usually for single use. Do not delete a travel eSIM until it is exhausted or until you are sure you no longer need it.
- You can store multiple profiles, but only one active. The A54 stores several installed eSIM profiles, although only one can be active at a time in addition to the physical SIM. It is perfect for having one for a country ready and switching to the next without reinstalling.
- The "5G" in the name does not guarantee 5G at the destination. The A54 is 5G compatible, yes, but having real 5G depends on the local operator in the country offering it in that band and area. In many destinations, 4G will be more than enough, which on this phone performs well for maps, streaming, and video calls.
Frequent problems and how to solve them
The A54's eSIM is reliable, but if something fails, it's usually due to one of these causes. Before writing to support, check the list.
- The eSIM option does not appear. This is almost always because your unit does not include it (Indian model, A54 4G, or some LatAm variants). Confirm with *#06# that there is an EID. If there is but the option doesn't appear, update One UI to the latest version.
- The QR code gives an error when downloading. Connect to a stable Wi-Fi, disable any VPN, and try again. A saturated network or an active VPN are common causes of profile download failures.
- Installed but no data. Go to Settings → Connections → Mobile networks and activate data roaming for the eSIM. Also make sure that the eSIM is selected as the mobile data line, not your Spanish SIM.
- It connects but is slow. Check that you are not using data with the physical SIM, restart the phone so that it re-negotiates the network, and if it persists, select the network manually in Mobile networks → Operators.
- Operator lock. If nothing works and you bought the phone with a contract, the device may be locked. Request unlocking from your operator.
Frequently asked questions
Is the Samsung Galaxy A54 compatible with eSIM in Spain?
Yes. The version sold in Spain is the European Galaxy A54 5G (SM-A546B), which includes 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 physical SIM at the same time?
Yes. The A54 has a slot for a physical nano SIM and an eSIM, and both can be active simultaneously. It is common to leave your Spanish number in 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 stores several installed eSIM profiles at once, although only one can be active simultaneously (in addition to the physical SIM). This is useful for having profiles for several countries ready and switching from one to another without reinstalling anything.
Is the A54 purchased with an operator contract locked for eSIM?
It may be. If you bought it with a contract from a Spanish operator, you may need to request unlocking before using third-party eSIMs. An unlocked phone does not have this limitation, so it is advisable to buy it unlocked if you are going to travel.
Will the A54 have 5G with the travel eSIM?
The A54 is compatible with 5G, but whether you have actual 5G depends on whether the local operator at the destination offers it in that area. In many countries, you will operate with 4G, which on this phone offers more than enough speed for maps, streaming, and video calls.
What One UI version 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 problems, update the system to the latest available version from Settings → Software update before trying again.
Can the same QR be reused if I delete the eSIM from the A54?
Generally not. Activation QR codes are usually for 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 it is exhausted or until you are sure you no longer need it.
