In short: most high-end Samsung Galaxy A phones launched since 2023 (A54, A55, A35, A25 and successors) support eSIM, although Samsung doesn't activate it uniformly across all regional variants. You can check in Settings → Connections → SIM card manager. Activation with PuraSim takes less than 5 minutes by scanning a QR code, no store or physical SIM needed.
If you have a Samsung Galaxy A and you're going on a trip, the first question is simple: does it have eSIM or not? The answer isn't a definitive yes or no for the entire series, because Samsung distributes eSIM support differently depending on the model and, especially, on the country where the phone was sold. Here's the complete guide: which models have it, how to check your specific unit, and how to activate a Samsung Galaxy A eSIM to travel with data from day one.
Which Samsung Galaxy A models have eSIM?
Samsung's A series is the manufacturer's mid-range, and that's the key: for years, Samsung reserved eSIM for its flagships (S, Z Fold, Z Flip, Note) and gradually brought it down to the A series, starting with the most powerful models in each generation. It's not like the S range, where almost every recent model includes eSIM without exception.
| Model | Does it have eSIM? | Notes |
|---|---|---|
| Galaxy A54 5G / A55 5G | Yes, in most European variants | Some units sold by carriers in certain markets arrive locked |
| Galaxy A34 5G / A35 5G | Yes, in most unlocked units | Check your specific unit before assuming it has it |
| Galaxy A25 5G / A26 5G | Yes, in newer versions | Entry-level models in the same range sometimes lack eSIM |
| Galaxy A14 / A15 / A16 (low-end) | No, in most cases | Entry-level models often omit eSIM due to component cost |
| Models prior to 2022 | Very uncommon | With specific exceptions, the A series did not have eSIM before that date |
Note the word "most": within the same model, Samsung manufactures different variants depending on the destination market, and some of these variants change the modem or directly remove the eSIM chip to reduce costs in countries where the operator prefers to continue selling only physical SIMs. That's why the commercial name of the phone isn't enough to know if yours has it: you need to look at the technical specifications of your exact unit or, better yet, check it directly on the phone itself, which is foolproof.
How to check if your Galaxy A has eSIM (in less than a minute)
Forget about searching for the model number on Google and comparing lists that become outdated every few months. The reliable method is to ask the phone directly:
- Open Settings
- Go to Connections
- Enter SIM card manager
- If you see the option Add mobile plan or Add eSIM, your Galaxy A is compatible
Be aware of a nuance in Samsung's interface (One UI): the menu is called "SIM card manager," not "Network & Internet" like on a Pixel with pure Android or "Mobile Data" like on an iPhone. If you follow another manufacturer's path, you won't find it and will think your phone isn't compatible when it actually is, it's just in a different place.
If your Galaxy A was purchased with a carrier contract (Movistar, Vodafone, Orange, or whatever in your country), it's possible that the hardware does have eSIM but the carrier has blocked it by software to force you to use only their SIM. In that case, the "Add eSIM" menu might not appear or might give an error when scanning a third-party QR. The solution is to ask the carrier to unlock the network, a process that in the European Union is free once the contractual commitment period ends.
If, after checking the menu, you still have doubts, in this eSIM installation guide you'll find the detailed process with screenshots for different manufacturers, useful if you have a mix of Android and iPhone devices at home.
How to activate eSIM on a Samsung Galaxy A step by step
Once you've confirmed that your model is compatible, activating a PuraSim eSIM on a Galaxy A is a five-minute process best done with the phone connected to Wi-Fi (the QR code can only be scanned once, so avoid doing it with unstable mobile data in case it fails midway):
- Buy your eSIM from PuraSim and you'll receive the QR code by email
- On your Galaxy A, go to Settings → Connections → SIM card manager
- Tap Add mobile plan and then Scan carrier QR code
- Point the camera at the PuraSim QR and wait for the system to download the profile
- Give the plan a recognizable name, for example "PuraSim Travel", so you don't confuse it with your usual line
- Under Preferred mobile data, select the PuraSim eSIM as your data line
- Activate Data roaming within the settings of that specific eSIM (it's a separate switch from your physical SIM, and is deactivated by default)
That last step is the one most people skip and the most common reason why someone lands and nothing works for them: activating the eSIM is not enough, you also have to activate its data roaming because, technically, you will still be "roaming" with respect to the network of the visited country even if it is the network that PuraSim has assigned you. If you've never tinkered with this, in this article about what data roaming is we explain it more calmly.
You can do this entire process before leaving home, with your phone on Wi-Fi: the profile remains installed and only truly activates when you land and the phone picks up the local network. There's no need to wait until you're at the destination airport or rely on airplane Wi-Fi.
Optimal Galaxy A setup for traveling with two active lines
Galaxy A phones use mid-range processors (Exynos or Snapdragon depending on the model and market), and keeping two lines active at once—your physical SIM and the PuraSim eSIM—demands more from the modem than using just one. In practice, this affects battery life, so it's a good idea to adjust settings from day one:
- Data line: In SIM card manager, set mobile data to the PuraSim eSIM. This way, all data consumption goes through it, and you avoid your Spanish carrier's roaming charges, which are usually very expensive or non-existent outside the EU.
- Calls and SMS: Leave them on your physical SIM to remain reachable on your usual number. However, receiving a call on your Spanish line from outside the EU may incur costs depending on your plan; check with your carrier before you leave.
- WhatsApp and messaging apps: These work via data, so as soon as the eSIM is active as the data line, everything will go through it without you having to do anything else.
- Automatic system and app updates: On a Galaxy A, it's advisable to disable them or force them to "Wi-Fi only" before traveling. A background One UI update can consume several GBs of your plan without warning.
- Battery saving with two active lines: If you notice your battery draining faster than usual, check that both SIMs aren't constantly searching for a network in weak coverage areas; this significantly increases consumption. You can temporarily disable the physical SIM if you only need data and don't expect calls that day.

What almost no one tells you about eSIM on a Galaxy A
Not all "A55s" in the world are the same phone internally. Samsung manufactures different hardware variants depending on the sales region, and this sometimes includes changing the modem or removing the eSIM chip in markets where less demand for that feature is anticipated. If you bought your Galaxy A outside the European Union, or second-hand without knowing its exact origin, don't assume what a generic spec sheet says is true: check your unit's menu.
Carrier lock is software, not hardware. A Galaxy A bought with a contract may have the eSIM chip physically installed and still not allow you to add a plan from another provider until the carrier unlocks it. Many people assume their phone "doesn't have eSIM" when in reality it has a software lock that can be resolved with a call.
Two active eSIMs at once consume more battery than you'd expect. It's not an internet myth: keeping the modem searching for and maintaining two networks simultaneously (your local SIM for calls and the PuraSim eSIM for data) has a real energy cost, more noticeable in the mid-range than in a flagship with a more efficient modem. Carrying a portable charger becomes non-optional on a long trip.
Factory reset deletes the eSIM, and there's no way to recover it without the carrier. If you sell your phone, format it, or take it to technical service and they perform a reset, the eSIM profile disappears just as if you had deleted it manually. Keep the email with the original PuraSim QR until your trip is over, in case you need to reinstall it.
For a weekend in a country bordering Spain, you probably don't need anything new. If your Spanish plan already includes roaming in the European Union (most current plans include it within the community block), buying an additional eSIM for a short trip to Portugal or France doesn't make much sense: use what you already pay for. Where it clearly pays off is outside the EU, where your Spanish operator's roaming costs skyrocket or simply don't exist.
Common mistakes when using eSIM on a Galaxy A
Scanning the QR before having Wi-Fi. The PuraSim code activates only once. If you scan it with poor coverage and the process cuts off midway, it may become unusable. Wait until you have stable Wi-Fi, even if it's your home Wi-Fi before traveling.
Leaving data roaming off on the new eSIM. We've mentioned this before, but it bears repeating because it's the most common cause of "I bought the eSIM and it's not working": each eSIM profile has its own roaming switch, independent of your physical SIM's.
Confusing which SIM is consuming data. If, after installing the eSIM, you still see consumption on your Spanish line, check that the preferred data line is actually on the PuraSim profile and hasn't defaulted to the physical SIM, which happens if you accept the automatic configuration without reviewing it.
Not naming the plan. If you have several eSIM profiles saved from previous trips, it's easy to accidentally activate one for a country you're no longer in. Rename each plan when installing it so you don't waste time figuring out which is which.
Trusting poorly managed airplane mode on the flight. Activate it for takeoff as required by regulations, but turn it off as soon as you land: the eSIM needs to register on the local network as soon as you touch down, and the sooner it does, the sooner you'll have data without having to restart your phone in the middle of the airport.
Frequently asked questions
How do I know if my specific Samsung Galaxy A has eSIM?
Go to Settings → Connections → SIM card manager. If you see the option "Add mobile plan" or "Add eSIM", your unit has it. This is more reliable than searching for the model name online, because Samsung sells different hardware variants depending on the country.
Do low-end Galaxy A models like the A14 or A15 have eSIM?
In most cases, no. Samsung reserves eSIM mainly for the mid-to-high-end models of the series (A5x, and in more recent generations also part of the A2x). Always check on the phone itself before buying an eSIM.
Can I use my PuraSim eSIM and my physical SIM from Spain simultaneously on the Galaxy A?
Yes, that's the beauty of dual SIM: you keep the physical SIM for calls and SMS from your usual number, and the PuraSim eSIM as your data line. This way, you remain reachable without paying data roaming charges from your Spanish operator.
What if my Galaxy A is locked by the carrier I bought it from?
The lock is usually software-based, not on the eSIM chip itself. Contact your carrier to request network unlocking; in the European Union, it's free once the contract period ends. Without that unlock, your phone might reject eSIM profiles from other providers.
Does the PuraSim eSIM work equally well on a Galaxy A as it does on an iPhone or a Samsung S series?
The eSIM profile itself is the same standard across all manufacturers. What changes is the interface for installing it and, in the case of the Galaxy A versus a flagship, battery consumption when maintaining two active lines might be slightly higher due to it being a mid-range modem.
Will the eSIM be deleted if I update One UI or the Galaxy A software?
A normal system update does not delete installed eSIM profiles. What does remove them is a complete factory reset. Keep the email with the original PuraSim QR in case you need to reinstall it after a reset.
Do I need a different eSIM for each country if I travel through several on the same trip?
It depends on the plan. If you're traveling through several countries in the European Union, a data eSIM for Europe covers your entire trip without changing profiles at each border. If your trip combines very different zones, compare your operator's roaming with a data eSIM to decide what's best for each leg of the journey.
PuraSim has data plans for over 200 destinations, with 24/7 support in all languages via email and WhatsApp in case anything doesn't go as expected.
