If you searched for "eSIM phones," you're probably about to buy a data plan for a trip and want to confirm, before spending a penny, that your phone supports it. Or perhaps someone mentioned it to you, and you're not quite sure what it is. Here, we explain it without jargon: which phones work with eSIMs, how to check on yours in less than a minute, and what to do if your device doesn't support it.
What is an eSIM and what does it have to do with your phone?
An eSIM is a data chip integrated into your phone's circuit board, not a card you insert. You activate it by scanning a QR code or installing a profile from your phone settings. Most phones manufactured since 2018 include it, but not all: it's a good idea to check before buying any plan.
The most common confusion is thinking that an eSIM is a physical object that will arrive by mail, like a traditional SIM you buy at the airport. That's not the case: it's software that already lives inside the phone, waiting for you to add a data profile. If you've never installed one and want to understand the full mechanics before proceeding, you can first read what an eSIM is and how it works.
What does determine whether you can use it is the phone's hardware: the manufacturer must have included that chip when it was made. No software, update, or configuration can add it later if it didn't come from the factory. That's why the first question before traveling isn't "which plan should I buy?", but "does my phone support it?".
Which phones have a virtual eSIM?
Compatibility depends on the brand, model, and, in some cases, even the country where the device was sold. As a general reference—manufacturers add and remove models with each generation, so treat this as a starting point and not a definitive list—this is how it's currently distributed:
| Brand | Usually includes eSIM since | What to confirm before assuming it has it |
|---|---|---|
| Apple (iPhone) | iPhone XS, XS Max, and XR onwards | Devices purchased in mainland China do not come with eSIM, even if the model name is the same as those sold in Mexico or Colombia |
| Samsung (Galaxy) | Galaxy S20, Note 20, and the Z Flip / Z Fold lines onwards | Some units sold under contract with a specific operator arrive with the eSIM factory-locked |
| Google (Pixel) | Pixel 3 onwards | "a" variants (the budget line) don't always include it; check the exact model number |
| Motorola | Foldable Razr and the Edge+ line | Most entry-level G models still don't have it |
| Other brands (Honor, Oppo, Huawei) | Only in some recent high-end models | Availability varies greatly by country of sale; always check the technical specifications of the specific model |
This information surprises many people: if your iPhone was purchased in mainland China, it doesn't matter if it's the same model circulating in Latin America—Apple sells it there without an eSIM, only with a dual physical slot, due to a local regulation. It's worth checking if the device was given to you as a gift or bought on a trip. For a more detailed and updated list, with more models by brand, you can check which phones are eSIM compatible.
Which phones are eSIM-compatible in Mexico, Colombia, and Argentina?
The good news is that most phones officially sold in Latin America—through Telcel, Claro, Movistar, Tigo, Entel, and similar providers—do include eSIM when the base model offers it. Hardware compatibility doesn't change based on the country where you bought the device, except for specific cases like China that we already mentioned.
Where you do need to pay attention is in two specific situations. First: phones purchased in installments with an operator, which sometimes come with the eSIM disabled until the device is unlocked. Second: entry-level models sold under the same commercial name in different markets, but with different hardware configurations to cut costs—the same name doesn't always mean the same chip inside.
Therefore, rather than memorizing a list of models, the most reliable way is to check it directly on your device, which is exactly what you'll see in the next section.
How do you know if your specific phone accepts eSIM?
There are three quick ways to confirm it, and you don't need to install anything to do so:
1. Check the settings: on iPhone, go to Settings > Cellular Data and look for the option "Add eSIM" or "Set Up eSIM". On Android, look for Settings > Connections > SIM card manager (the exact name varies slightly by brand). If the option doesn't appear anywhere, your phone doesn't support it.
2. Dial *#06# from the call keypad. Next to the device's IMEI, an EID (the unique eSIM identifier) should also appear. If you see an EID, the phone physically supports it, even if your operator hasn't activated it yet.
3. Find the exact model number of your phone (not the generic commercial name) on the manufacturer's official website. This number is usually in Settings > About Phone, or printed on the original box.
Before buying any eSIM for travel, confirm two things on your phone: that it accepts eSIM and that it is unlocked from your operator. If either of these is missing, no eSIM will work, regardless of the provider you choose.
A phone locked to an operator may have the eSIM chip and still reject profiles from other providers until it is unlocked. If you have doubts about whether yours is unlocked, ask the operator from whom you bought it directly: it's a process they resolve, not something that depends on the eSIM itself.
What is the cheapest phone that accepts eSIM?
We won't give you a figure in dollars or pesos, because it changes all the time and depends on the store, the country, and the current promotions at the time you compare. What we can explain is the trend: when eSIM first appeared, it was exclusive to the most expensive top-of-the-line models of each brand. With each new generation, manufacturers gradually included it in mid-range models as well, so today the "cheapest" phone with eSIM is usually not the newest on the market, but a mid-range model from one or two generations ago.
There's an important nuance: in some countries, the most economical version of the same phone line is sold without the eSIM chip to reduce costs, even if the global version of the same model does have it. Therefore, if you are deciding which phone to buy with the intention of using eSIM for travel, don't just go by the price or the model name: verify the technical specifications of the exact unit you are going to buy, using the three-step method we saw in the previous section, before paying.
What are the disadvantages of eSIM?
eSIM solves several travel problems, but it's not perfect. These are the real limitations you should know before relying on it:
You cannot physically move it between phones. With a physical SIM, if your phone breaks, you can remove the card and put it into another borrowed device in seconds. With an eSIM, this is not possible: the profile is linked to the hardware of a specific phone, and if that device fails, you need to generate a new profile on another compatible device.
You need internet to install it the first time. Scanning the QR or downloading the profile requires an active connection—Wi-Fi, data, or another network—so if you plan to install it upon arriving at a destination without available Wi-Fi, you might be unable to do so until you find a network. The simplest solution is to install it before traveling, using your home Wi-Fi.
Not all phones and not all operators support it equally. As we've seen, there are still models—especially entry-level ones—without the necessary chip. And unlike traditional roaming, which your local operator activates automatically, eSIM depends on you installing and activating the correct profile before you need it; if you want to compare both options in depth, you can check eSIM vs roaming: which is better depending on the trip.
If you already have an eSIM installed and are experiencing connection or activation problems, most cases have a quick solution—you can check the most common eSIM problems and how to solve them before assuming the phone is faulty.
eSIM vs physical SIM for travel: which is better?
Neither is "better" in absolute terms: it depends on your phone and how you travel. This table summarizes the most important differences to consider when deciding:
| Criterion | eSIM | Physical SIM |
|---|---|---|
| How it's activated | Scan a QR or install a profile, without moving from where you are | Must be bought in person or wait for delivery, and change the card physically |
| Risk of losing it | Not lost or damaged: it's part of the phone | Can be lost, bent, or damaged when changing it multiple times |
| Compatibility | Only recent phones with the chip included | Practically any phone with a SIM slot |
| Changing plans during the trip | Install another profile without opening the phone | You need to get another physical card at the destination |
| Use with your local line | Keep your physical SIM for calls and use the eSIM only for data | You need a phone with a dual physical slot, which is less common |
For most short trips abroad, eSIM wins in convenience because you can install it before you leave and arrive with data working as soon as you land. If your phone is not compatible, a physical SIM is still a valid alternative.

Real-world example: how an eSIM works on an international trip
To make it less abstract, let's look at a concrete case. Valentina lives in Guadalajara and is taking a twelve-day trip to Italy and Portugal. Her phone is a two-year-old model that, when checked with the three-step method, turns out to be eSIM compatible.
One week before traveling, from her home Wi-Fi, she buys a data plan for both countries and downloads the eSIM profile to her phone. She doesn't need to wait for any delivery: the entire installation process takes about a minute. The eSIM is saved on the phone, ready to use, but not yet consuming data.
Upon landing in Rome, she activates that data line from her phone's settings—without touching her physical Mexican SIM, which continues to receive her usual calls and messages—and she already has internet for the map, translator, and hotel reservations. Days later, she crosses into Lisbon by train: since the plan covers multiple destinations, she doesn't need to buy or install anything new when changing countries.
If something doesn't work—an error message, questions about how to activate the correct APN—she can write via WhatsApp or email and receive 24/7 support in her language, without having to find an open physical store in another country. And if the trip is postponed, there's no rush: she has 180 days from purchase to activate the eSIM, so buying it in advance is not a risk.
How do you install an eSIM on a compatible phone?
If you've already confirmed that your phone accepts eSIM, installing the profile is simpler than setting up a new email account. Generally, the process is this:
1. Connect to Wi-Fi. This is the step most people forget: you need active internet to download the profile, so do it before you leave on your trip, not when you arrive at your destination airport.
2. Scan the QR code you receive when buying the plan, or install the profile directly if your provider offers that option with a single tap from your phone.
3. Wait a few seconds while the phone validates the profile and installs the new line. You don't need to restart the device or do anything else.
4. Before traveling, go to the settings for that line and activate mobile data and data roaming for that specific eSIM, leaving your physical line for calls if you prefer.

Frequently Asked Questions
Do I need an unlocked phone to install an eSIM?
Yes. eSIM relies on the phone accepting profiles from other providers in addition to the original operator. If the device is still locked to an operator, it will likely reject the profile even if the eSIM chip is present. Ask your operator if your device is unlocked before purchasing a plan.
Can I use my eSIM and my physical SIM at the same time?
On most compatible phones, yes. You can leave your physical SIM active for calls and messages from your usual number, and use the eSIM only for mobile data at your destination. This is the most common setup for travelers.
What happens if my phone is not eSIM compatible?
There's no way to add the chip via software if the device didn't come with it from the factory. In that case, the alternative is a local physical SIM or a portable Wi-Fi modem for your destination.
Does the same eSIM work for several countries on the same trip?
It depends on the plan you purchase: some cover only one country, and others cover several destinations within the same region. PuraSIM offers plans for over 200 destinations, so if your itinerary crosses several countries, it's worth checking which plan covers all of them before buying.
Can I install the eSIM before traveling, without being connected to the internet at the destination?
Yes, and it's highly recommended: install the profile using your home Wi-Fi before you leave, and activate it only upon landing. This way, you avoid relying on finding available Wi-Fi at your destination airport.
What happens if I change phones after buying an eSIM?
Normally, the profile cannot be transferred from one device to another: it remains linked to the phone where it was installed. If you change phones, you will need to generate a new profile for the new device. If this happens to you, you can write via email or WhatsApp for assistance, with 24/7 support available.
How long do I have to activate the eSIM after purchasing it?
180 days from the purchase date. You can buy it in advance without pressure to install it immediately.
Do generic or "unlocked" phones sold in local markets accept eSIM?
It varies greatly. Some devices sold as economical versions of a known model have hardware cutbacks to lower costs, and this sometimes includes removing the eSIM chip even if the "official" version of the same model does have it. Check the exact model number using the three-step method before assuming compatibility.
Conclusion
If your phone is less than four or five years old and is not a cut-down version to reduce costs, it most likely does accept eSIM: confirm it in a minute by dialing *#06# or checking your mobile data settings, as we saw in the compatibility section. If the result is positive, you don't need to buy any accessories or change your phone for your next trip: just install a profile before leaving.
With 24/7 support in all languages by email and WhatsApp, activation in approximately one minute, and 180 days to activate it from the moment you purchase it, the eSIM eliminates the most inconvenient part of arriving in another country: searching for where to buy a local SIM card before being able to use the map. If you want a complete step-by-step guide before your first trip with an eSIM, check out the ultimate eSIM guide for travel, and once you have your destination clear, you can see the available plans for more than 200 countries in the international eSIM collection.
