How to activate your Airalo eSIM step-by-step
To activate your Airalo eSIM, open the app, go to "My eSIMs," choose the package, and follow the QR, manual, or direct installation method from your phone's Settings. You need stable Wi-Fi and an eSIM-compatible, unlocked phone; the process takes only a few minutes.
This guide was written by PuraSIM, which is another eSIM store for travelers. We do not sell Airalo packages or have access to their system, so everything stated in this note about Airalo comes directly from their own Help Center and official website, as of the date we consulted it: August 10, 2026. If Airalo updates its instructions after that date, this guide may become outdated in some minor detail; the general steps, however, have been stable for some time.
First things first: installation is always done from the Airalo app (to get the QR code or manual data) and from your phone's Settings (to install it). Airalo does not install anything for you remotely; you complete the process on your device. If you've never installed an eSIM, it's best to first understand what an eSIM is and how it differs from a physical card, because many common errors come from treating it as if it were the same thing.
What you need before you start
Before installing the Airalo eSIM, you need three things: an eSIM-compatible phone unlocked by the manufacturer (not tied to a carrier), a stable Wi-Fi connection during installation, and having already purchased the package within the Airalo app or website. Without all three, the process will get stuck at some point.
Compatibility is the step most people skip. Not all phones — not even all "premium" models — have eSIM enabled, and a carrier-unlocked phone is not the same as a phone with the eSIM function active in the SIM tray. Before buying any package, it's a good idea to check the list of eSIM-compatible phones so you don't end up with a paid package that your device can't use.
Regarding Wi-Fi: the eSIM profile is downloaded to your phone at the time of installation, so the connection is not a minor detail.
Installing an eSIM means downloading a profile to your phone. If the connection is cut off halfway through the download, the profile will be incomplete and you'll have to start over. That's why it's best to do it with stable Wi-Fi and without rushing.
In practice, this means it's not a good idea to try to install the eSIM already at the destination airport, connected to an unstable public Wi-Fi with dozens of people nearby. It's better to do it at home, calmly, before leaving on your trip.
The 3 ways to install an Airalo eSIM
According to Airalo's own Help Center, there are three available installation methods, and not all phones offer all three: QR code, manual installation (with SM-DP+ address and activation code), and direct installation from the app in a single step, available on newer devices and operating systems.
| Method | What it needs | When to use it |
|---|---|---|
| Direct installation | Airalo app open + phone compatible with this feature | This is the fastest method when available; a few taps and you're done |
| QR code | Stable Wi-Fi + scan the QR from Settings > Mobile Data | The most common method; works on the vast majority of eSIM phones |
| Manual (SM-DP+) | Copy the SM-DP+ address and activation code by hand | When the QR fails, the camera doesn't read it well, or the phone doesn't support direct scanning |
All three methods lead to the same result: a new data line installed alongside your physical SIM. The difference is in how many manual steps you have to take. If this is your first eSIM in general (not just Airalo's), you might want to check the general guide on how to install an eSIM first, because Android and iOS settings aren't named exactly the same, and that confuses a lot of people on their first attempt.
How to activate an Airalo eSIM without a QR code
If the QR code doesn't work for you — because your phone doesn't have a dual camera to scan it properly, because you've already used it once, or because you simply prefer to copy and paste — Airalo offers manual installation. Within the app, in "My eSIMs," tap the package, then "View instructions" and choose "Manual" as the method.
Two pieces of data will appear that you need to copy exactly as they are, without extra spaces: the SM-DP+ address and the activation code. They are pasted into Settings > Mobile Data > Add eSIM > Enter details manually, in the corresponding fields. If the app also asks for a confirmation code, that is also copied from there. After pasting the data, the phone asks to continue twice and waits a few minutes while the line is activated.
A common mistake with this method: copying the SM-DP+ address with leading or trailing spaces, which sometimes slip in when copying from the app. If the system says it cannot validate the address, check for this before assuming the package is corrupted.
How long Airalo eSIM activation takes
Activation takes a few minutes after completing the installation. On the official Airalo pages we reviewed on August 10, 2026, we did not find a guaranteed exact time, so the honest thing to say is precisely that: it takes a few minutes, and it mainly depends on the Wi-Fi remaining stable during the profile download.
The important thing during that wait is not to exit the installation screen or turn off the phone, because the process may be incomplete and force you to reinstall the profile from scratch. If a long time passes without a sign that the line is active, the quickest solution is usually to restart the phone once the installation is complete (not before) and check that the line appears enabled for data in Settings.
One point that almost no one checks: installing the eSIM is not the same as starting to consume data with it. You can install it in advance and leave it "dormant" until the day of your trip; what changes is when the validity period of the package starts counting, which is different for each eSIM. We talk about that in the next section.
Why your Airalo eSIM isn't working
When an Airalo eSIM "isn't working," it's almost never a broken package: in most cases, the line is installed but not configured as the active data line, or data roaming is turned off for that particular line. Before contacting support, it's worth checking your phone's settings.
| What you see | Most likely cause | What to check |
|---|---|---|
| No data upon arrival at destination | The eSIM is installed but not selected as the data line | Settings > Mobile Data > choose the Airalo line as primary for data |
| There's a signal but no browsing | Data roaming is turned off for that line | Activate "Data Roaming" specifically for the eSIM line, not just the physical one |
| "Could not add eSIM" when scanning QR | Unstable Wi-Fi during scanning, or QR has already been used once | Retry with another Wi-Fi network or switch to the manual method |
| Package appears "expired" without having been used | The activation policy for that specific package counts from installation, not from first use | Check the package's activation policy before installing it in advance |
If you've already checked these four points and it still doesn't work, then it's worth writing to support instead of continuing to try changes on your own; in the section on common eSIM problems, we review other symptoms that are not exclusive to Airalo, but to any eSIM, including ours.
When your Airalo package validity starts
This is probably the point that most confuses those who install the eSIM before traveling. According to Airalo's own Help Center, the package's validity starts counting when the eSIM connects to the destination network in most cases, but for some packages, it starts directly upon installation, regardless of your location. Which of the two rules applies depends on the "activation policy" of each specific package, and Airalo recommends checking it before purchasing, in the "Additional Information" section of each product.
The practical consequence: if you install the eSIM a week before traveling "to avoid rushing at the airport," in some packages, this can start consuming the days of validity even if you haven't used a single megabyte yet. This is not a system failure; it's a package condition that is often overlooked. It's worth comparing this to how a physical SIM works versus an eSIM, because with a physical SIM, the starting point of validity is usually much more intuitive: it begins when you insert and use it, not before.
Airalo's actual support channels
If, after checking the settings, your eSIM still doesn't work, Airalo offers support through three channels documented on its official help and contact pages: in-app chat, WhatsApp, and email. On the official Airalo pages we consulted, we did not find a telephone support number listed as a support channel; if one exists, it is not on the help or contact pages we reviewed on August 10, 2026.
This is relevant because it's a point where it's good to compare without exaggeration: neither Airalo nor PuraSIM offer phone support, which is common for this type of digital service. Both companies resolve issues via chat, WhatsApp, and email. The real difference between eSIM providers is almost never in the channel, but in how long it takes someone to respond there — and that's not something we can verifiably measure about a competitor from the outside, so we won't invent a number.
Airalo vs. PuraSIM: an objective comparison
With all the previous information now on the table, here is a direct comparison between both services on points that can be verified with source and date, without delving into prices (which change all the time and we will not quote without verifying them at the exact time of purchase).
| Criterion | Airalo | PuraSIM |
|---|---|---|
| Installation methods | QR, manual, and direct installation (according to their Help Center) | QR and manual, with activation in approximately 1 minute |
| Support channels | In-app chat, WhatsApp, and email, according to their official help and contact pages | Email and WhatsApp, 24/7 in all languages |
| Window for activation after purchase | Varies according to the activation policy of each package (to be checked before purchase) | 180 days from the date of purchase |
| Destination coverage | More than 200 countries and regions, according to their official website (consulted on August 10, 2026) | More than 200 destinations |
| Phone support | Not listed on their help or contact pages | Does not offer phone support |
In terms of coverage and support channels, both are practically on par according to what each officially publishes. The most concrete and verifiable difference is in the activation window: Airalo leaves it to the discretion of each individual package (you have to check it before buying, package by package), while PuraSIM applies a single period of 180 days for its entire international eSIM line, without needing to read different fine print for each product.
When Airalo is convenient and when it's worth comparing
Airalo states on its official website that it covers more than 200 countries and regions, so its catalog is more than sufficient for the destinations a Latin American or Hispanic traveler typically visits. If you've used Airalo before, are familiar with their app, and haven't had problems, there's no objective reason to switch just for the sake of it: installation is documented step-by-step in their Help Center, and support is available through the digital channels we reviewed above.
Where it's worth comparing is on two specific and verifiable points: the activation window (fixed in PuraSIM, variable by package in Airalo) and the actual language of support when you write from Latin America. If you're about to buy your first eSIM and don't yet have a preferred brand, checking both options before paying costs nothing and avoids surprises with a specific package's activation policy.
What we won't do here is tell you that one is "better" without being able to support it with verifiable data — that's exactly what this note aims to avoid.
Which physical network you actually connect to
A travel eSIM is not a network of its own: it roams on local operators. Which ones you get decides your real coverage, and almost no provider publishes it. These are the networks a PuraSIM eSIM uses, taken from our own carrier agreements and checked on 2 September 2026.
| Destination | Networks you roam on | Technology | Top-up |
|---|---|---|---|
| Japan | NTT docomo · Rakuten Mobile · KDDI/au · SoftBank | 5G | Yes |
| United States | T-Mobile · AT&T | 5G | Yes |
| Spain | Orange · Movistar | 5G | Yes |
| United Kingdom | O2 · EE · 3 | 4G/5G | Yes |
| Thailand | TrueMove H · DTAC | 5G | Yes |
| Mexico | Telcel · AT&T | 5G | Yes |
| Greece | Wind · Vodafone | 5G | Yes |
| Turkey | Vodafone | 5G | Yes |
Two questions are worth asking about any travel eSIM, Airalo included. First, how many networks you get in your destination: where a plan runs on a single operator you have no fallback if that operator is weak where you are staying. Second, whether the plan can be topped up — if it cannot, running out of data means buying and installing a second eSIM mid-trip.
We publish this table because it is the part of the comparison you can check yourself: land, open your phone settings and read the operator name on screen. PuraSIM covers more than 200 destinations, and the network partners are listed on each destination page.
Frequently asked questions
Do I need to be connected to Wi-Fi to install the Airalo eSIM?
Yes, it is recommended. Downloading the eSIM profile requires a stable internet connection; your physical line's mobile data is usually not enough to complete the installation without interruptions.
Can I install the Airalo eSIM before traveling?
Yes, and in fact, it is recommended to avoid relying on airport Wi-Fi. However, check the activation policy of your package beforehand: in some cases, validity starts counting from when you install the eSIM, not from when you first use it at your destination.
What if my phone is not eSIM compatible?
You simply won't be able to install the profile, no matter which of the three methods you try. Before buying any eSIM package, it's advisable to confirm your specific model's compatibility and that it is unlocked by the carrier.
Can I have the Airalo eSIM and my physical SIM active at the same time?
Yes, that's precisely the point of a travel eSIM: it installs alongside your physical line, not in its place. You can keep the physical SIM for calls and SMS from your usual number, and use the eSIM only for data at your destination.
Does Airalo have phone support?
On Airalo's official help and contact pages that we reviewed on August 10, 2026, a phone number does not appear as a support channel. The channels that do appear are in-app chat, WhatsApp, and email.
How many days do I have to activate the eSIM after purchasing it from Airalo?
It depends on the package: Airalo indicates that each eSIM has its own activation policy, visible before purchase in the "Additional Information" section of the product. It is not a single deadline for their entire catalog.
Can I use the same Airalo eSIM for two different trips?
Once a package is activated and consumed or expires, that data line is no longer valid; for a new trip, a new package must be purchased and installed. The eSIM profile itself can remain stored on the phone, but without active data, it is useless for browsing.
What do I do if my Airalo eSIM stopped having data halfway through my trip?
First, check how much data you have left within the app; if the package ran out, you need to buy a new one or an add-on (where available). If, on the other hand, the package still has data but stopped working, review the roaming settings for that line before assuming the problem is with the package.
In summary
Activating an Airalo eSIM is a process of a few minutes with three possible paths —QR, manual, or direct installation—, as long as you have stable Wi-Fi and a compatible phone. Most "it's not working" issues are resolved by checking two specific settings: which line is selected for data and if roaming is enabled on that specific line, not on the physical one. And the most important detail to check before buying, both with Airalo and any other eSIM, is the activation policy of the exact package you're taking on your trip.
If you are comparing options before deciding, you can check out PuraSIM's international eSIM collection, with 180 days to activate from purchase and 24/7 support via email and WhatsApp in all languages. And if you want to understand the complete eSIM landscape for travel before choosing a brand, the definitive guide to eSIM for travel 2026 covers what no single brand review can cover alone.
