Airalo
AIThe largest eSIM marketplace, covering 200-plus countries and regions
Airalo is the biggest name in travel eSIMs, with prepaid data plans for nearly every country plus regional bundles for multi-country trips. The app lets you install and switch eSIMs before you land, so you skip the airport SIM kiosk entirely. It's the default choice when you want one app to cover almost anywhere you'll go.
What it actually is
Airalo is an eSIM marketplace, not a mobile carrier. It resells data plans from local network partners in more than 200 countries and regions through one app, so you can buy and install an eSIM before you land. For a nomad crossing a border every few weeks, that means skipping the SIM kiosk hunt at 1am and the passport handoff to a shop that may or may not sell you the plan you actually need.
How the plans work
There are three plan types: Local (one country, e.g. Japan 5GB), Regional (multi-country bundles, e.g. a Europe pack spanning dozens of countries), and Global (140-plus countries in 10GB or 20GB packs). Small local plans run around a few dollars per gigabyte, and the larger global bundles cost tens of dollars. Most plans are data-capped rather than unlimited, and the unlimited options throttle to about 1Mbps after 3GB of use in a day. That covers maps and messaging, but not a video call.
Where it falls short
Coverage skips a few sanctioned markets like Iran and North Korea, so those routes need a local SIM instead. Speed depends on which local carrier Airalo partnered with in that country. In Thailand, for example, Airalo often runs noticeably slower than a local SIM: fine for basic connectivity, but not a replacement for a proper local plan if you are staying weeks. Support can be slow too, and activation problems have left some users waiting hours, which is exactly when you need to be online.
Our take
Airalo earns its keep in the first 48 hours in a new country: land, get online, and sort the rest out later. It is not the plan to run on for a month-long stay. Once you are settled somewhere, a local SIM is almost always cheaper per gigabyte and faster, so check that price before you renew an Airalo plan out of habit.
What works
- Covers 200-plus countries and regions in one app, so you land already connected instead of hunting for a SIM shop
- Regional and global bundles cover multi-country trips without buying a new SIM at every border
- Install and activate before you fly, useful for red-eye arrivals with no working signal yet
- Widely used and reviewed, so pricing and coverage per country are easy to check before buying
What to watch
- No coverage in a few sanctioned markets like Iran and North Korea, so you need a backup there
- Speed depends on the local partner carrier and can lag well behind a local SIM (Thailand is a commonly cited case)
- Nearly all plans are data-capped, and the unlimited options throttle hard after about 3GB in a day
Questions at the counter
Does Airalo work in every country I'll travel to as a nomad?
Not quite. It covers 200-plus countries and regions, but a few sanctioned markets like Iran and North Korea are excluded. Check the specific country page in the app before you rely on it as your only connection.
Is Airalo cheaper than buying a local SIM?
Usually not per gigabyte. Local SIMs in most countries beat Airalo on price and often on speed, since Airalo is reselling access through a local partner. The trade-off is convenience: you are connected the moment you land instead of spending your first hours in a new country hunting a SIM shop.
What happens on the unlimited plans when I use a lot of data?
Airalo's unlimited plans throttle to around 1Mbps once you pass roughly 3GB of use in a single day. That is workable for messaging and maps, but less so for video calls or large uploads.
Can I keep multiple Airalo eSIMs installed at once for different countries?
Yes, that is the main appeal for route-heavy nomads. You install eSIMs ahead of a trip and switch between them in the app as you cross borders, without physically swapping a SIM card or losing your home number's eSIM slot if your phone supports multiple profiles.
