The old routine on landing: find the phone shop past baggage reclaim, queue, hand over your passport, wait while a form is filled in, receive a SIM, discover the tiny tray tool is in your checked bag. Airalo replaced that with buying a plan on the plane and having data before the cabin doors open.
It is not the cheapest way to get connected abroad. It is the one that works with the least thought, and after several years of the category maturing it remains the default for good reasons.
What it costs
Airalo prices by destination and data volume. The shape of the catalogue as of 2026:
Local plans start around $4 for small data allowances in a single country.
Regional plans cover a continent or a bloc at intermediate prices.
Discover global plans cover 167 countries, from roughly $8.50 at the entry level up to about $66 for 20GB valid for 365 days.
Larger global packages run to $159 for high-volume 30-day plans.
Some destinations have unlimited-data options, with three-day unlimited starting around $11.50 in certain countries.
For a week in one country with normal usage — maps, messaging, occasional browsing — expect to spend in the region of $5–15. Against a typical carrier roaming charge that is a large saving. Against a local physical SIM bought in a supermarket it is usually a modest premium.
What you give up
A phone number. Most Airalo plans are data-only. You get internet; you do not get a local number for calls or SMS. In practice that matters in three situations: booking a taxi through a local service that SMS-verifies, a restaurant or guesthouse that wants to call you, and any local service requiring a domestic number to register.
If you need a number, a local physical SIM is still the answer, or a plan from a provider that includes one.
Price. In countries with competitive prepaid markets — India, Indonesia, much of Latin America, Thailand — a local SIM bought in a shop offers dramatically more data for less money. If you are staying a month, go and buy one.
Network choice. Airalo resells capacity from local network partners, and which partner you land on is not disclosed before purchase. In most countries the difference is immaterial. In a few — mountainous areas, rural regions where one network dominates — it is not, and you cannot choose.
What you need
An eSIM-capable handset that is carrier-unlocked. Most flagships since roughly 2019 qualify, and several recent models are eSIM-only. Older or regionally locked phones do not. Check before you buy a plan; refunds on an unusable eSIM are a conversation nobody enjoys.
Practical use
Buy and install the eSIM before you fly, while you still have reliable wifi.
Do not activate until you land — most plans start counting on first connection.
Keep your home SIM active for calls and SMS, with data disabled to avoid roaming charges.
Set the eSIM as the data line and your home line as voice.
Top up in the app rather than buying a second plan.
The competition
Saily, Holafly, Nomad, Ubigi and others compete directly, and several undercut Airalo on price. Holafly's unlimited plans are attractive for heavy users; others are cheaper on specific regions.
Airalo's advantages are breadth — few competitors match the number of destinations — and reliability of activation, which is the thing that actually goes wrong in this category. Paying two dollars more for an eSIM that provisions correctly the first time is a trade most travellers should take.
A worked comparison
Take a fortnight in Japan for one person with ordinary usage — maps, messaging, a few hours of browsing, no video streaming. Call it 5GB.
Carrier roaming, on a plan without an international add-on, is the worst option by a wide margin and the one most people default to.
A roaming day pass from a home carrier at a typical daily rate runs into the tens of pounds over fourteen days.
An Airalo Japan plan at that data volume sits in the low-to-mid tens of dollars, purchased before departure and working on landing.
A physical Japanese tourist SIM bought at the airport is broadly comparable and sometimes cheaper, at the cost of a queue and a form.
A cheaper rival eSIM may undercut Airalo by a few dollars.
The gap between the first two options and the last three is large. The gap among the last three is small. That is the honest shape of this market: the decision that saves you real money is choosing an eSIM or a local SIM at all, not which one.
When not to use an eSIM
Three cases where a physical local SIM is still the right answer: stays longer than a month, where local prepaid economics win decisively; countries where you need a domestic number for ride-hailing, delivery or bank verification; and destinations where one network dominates rural coverage and you need to be on that specific network.
Verdict
8.0. Airalo solves a genuine, universal travel annoyance with a product that works on the plane, costs less than roaming, and requires no interaction with anyone at an airport.
It is held out of the higher bands by being data-only on most plans, by being beatable on price both by local SIMs and by newer rivals, and by the undisclosed network partner. For a short trip or a multi-country itinerary, it remains the one to buy.
