Everything you need to know about eSIMs, installation, device compatibility, and staying connected when you travel.
Every traveller you send abroad buys mobile data. With a discount code that gives them 10% off, you earn 12% on every sale, again on every repeat order. How agencies and group leaders make money from it on Instagram, WhatsApp and in their own bookings.
What daily roaming really costs a company, and how an eSIM for every traveller replaces it: the work number kept, laptop data sized, frequent travellers sorted, and teams and event attendees connected on one quote and one invoice.
Europe's Entry/Exit System replaced the passport stamp with a face scan and four fingerprints, and the queues made the news. What happens at the border, who is exempt, the 90-day count, the ETIAS delay, and how to land with data before you join the line.
Booking data for a tour group, a school trip or a company team is a different job from buying one eSIM. How group bookings work, from the quote to each traveller's install email, and how agencies earn on every eSIM their travellers buy.
Five to twenty gigabytes cost half of Airalo’s price or less, Brunei costs several times as much as Malaysia, and the train from KL now runs straight to Johor Bahru. What to buy for Kuala Lumpur, Penang, Borneo and a day across the causeway or the Thai border.
Shenzhen is 14 minutes from West Kowloon and Macau about 40 minutes over the bridge, and a Hong Kong plan stops at both borders. Three days of unlimited cost the same as a ten-gigabyte month. What to buy for a stopover, a week in the city and day trips across the border.
Tromsø’s aurora tours sometimes finish the night in Finland, Svalbard sits outside Europe’s roaming rules, and Russian signal reaches Kirkenes. Norway’s own data costs the same as France’s. What to buy for the northern lights, the fjords, the coastal voyage and a few days in Oslo.
A week of unlimited data in France costs less than a twenty-gigabyte month, one of our two cheapest Europe plans has no France on it, and every Métro tunnel in Paris has had 4G since 2020. What to buy for Paris, the Riviera, day trips over the border and a house in the country.
A week of UK unlimited costs exactly what a twenty-gigabyte month does, Jersey and Gibraltar need their own cover, and a Giant’s Causeway tour from Dublin crosses a border with no checks. What to buy for London, Scotland and a UK and Ireland trip.
On the islands facing Turkey and Albania, a phone can roam out of Greece while you sit on the beach. Who that costs money, the two-minute fix, what a day trip to Bodrum or Sarandë should run on, and where our Greece prices sit against Airalo’s.
Everything in Iceland costs more than you expect. Data is the exception. Here is what a Ring Road trip actually needs, where the coverage stops, and why the usual advice to buy the smallest plan is wrong here.
Your EU contract roams free in Italy and Austria and stops at the Swiss border. Liechtenstein, twenty minutes away, is still included. Here is why, what it costs, and the plan sizes worth buying for a Swiss trip.
Spain is one of the cheapest countries in Europe to buy travel data for, which is exactly why the money gets lost on the shape of the plan rather than the price of it. The table, the arithmetic, and what to buy for the trip you are actually taking.
Our live South Korea prices next to Airalo's, and the three decisions that cost travellers more than the provider they pick: the wrong regional list, the combined Japan plan, and buying too little data for a country where Google Maps cannot navigate.
Your Europe plan covers a list of destinations, not a map. Monaco, Andorra, the Faroes and Greenland are on none of them, Guernsey is on one of five, and the price for the same data runs from identical to ten times higher.
Martinique and Saint Lucia are twenty-five miles apart and data costs nine times more on one of them. A Caribbean buying guide organised the way the prices actually fall: island by island.
The slot disappearing from phones is not about the model you bought. It is about the country you bought it in. What that changes the moment you land, and the check to run before you fly.
Airalo's Latin America plan and Lumbus priced side by side, then what to buy for Brazil, for the Gringo Trail, and for a three-month overland run, and why the plan named after the continent is rarely the answer.
Airalo and Lumbus priced side by side for India, then why the country with the cheapest mobile data on earth is one of the dearer places for a visitor to buy it, and what that does to every usual rule.
Most European trips are solved by buying a Europe plan. A ski trip is the exception: several of the best-known ski countries are on no Europe coverage list, and the one that catches most people costs around three times what France, Austria or Switzerland cost at the same size.
Airalo and Lumbus priced side by side for Indonesia, then the rule that matters more than price in Bali: the network checks your handset, and a travel eSIM sits outside that check.
Airalo and Lumbus priced side by side for Thailand, then what to buy for a city, an island and a border hop, and the admin you cannot do once you are offline in an arrivals hall.
An eSIM has two clocks, and only one of them forgives you. Running out of data is fixable in about a minute. Running out of days is not, and that is the one worth understanding before you travel.
Every Christmas market country costs the same for data, from Norway to Croatia. What changes the bill is how many of them you visit, and the crossover is not where most guides say it is.
Airalo and Lumbus priced side by side for Turkey. Then the two things that catch people out, which have nothing to do with price: buying from inside the country, and a device rule that can switch a phone off after 120 days.
The honeymoon shortlist splits into two price worlds, and it has nothing to do with how luxurious the resort is. Here is what data really costs on the islands, whether two people need two plans, and the plans that quietly waste money.
Airalo and Lumbus priced side by side for the UAE, then the answer people actually want first: app calls are blocked across the country and no data plan changes that. What an eSIM does give you in Dubai, and how much to buy.
Airalo and Lumbus priced side by side for Japan, then the part that actually costs people money: buying the wrong shape of plan. A regional plan you don't need, a one-week plan that costs the same as a month, or unlimited when a fixed plan would have done.
Airalo and Lumbus priced side by side for the United States, then the only real decisions: how much to buy, and whether Canada or Mexico belongs on the same eSIM. Plus the territory trap that catches people flying to San Juan.
A business trip to London is a different data problem from a holiday: shorter, denser, laptop-shaped, and expensed. Conference Wi-Fi and its captive portals, the Underground's half-finished signal, and what to buy for two days, six months of trips, or a whole delegation.
A Grand Prix is the hardest place on earth to send a video, and the easiest trip to buy data for, because the calendar tells you exactly where you'll be. The race-day network problem explained, plus the one-plan trick for the Austin–Mexico City and Qatar–Abu Dhabi double-headers.
The queue at the arrivals-hall SIM counter and the passenger walking straight past it are solving the same problem at very different prices. What airport SIM kiosks actually sell, the paperwork and hours nobody mentions, when they beat an eSIM, and how to land already online.
Connected, but everything crawls? The eSIM itself is never the bottleneck. How to read 5G, LTE and 3G next to your signal bars, switch to a faster network by hand, spot the unlimited plan's daily speed reset, and fix slow travel data in five minutes.
In port, a travel eSIM puts you on the local network in minutes. At sea, it shows no service and spends nothing, and that second part is the feature. What to buy for each cruise route, and the one switch that prevents the horror-story bill.
Buy your travel eSIM months ahead if you like: it keeps for 180 days, installing it doesn't start the clock, and an uninstalled eSIM can be refunded. The details, including the trap that does start it early.
Airalo's regional Asia plan and Lumbus priced side by side, then which of four coverage lists to pick. One has no Philippines, one has no Cambodia, one has no Taiwan, and the cheapest has no Japan.
Airalo's regional Africa plan and Lumbus priced side by side, then the thing worth checking first on this continent: the price, because it varies here more than anywhere else.
Airalo's regional Europe plan and Lumbus priced side by side, then the choice that matters more: the coverage lists differ, and one of them leaves out France.
Airalo's Middle East and North Africa plan and Lumbus priced side by side, then the catch: regional plans disagree about which countries are in the Middle East, and the one you bought may not cover Oman.
Nobody warns you about the three-week gap between landing and being able to open a local phone contract. That gap is the actual problem to solve.
Two different eSIMs get confused for one another here, and they have opposite answers. Work out which one you're moving before you delete anything.
A customer called us a British eSIM company like it was a relief. It's worth explaining what that actually buys you, and what it doesn't.
The technology is a published standard and it's at least as secure as the plastic SIM it replaces. The part that actually deserves your attention is who you bought it from.
One is a plan inside your phone. The other is a second gadget with its own battery and a return deadline. Here's when each is genuinely the better buy.
Most roaming bills aren't earned by browsing. They're earned by a phone doing its normal background job on a foreign network. Here's how to stop it.
Four things your screen might be telling you, and a different fix behind each. Start with the symptom, not the settings menu.
One plan that survives every border crossing, or a cheaper plan per country? The honest arithmetic, region by region.
Unlimited doesn't mean unlimited fast. Here's exactly how these plans work, and when they're the cheaper choice.

An honest comparison of the three main ways to get mobile data when you travel, and how to choose the right one.
A plain-English guide to what an eSIM is, how it works, and why it's the easiest way to stay connected when you travel.
