Where to buy a travel SIM: the four options and their catches
At the airport, in a shop in the country, online before you leave, or as an eSIM. What each one wins on and where the small print is.
Tomás Berruezo 5 min Photo by JR Harris on Unsplash There are four places to get data for a trip, and the difference between them isn't so much the price as when you have it and what paperwork sits behind it.
The four
| Where | When you have it | The catch |
|---|---|---|
| Airport counter | On arrival | Queue, opening hours and tourist pricing |
| Operator shop in town | The next day | Registration and sometimes a local address |
| Online, posted to you | Before you leave | You have to order it days ahead |
| eSIM | In minutes, from home | Compatible, unlocked phone |
What changes by country
In some destinations buying a local line takes five minutes with your passport, and in others it means registration, forms and a wait of hours. That paperwork is what decides whether waiting until you arrive is worth it.
And there's one specific case worth looking up beforehand: countries that require you to register a foreign handset if you use a local line for longer than a set period.
What to ask when you buy
- How many days it lasts and when they start counting.
- How much data it includes and what happens when that runs out.
- Whether it works across the whole country or only in one region.
- Whether it can be topped up, and how.
- And that they leave it working before you walk away from the counter.
That last point is what saves you going back the next day.
