Remember the old airport ritual: hunting down a phone shop, handing over your passport, filling in forms, and prising out your SIM card with an earring? That whole experience has quietly disappeared. eSIMs are downloaded digitally, often before you even leave home, and according to travel writer Adventurous Kate's new roundup of the best travel eSIMs for 2026, there's no good reason to go back to the plastic-card era.
An eSIM is simply a SIM card that lives inside your phone as software rather than a chip. Nearly all recent handsets support them — iPhone XS and later, Samsung Galaxy S20 and up, Google Pixel 3 onwards — though older and budget Androids often don't, so check before buying.
Why bother at all? Kate, who has spent 16 years coaching travellers (especially women) on staying safe abroad, argues mobile data is a safety tool as much as a convenience. It lets you hail a rideshare when a situation feels wrong, keep your blue dot on Google Maps in places like Venice or Lisbon, run Google Translate on menus and conversations, and catch gate changes at airports with patchy wifi. The alternative — relying on your home network's roaming — can be brutal. Americans in particular have come home to bills of $200-400; Kate herself once paid $80 for a single week in Antigua in 2019.
So which eSIM should you pick? Kate's overall winner is Holafly, which sells unlimited-data plans by the number of days you're travelling, runs on major local carriers, covers 200+ destinations, and throws in 1GB of free emergency data per month across 150+ countries via its Always On feature — handy for delayed flights and surprise layovers. There's a six-month refund window and monthly subscription plans for long-haul travellers; the code HOLAKATE takes 5% off.
Light users have cheaper options. Airalo's plans start around $4 and its app makes buying and topping up easy — fine for maps and WhatsApp, but heavy users will burn through data and rack up top-ups. Saily, from the NordVPN team, bundles an ad blocker, web protection and a virtual location tool, with short plans under $4 and coverage in 150+ destinations (though its unlimited plans throttle after a daily high-speed allowance). If you genuinely need to make and receive calls, SimLocal includes a local number and SMS on many plans across 200+ destinations, from 7 to 90 days. And Breeze keeps things minimal — no app required, plans valid 12 months — but its unlimited plans throttle hard after just 1GB a day and support reviews are mixed.
A few quick rules of thumb from the guide: for multi-country trips, buy a regional eSIM (Europe, Balkans, Southeast Asia) rather than an expensive global one; check whether top-ups work without wifi; and decide if you actually need a local number — for most travellers, WhatsApp plus Google Voice covers it. Installation is usually a QR code scan or one-tap on newer iPhones, and no, eSIMs don't drain your battery any faster than a regular SIM.
For anyone travelling in 2026, this is one of the easiest wins going: a few dollars and two minutes of setup can save you an hour in a phone shop and a four-figure phone bill. Full rundown courtesy of Adventurous Kate.
