Best eSIM for Travel 2026: 5 Providers Ranked
Five travel eSIMs ranked on price, unlimited data and coverage, from our dated price checks: ONE eSIM, Saily, Holafly, Airalo and Nomad.
Short answer: On price, ONE eSIM: it had the cheapest 1 GB plan in 54 of the 58 countries in our price index and the cheapest unlimited plan at 1 and 2 GB a day in 22 countries (both checked 27 October 2026). For unlimited data above 2 GB a day, Saily or Holafly is often the better buy, and Airalo has the widest choice of regional plans.
The best travel eSIM depends on how you travel: how much data you use, whether you need unlimited data, and how many countries are on the route. We rank five providers on prices we check every month and say who each one suits, including where ONE eSIM is not the best pick.
How we ranked them
- Price: the 1 GB price in 58 countries (the price index) and the 1 to 20 GB prices on each country comparison.
- Unlimited data: the price for a week by full-speed data a day, in the unlimited comparison.
- Coverage and choice: single-country, regional and global plans.
- ONE eSIM is our own service, ranked by the same published numbers.
The ranking
- ONE eSIM: best price. Cheapest 1 GB in 54 of 58 countries and cheapest unlimited at 1 and 2 GB a day in 22. Plans for 200+ destinations, with the networks and 5G named on every plan. Pick a rival for heavy unlimited use or if you want a long-established brand with many reviews.
- Saily: best daily unlimited allowance. 3 to 5 GB a day at full speed, and the cheaper unlimited plan from 3 GB a day in most of the 22 countries we compared.
- Holafly: unlimited with no daily cap. The simplest choice for heavy streaming; it sells unlimited plans only.
- Airalo: widest choice. The best-known brand, with many regional plans; prices are usually higher than ours for the same data.
- Nomad: flexible short plans. 2 GB a day unlimited plans in many countries and fixed plans from 1 GB.
Which travel eSIM should you choose?
- Light use (maps, messages, booking apps): the cheapest fixed plan; check your country on the price index.
- Up to 2 GB a day: ONE eSIM’s daily unlimited plans in Europe and China; elsewhere compare by GB a day.
- Heavy streaming every day: Saily’s 5 GB a day plans or Holafly’s no-cap plans.
- Several countries: a regional plan. Our Europe and Asia pages show which one covers your route.
