A Europe eSIM saves buying a new SIM at every border: one eSIM, one plan, from Lisbon to Kraków. We compared the Europe plans of five providers on what decides the choice: the price for the data you need, which countries are covered, and what "unlimited" really gives you each day.
How we ranked them
- Price for the same data: the cheapest plan at or above 1, 3, 5, 10 and 20 GB, in US dollars before coupons.
- Unlimited data: the price for a week and how much full-speed data you get each day before the speed drops.
- Coverage: the countries most trips include (France, Germany, Italy, Spain, the UK, Switzerland, the Netherlands), and extras such as Türkiye.
- ONE eSIM is our own service. It is ranked by the same numbers as the others, and the table shows where a rival is cheaper.

- Saily: best unlimited value. 5 GB a day at full speed for $26.99 a week: the most full-speed data a day of the capped plans here, for about the same price as Airalo’s 3 GB a day. Its fixed plans cost about two and a half times ours.
- Holafly: best with no daily cap. $27.50 a week with no set daily allowance, for heavy streaming every day. It sells unlimited plans only.
- Airalo: wide coverage. One plan for 41 countries and short plans from 3 days; its unlimited plan slows after 3 GB a day by default.
- Nomad: short unlimited trips. 2 GB a day for $19 over 5 days; fixed plans from $5.50 for 1 GB.

How we check prices
We read each provider’s public Europe page on 27 October 2026 and took its cheapest plan at or above each size, in US dollars before any coupon or sale credit, with the validity in brackets. Nomad shows prices in the visitor’s currency; its figures here are its own USD list prices. ONE eSIM prices are our live list prices on the same day. Prices move, so we re-check every month. If a number is out of date, write to support@oneesim.app and we will correct it.
