**There is no universal "best eSIM"** — only the best for your profile. Light data users want Airalo or Saily by the GB; streamers and remote workers want Holafly unlimited; price hunters look at Saily and Nomad.
**Airalo** is the broadest (200+ countries/regions) and the market standard per GB, but rarely the cheapest. It wins on hard-to-reach countries and reliability.
**Holafly** sells almost only **unlimited data** at a price per day, with no volume to track — great if you don't want to monitor GB, pricey for short light-use trips.
**Saily** (by Nord Security, maker of NordVPN) is the **most aggressive on price per GB** in 2026, with a built-in VPN and ad blocker. Smaller coverage than Airalo, but covers nearly every popular destination.
**Nomad** shines on **large bundles** (10-20 GB), where price per GB drops sharply with volume, and offers generous referral credits.
