Quick answer
Saily is a legitimate eSIM service launched in 2024 by Nord Security, the company behind NordVPN, and rated 4.7 on Trustpilot. Saily is worth it for low prices, top-ups and one reusable eSIM, but it installs only through its app and limits refunds after activation. eSIM.site is an app-free alternative.
