The Best eSIM for Traveling Europe (Updated 2025)

"When I travel to Europe I use Holafly eSIMs because they provide international eSIMs for travelers, covering over 170 countries worldwide and specifically offering service in 32 countries across Europe; their plans run from 5–90 days (priced around 19–99 EUR, with plans sometimes listed starting at $19 USD) and all European plans include unlimited data, which I consider the biggest highlight. I buy via their website or app, follow emailed setup instructions to install via QR code or manually (there's also one-tap automatic installation on iOS 17.4), and rely on their 24/7 support if anything goes wrong. Holafly lets me keep my physical SIM to receive calls, retain my WhatsApp number, top up online, and avoid the hassle and cost of roaming or buying multiple physical SIMs when visiting multiple countries, though their Europe plans do not allow data sharing/hotspotting." - Matthew Kepnes
