Holafly

A two-week trip through five European countries makes buying separate country-specific eSIMs impractical, which is exactly the situation Holafly's regional Europe pack is built for: one unlimited profile covers dozens of countries across the continent, so crossing from France into Spain into Italy doesn't require touching your phone's settings at all. Pricing is flat regardless of how much data you use or how many of the covered countries you actually visit, running around $75 for 30 days in most cases.

The fair-use policy that applies to Holafly everywhere applies here too: independent tests have shown speed drops after somewhere between 4.5GB and 10-15GB of daily use, with full speed back the next day, so treat "unlimited" as generous rather than literally infinite. Hotspot tethering carries its own separate daily cap. Everything is data-only, with 24/7 chat support if you run into trouble mid-trip. It's the clear choice for a multi-country European rail trip or road trip over a single-country visit, where a cheaper country-specific plan usually makes more sense.
