Stop Looking for a Store
The short answer: You buy an eSIM online, not in a shop.Because eSIMs are software, you can download them from your couch in New York before you even pack for Paris.
Online Providers
(Recommended)
Sites like OVOSIM specialized in travel data. Instant delivery via email/app.
Airport Kiosks
(Expensive)
Shops at LHR, JFK, or NRT charge "tourist prices" (often 3x higher).
Local Carriers
(Hard to setup)
Going to a Vodafone store in Rome requires a passport and language skills.

⚠️ Where NOT to Buy
1. eBay / Amazon Resellers
Never buy a "Pre-loaded SIM" from eBay. These are often registered to stolen identities and can be deactivated mid-trip.
2. "Free WiFi" Apps
Apps promising "Free Global Data" in exchange for ads often install tracking profiles on your phone. Stick to paid, reputable carriers.
