eSIM (embedded SIM) lets you activate mobile data by scanning a QR code. No physical plastic SIM, no shipping, and no traditional roaming charges.

How We Compared These eSIM Providers
To build this list, we looked at:
- Coverage reach (how many countries / regions supported)
- Plan style (local vs regional vs “unlimited” bundles)
- Price per GB for common trip windows (7-day / 30-day)
- Support model (human, chatbot, or email only)
- Agency / reseller friendliness for tour operators
Data points were collected across 10 high-demand corridors: United States, Mexico, Spain, France, Italy, Turkey, the U.K., Germany, Japan, and Thailand.
