Yesim

Yesim is a Swiss company that works as a marketplace between travelers and carriers worldwide, aggregating 800+ partnerships across 200+ countries. The app includes automatic VPN protection for public WiFi and optional virtual phone numbers, so you can keep your primary number private while abroad. Plans run from a few days to months, with transparent pricing and no hidden markups.

Yesim appeals to security-conscious travelers and those who frequently visit diverse countries. The VPN and virtual number features set it apart from simpler eSIM apps, making it valuable for business travelers or anyone concerned about data privacy on public networks. It's overkill for casual weekend trips but justified for longer journeys or work travel.
