Our team specializes in reviewing and testing eSIM services for international travel. We focus on analyzing mobile data solutions — from setup to real-world performance across different countries and regions.

Almas Pounder, our lead analyst, handles hands-on testing. Every eSIM is personally installed, speed-tested, and reviewed based on our experience and feedback from actual users. Our ratings are subjective and meant as practical recommendations rather than official rankings.

How We Test eSIM Services

Before recommending any eSIM, we run a thorough 10-step test process:

  • Brand Research: We check where the provider is registered and what legal jurisdiction it falls under. We read the privacy policy and take note of any data collection practices.

  • Plan & Payment: We purchase a full subscription (with a money-back guarantee) and document all available payment methods — including crypto, if supported.
  • Device Setup and Activation eSIM: We install the app and activate eSIM on iOS and Android.
  • Speed Test: We connect to nearby and remote servers, change protocols, and measure speed, latency, and reliability.
  • Streaming & Gaming: We try to access platforms like Netflix US, Hulu, and Disney+, and test the connection quality for online games.
  • Support & Refunds: We contact customer support to request a refund, tracking available support channels and how long it takes to process.
  • Final Score: We compare results to similar services and give each provider a rating.

We re-test every 6–12 months to check for improvements or issues.
