How it works
Transparency is our core value. Here's how we calculate your travel data savings.
Where do you get the carrier roaming costs and benchmarks?
Our calculator utilizes a regularly updated database of international roaming benchmarks for major global carriers, including US-based telcos like AT&T, Verizon, and T-Mobile (based on their International Day Pass rates), as well as UK carriers such as EE, Vodafone, and O2, and major European providers. We specifically track the lowest entry-level daily roaming fees that offer high-speed data access. By comparing these standard fees with our wholesale-priced local eSIM rates, we can provide a highly accurate projection of the potential savings you can expect during your specific trip duration and destination.
How accurate is the 'Best Plan' matching engine?
The matching engine scans over 5,000 active eSIM packages in our real-time database to identify the optimal configuration for your trip. It analyzes your selected 'usage profile'—whether you're a light user primarily using messaging or a heavy user streaming video and using navigation—and maps that against the most cost-effective plan that covers your entire trip duration. We prioritize plans that offer the best balance of data volume and validity duration, ensuring you don't overpay for unused data while never running out of connectivity when you need it most.
Is this calculator suitable for business travelers and digital nomads?
Absolutely. Business travelers and digital nomads are often the most affected by exorbitant roaming fees because they require consistent, high-speed connectivity for communication, video conferencing, and cloud-based applications. A typical heavy usage profile (2GB+ per day) can cost over $100 per week with traditional US carriers using daily passes. Our calculator demonstrates why enterprise-grade connectivity through regional or country-specific eSIMs is often ten times more economical, providing the same native 5G performance without the corporate roaming price tag.
