eSIM Travel Data Cost Calculator
Every eSIM provider publishes its own pricing page and none of them mention the other two. Enter your trip length and data needs, line up the providers you're considering, and see who actually comes out cheapest. Nothing uploaded.

Comparing eSIM provider pricing models
How per-GB and flat-fee bundles affect your total trip cost
eSIM providers use two pricing models. Per-GB rates charge a fixed price for every gigabyte you use - straightforward but potentially expensive if you use more data than expected. Example: Airalo charges $1.50/GB for some regions. A 10-day trip using 5GB costs $7.50. But if you accidentally use 8GB, the cost jumps to $12. Flat-fee bundles charge one price for a fixed data amount over a fixed number of days - e.g. Holafly's $20 for 10GB over 7 days. The bundle is better if your usage is predictable, but requires you to buy multiple bundles if your trip exceeds the bundle duration. A 15-day trip needing 10GB for 7 days each would cost approximately $40 (two full 7-day bundles at $20 each, or $20/7 pro-rated for the 8th day). This calculator shows you both models side-by-side so you can see which is cheaper for your specific trip." }
Why provider examples change and how to verify prices
Airalo, Holafly, and Saily update their prices monthly and vary them by destination country, season, and promotion status. The example prices in this calculator are illustrative only - they show how the comparison works, but they may not reflect current real-world pricing. Always visit each provider's website directly before booking, enter your exact destination and travel dates, and verify the price and data limits they show you. The calculator is a tool to help you compare pricing models, not a real-time price tracker." }
FAQ
What is the difference between per-GB pricing and a flat-fee bundle?
Per-GB pricing means you pay a fixed rate for each gigabyte you use - e.g. $1.50/GB means 1GB costs $1.50, 2GB costs $3, etc. Flat-fee bundle pricing means you pay a fixed price for unlimited or capped data over a set number of days - e.g. $20 for 10GB over 7 days. Bundles are better if you know your trip length; per-GB is better if your usage is unpredictable. This calculator lets you mix both types and compares their total cost for your specific trip.
How does this calculator handle trips longer than the bundle duration?
If your trip is 15 days and a bundle covers 7 days, the calculator purchases multiple bundles: two full 7-day bundles (14 days) plus one partial day from a third bundle. Example: if you need 10GB for 15 days and choose a provider's 10GB/7-day bundle at $20, the calculator charges you for two full bundles ($40) plus the pro-rated cost of one more day ($20 / 7 ≈ $2.86), totalling about $42.86 for the 15-day trip.
Are these provider prices current and what should I verify before buying?
No. The example providers (Airalo, Holafly, Saily) in the calculator are illustrative starting points - prices change frequently and vary by country. Before you buy an eSIM, go directly to each provider's website, enter your destination country and trip dates, and verify the exact price and data limits they show you. This calculator does the math for whatever prices and data amounts you enter, but you must confirm real-world pricing before purchasing.
