Per-GB pricing versus flat-fee bundles
The calculator prices each provider one of two ways. A per-GB provider costs price per GB times the data you need. A flat-fee provider sells a bundle for a set number of days, and since partial bundles are not sold, the calculator rounds your trip up to a whole number of bundles.
With the default trip of 10 days and 5 GB, a per-GB plan at $4.50 per GB costs $22.50. A $19 bundle that covers 5 days needs two bundles for 10 days, so it costs $38.
Where the cheaper option flips
The flat-fee total depends on days only and the per-GB total depends on data only, so each one can win on a different trip. Take 12 GB at $3 per GB, which is $36, against a $22 bundle covering 7 days. On a 7-day trip the bundle costs $22 and wins. On an 8-day trip you need two bundles, so it costs $44 and the per-GB plan wins.
The flat-fee price assumes the bundle covers all the data you need. The calculator does not check that against any daily limit, so read the plan's terms.
What "unlimited" can hide
The Gone Goat's roundup of Europe eSIM plans says many so-called unlimited plans slow you down after a certain threshold and only offer 500 MB or 1 GB per day. It describes one provider as offering up to 10 GB per day at full speed. Compare what you will use each day against a plan's real daily limit, not the word "unlimited".
FAQ
How do I estimate the data I need?
Enter your best guess for the whole trip in GB. The calculator takes the number as given, so a higher estimate costs more on per-GB plans and does not change flat-fee prices. Check how much data your phone used on a similar trip.
Does the calculator check coverage?
No. It compares only the price, trip length and data you enter for each provider. Check that every plan covers the countries on your route before you rely on the ranking.
Are the example prices current?
No. The two starting rows are examples labeled "verify". Replace them with the live price from each provider before you decide.
