Each price is read from the provider's own website in USD on the date shown in its row; we do not convert currencies. The trip is split evenly between the two countries; data needs are 0.3 GB/day (light), 0.8 GB/day (standard), 1.8 GB/day (heavy). Plans are ordered by price for the standard trip, then by price per GB. We do not test network speed or support. Full methodology.
