Why the numbers can be trusted

Data rates come from the app makers' and carriers' own help pages, plug standards from two independent references, and eSIM prices from each provider's country page. Every figure carries the page it came from and the date it was read, and the methodology page shows the arithmetic. Where a source gives a range, the site shows the range rather than picking a number.
