12 brands compared, not an exhaustive listWhy this ranking?
Compared on price per GB: for each trip, each brand's cheapest plan that covers the duration and the data, at the public price we checked, divided by its GB (at most one and a half times the data requested); for unlimited, the price. Average gap: the mean, over the trips compared, of the difference between the two brands relative to the better ranked one.
Not an exhaustive comparison: 12 brands out of the dozens that sell eSIMs. The list of brands compared is in our Methodology.
