Price Index methodology
How the price per GB is derived, destination by destination: formula, sources, scope and limits.
Formula and weights
Price per GB is the median of mid-tier catalogue plans (2 to 49 GB). One GB teasers and 50 GB or larger bundles are excluded: both distort the figure a traveller actually faces. The median is used rather than the mean so a single outlier plan cannot skew the result.

Known limits
Prices come from our own catalogue, not from a survey of the whole market. They track what a traveller pays on this site, and move with our supplier costs.
