Per-GB figures apply the provider's best current code and are calculated on the full plan allowance. Prices are shown in the currency the provider's own feed reports; nothing is converted. Feed data can change, so confirm coverage, availability and the final price at the provider before paying.

Reading the results

Three things this page is doing differently

Lowest price is the wrong sort

Sorted by headline price the top of the list is day passes capped at a few hundred megabytes and expiring in 24 hours. Per gigabyte and validity together tell you the real cost, so both sit on every card and the default order is per gigabyte after the code.

Nothing here is converted

Each provider's feed reports its own currency, and this site holds no exchange rates. Rather than convert with a rate we cannot stand behind, the currency control filters to plans actually priced in that currency. 284,804 plan records are stored in total.

One plan per provider changes the question

A provider with a large catalogue can fill an entire page. The one plan per provider toggle collapses the list to each provider's best offer on the current sort, so you are comparing the market rather than one company's range.
