How we check
Short version: we read the providers' own pages, we write down the date, and we show you when something moves.
We read every price page
Straight from the provider, never copied from another comparison site. Big names every few days, everyone else every two weeks.
We work out the real cost
Providers price in different ways on purpose. We turn all of it into one number: what a gigabyte actually costs you.
We show our workings
Every price says when we last looked. Every change goes in the log. If we get something wrong, tell us and we'll fix it in public.
How “cost per GB” is computed
When a plan is priced per gigabyte, we divide the price by the gigabytes included — a $350 plan with 100 GB is $3.50. Pay-as-you-go rates are shown as listed.
When a plan sells unlimited data for a flat price, a single number would be a lie, so we show a range instead: the flat price spread across heavy use (500 GB a month) down to light use (20 GB a month). And when a pricing model resists the math entirely, the cell shows a dash. We never print a number we can't defend.
How rankings are ordered
Every ranked list on this site is sorted by cost per gigabyte within the set of providers that fit the job on the page — the qualifying rules are printed above each list as chips. There are no editorial scores, no weights we could quietly tune, and the code that sorts the lists cannot see who pays us — that's enforced, not promised.
What happens when we can't check
A provider we haven't successfully checked in 14 days drops out of the default table into a separate strip, clearly labeled — you can still see them, but not by accident. If a provider blocks our checks, we say that on their page. It's useful information about a proxy company.
Corrections
Spotted a number that doesn't match the provider's page? Tell us. Disputes and what we did about them are logged in the public change log — fixes happen in the open or not at all.
