How we compare prices

Airalo prices come from Airalo’s public country and region API. Holafly prices are read from the USD table on each Holafly destination page. Saily, Nomad, Ubigi and Maya Mobile prices come from a public catalog that re-checks those providers’ feeds; the plan row links to that catalog request and to the provider.

Plan speed badges use only what the provider published: 4G, LTE or 5G, the local operator names when they are in the feed, and a post-cap speed such as 1 Mbps only when that figure is written in the plan’s fair-use text. Each badge names the source URL and the check date. If a field is missing, we leave it off. We do not estimate a megabit rate, and we do not collect speed tests from visitors.

USD is the currency the providers were priced in. GBP and EUR use European Central Bank rates via Frankfurter, dated on the currency control. Trip length counts both the depart and return dates. “Days of data” divides the allowance by the same MB-per-hour rates as the data calculator.
