How we check the facts, plans and prices on this site

Where facts come from

From primary sources where they exist: Vietnam’s Ministry of Science and Technology and the networks’ own pages, airport operators, Vietnam Customs, the immigration service, the national tourism authority, and the travel advice of the UK and Canadian governments. Weather and seasons come from the tourism authority and that advice. A fact we cannot source is left out or marked as not confirmed.

What “checked” means

The checked date marks the last reading of that page’s sources. It is the same in every language.

Plans and prices

Plans and prices here originate with the store that sells them. Before every release, a check compares each plan’s code, days, data and price with the store’s live page in two languages, and stops the release if anything differs.

Steps and screenshots

Setup steps call the settings exactly what the phone calls them. A phone’s steps get numbers only after they have been tried on that phone.
