How the facts and plans on this site are checked
On network, airport, place and guide pages, every fact carries its source. No plan or price appears until it has been checked against the store.
- Sources on every page
- Plans checked before release
- Corrections welcome
The short answer
Facts come from the regulator, the networks, the airport operator, government agencies and official travel advice, listed on each page. The checked date is the day we last read those sources. Every plan and price here is compared with the store's live page before every release.
Checked October 2, 2026
Where facts come from
From primary sources where they exist: the NBTC, Thailand’s telecom regulator, the networks’ own pages, the airport operator, the immigration service and its arrival card portal, the Government of Thailand’s visitor pages, and the travel advice of the UK and Canadian governments. A fact we cannot source is left out.
What “checked” means
The checked date is the day those sources were last read for that page. It is the same in every language.
Plans and prices
Plans and prices here come from the store you buy on. Each release begins with a check that compares every plan’s days, data and price against the store’s live page in two languages; any difference stops the release.
Steps and screenshots
Setup steps name the settings as they appear on the phone. Steps get numbered for a phone only after testing on that phone.
