About & method

Every record comes from an official carrier or manufacturer page, linked next to the data with the date we last checked it. If a carrier doesn't say something, we mark it unknown rather than guess.

Where a carrier states a rule rather than a list (e.g. Apple: “iPhone 14 or later”; Kyivstar: “iPhone 13 and newer”), we apply the rule to known model names and say so in the note.

A script refetches every source weekly and flags changes for review. See What changed.
