Does anyone know the mechanism through which phone handsets know what the appropriate display name is for a Cell Broadcast alert? Is it embedded in the message, metadata exchanged when connecting to a cell, baked into the OS, or something else?
Basically I’m curious why some phones got a “Critical AusAlert” in today’s test and others got it as a “Presidential Alert”, in more technical detail than just “that’s what it’s called in America”

@daisy@cloudisland.nz not going to look this up because I know there's a risk that the answer is ACMA requires firmware hack to replace presidential with ausalert in phones sold in Australia

@daisy@cloudisland.nz Is there an iOS/Android split in your data?
