I think they might just get away with it.
That's if they're available at all. In my country, only cell phones certified by the telecommunications government agency (ANATEL) can be imported, so the alternatives (Jolla, PinePhone, Fairphone) simply don't exist.
They do marvellous things like mandate weird Brazilian Android games on the phone I bought in Brazil.
Maybe I think too highly of people, but I'd also imagine most would be able to get say... 6/10 right, for which countries the following list is from:
- Flanders
- Nova Scotia
- Brandenburg
- Guangzhou
- Tasmania
- Minas Gerais
- Catalonia
- Chechnya
- West Bengal
- Bali
