I asked similar question before buying from where I live, luckily my cc M4 didn't encounter customs stuff
nostr:npub1az9xj85cmxv8e9j9y80lvqp97crsqdu2fpu3srwthd99qfu9qsgstam8y8 would it be possible to put a literal calculator program on the Coldcard before shipping to bypass Vietnamese customs?
Could flash it with coldcard firmware once it’s passed customs?
