It is not possible to unlock the device due to the site not working
Good afternoon, my name is Dmitry, I live in Russia, the city of Omsk. Relatives from America sent me an iPhone 7 as a gift.
However, it turned out to be blocked, on the telecom operator. When creating an application for unlocking an iPhone, it gives an error "Oops! Looks like we're having network difficulties. Try again later."
I've been trying to apply for a month now.
