Buy IPhone 12

Dear seller!

my name is Alyona. I’m a huge fan of apple products.

I live in Ukraine. Unfortunately we don’t official retailer. I am afraid to buy locked under American cells operator. I had such an experience 4 years later, it was licked under AT&T. After installation of a new updated version it couldn’t find cell operator, so i had to buy a nee one.

I want to buy a new iPhone 12 Pro in the nearest future. Can I order it from official website in US? I have a delivery address in US. Will this phone connection with foreign (Ukraine) mobile operator? I use Vodafone(MTS Ukraine). Will it work correctly? Can I install Russian language? Will it work correctly after I update a new IOS version?

Thanks in advance
