Hello, can a Ukranian phone be used in the US with a US carrier and US phone number?

I have tried everything apple said to do, but I don't have the ability to set up a voicemail at all. All that happens when I click on the voicemail tab is an option to call my non-existent voicemail. I never really needed it before, but I own my own business now so I kinda do.

trouble with connecting phone to computer... trying to find toggle for ap isolation ... I want to make sure it is off

Trying to Numbersync my new S8+ Tablet to my Z Fold 2. I do the steps EXACTLY but when I get to The "Enter code sent to wearable" I dont get a code.  Theres no way to have it send a code.  So I'm basically stuck Why is this such a HUGE (Edited per community guidelines) to set up?  You'd think by

my call and text logs are not accurate on the phones I have on my account. Back and forth messages between phones don't always show up on both phone's logs....

I repaired my new iPhone and everything is set up except the cellular on the watch. I get an error code ERR0093-WS. What does this mean and how dp i fix it?
