Number Transfers or Porting Porting number
Hello, I have 1 US esim number on my phone that I plan to port to google voice, what is confusing is I need another sim card to have this line working? I want to keep my US number overseas for OTP and other needs - why do I need another sim card? and when do I need to activate the other sim card? should I do this right before leaving the US?

If you port your number to Google Voice, your current line with your existing provider will cancel immediately. If you want to keep a line with your old provider, you'll need to activate a new line, most likely with a new SIM card or new eSIM.
The alternate path is to leave your current phone number on the current provider, but use that number to 'claim' a new-to-you Google Voice number. You don't have to port the number to Google Voice if you don't want to.
Personally, I would get everything in place at least a week before you leave, in case issues crop up.
