I went out of country with my family in June 2024. Before I went out of country, I called Verizon to add the international plan on 3 phones. I was told it'll be an additional $100.oo per month.
After getting back from out of the country, I called Verizon to inform that all 3 phones are back in the States (California). The Verizon representative that I spoke with asked why I didn't switch to Unlimited Plus for the price and service that I have now, and paid only $10.oo additional for the international plan. I told the representative that I was not advised of that plan.
