We have two iPhones on the Nationwide plus Mexico family share plan. We are currently in an area of Mexico where we receive service (and received great service with no additional fees last year with a Droid X on the "extended" network). My husbands iPhone 4S says "extended" but my iPhone 5 says "roaming". Does this mean that his calls will be included in our plan but Verizon will try to bill mine as roaming charges? Confused and don't really want to have to deal with an additional bill upon our return. Any answers would be appreciated.
