      "question": "What is the country code for the U.S. Virgin Islands?",
      "answer": "+1. From abroad, dial your own exit code, then 1, then the national number without its trunk prefix 1. From inside the U.S. Virgin Islands, the exit code for international calls is 011."
    },
    {
      "question": "Which prefixes are mobile numbers in the U.S. Virgin Islands?",
      "answer": "None by themselves. As elsewhere in the North American Numbering Plan, mobile and fixed-line numbers in the U.S. Virgin Islands share area code 340 and their central office codes, and the plan gives both the same pattern (example: (340) 642-1234)."
    },
    {
      "question": "Can a mobile number in the U.S. Virgin Islands be ported to another carrier?",
      "answer": "Not on record. The plan data this page is built from does not list mobile number portability for the U.S. Virgin Islands, so the carrier a prefix was allocated to is likely, not certainly, the carrier serving the number. Only a live carrier lookup (an HLR or MNP query) confirms it."
