    },
    {
      "question": "What is the country code for Guam?",
      "answer": "+1. From abroad, dial your own exit code, then 1, then the national number without its trunk prefix 1. From inside Guam, the exit code for international calls is 011."
    },
    {
      "question": "Which prefixes are mobile numbers in Guam?",
      "answer": "None by themselves. As elsewhere in the North American Numbering Plan, mobile and fixed-line numbers in Guam share area code 671 and their central office codes, and the plan gives both the same pattern (example: (671) 300-1234)."
    },
    {
      "question": "Can a mobile number in Guam be ported to another carrier?",
      "answer": "Not on record. The plan data this page is built from does not list mobile number portability for Guam, 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."
