      "question": "What is the country code for the British Indian Ocean Territory?",

    {
      "question": "Which prefixes are mobile numbers in the British Indian Ocean Territory?",
      "answer": "Mobile numbers start with 38 in national form; the mobile regular expression on this page gives the exact ranges (example: 380 1234). The carrier table shows which prefix blocks were allocated to which operator."
    },
    {
      "question": "Can a mobile number in the British Indian Ocean Territory 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 British Indian Ocean Territory, 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."
