    {
      "question": "What is the country code for Guernsey?",

    },
    {
      "question": "Which prefixes are mobile numbers in Guernsey?",
      "answer": "Mobile numbers start with 077, 078 or 079 in national form; the mobile regular expression on this page gives the exact ranges (example: 07781 123456). The carrier table shows which prefix blocks were allocated to which operator."
    },
    {
      "question": "Can a mobile number in Guernsey be ported to another carrier?",
      "answer": "Not on record. The plan data this page is built from does not list mobile number portability for Guernsey, 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."
