      "question": "How many digits does a phone number in Montserrat have?",
      "answer": "Mobile numbers have 10 national digits (7 when dialled locally). Fixed line numbers have 10 national digits (7 when dialled locally). That is the national number, without the country code +1 and without the trunk prefix 1."
    },
    {
      "question": "What is the country code for Montserrat?",
      "answer": "+1. From abroad, dial your own exit code, then 1, then the national number without its trunk prefix 1. From inside Montserrat, the exit code for international calls is 011."
    },
    {
      "question": "Which prefixes are mobile numbers in Montserrat?",
      "answer": "Mobile numbers in Montserrat use area code 664 and 12 of its central office codes (the three digits after the area code), such as 349, 396, 496; the mobile regular expression on this page lists them all (example: (664) 492-3456). Dialled within the North American Numbering Plan, every number reads alike: 1, the area code, then seven digits."
    },
    {
      "question": "Can a mobile number in Montserrat be ported to another carrier?",
      "answer": "Yes. Montserrat has mobile number portability, so a prefix tells you the carrier a number was originally allocated to, not necessarily the one serving it today. Only a live carrier lookup (an HLR or MNP query) answers that."
