Antigua and Barbuda is served by two main mobile operators: Flow and Digicel, both of which provide 4G LTE coverage across Antigua including St. John's, English Harbour, and the main resort and beach areas. Barbuda, the smaller sister island, has more limited infrastructure, and coverage there may be less consistent than on the main island, particularly in areas that are still recovering from hurricane damage in previous years. The waters and remote coastline around both islands may have intermittent signal depending on your distance from shore. MobiSIM connects through supported local networks to deliver reliable mobile data across the main populated and tourist areas of both islands.
