eSIM for Antigua and Barbuda — Instant 4G/5G Data Plans

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.

Install your MobiSIM eSIM before your flight so you are connected as soon as you land at V.C. Bird International Airport in Antigua. Download offline maps for St. John's, English Harbour, and Barbuda before travelling, particularly if you plan to explore more remote beaches and coastal areas. Keep your home SIM active for calls while MobiSIM provides data throughout your stay. If you are travelling to Barbuda by ferry or small aircraft from Antigua, download any essential navigation and accommodation information before you depart, as connectivity on Barbuda can be less reliable. Antigua Sailing Week and other major events bring high visitor numbers, so having your data plan set up in advance avoids any delays at the airport or port.
