About connectivity in Antigua and Barbuda
Antigua and Barbuda uses 230V/60Hz with Type A and Type B outlets — reflecting British colonial-era infrastructure with American adaptations. The phone jack is RJ-11. Flow Antigua (Liberty Latin America) and Digicel Antigua operate the country's telecom infrastructure.
Antiguan commercial Internet emerged in the late 1990s through Cable & Wireless. Mobile data dominates current access.
The Antiguan prepaid international calling-card market through the 2000s served the modest outbound diaspora — concentrated in the United States (particularly Brooklyn and Miami) and the United Kingdom.
Tempest Telecom served Antigua and Barbuda through dial-up POPs in St. John's. The Caribbean maritime industry and Barbuda's post-2017 Hurricane Irma reconstruction generated Iridium customer demand.
Modern Antigua and Barbuda has expanding 4G LTE coverage with FTTH concentrated in St. John's.
Tempest's services across Antigua and Barbuda, 1997–2012
Tempest Telecommunications operated international connectivity services in Antigua and Barbuda between 1997 and 2012 under a unified prepaid account that absorbed multiple service types onto a single customer credential. Customers in Antigua and Barbuda drew from the same balance for pre-paid international voice calling, RADIUS-authenticated dial-up Internet roaming, metered Wi-Fi hotspot access, Iridium satellite voice, and Inmarsat BGAN data terminals. An attempted kiosk-payment federation (PATN, 1998) extended the same architecture to public Internet terminals but failed to reach scale.
Iridium satellite voice was available in Antigua and Barbuda from approximately 2001 (post-bankruptcy relaunch). Thuraya coverage did not extend to Antigua and Barbuda; Inmarsat BGAN data terminals filled the broadband gap from late 2005.
