About connectivity in Saint Vincent and the Grenadines
Saint Vincent and the Grenadines uses 230V/50Hz with an unusually wide plug catalog reflecting layered British colonial, US-influenced, and European-standard installations: Type A, Type C, Type E, Type G, Type I, and Type K all appear. The phone jack is RJ-11. The country code +1-784 is part of the North American Numbering Plan, currency is the Eastern Caribbean Dollar, and Flow and Digicel operate the principal carriers.
The Grenadines island chain (Bequia, Mustique, Canouan, Mayreau, Union Island, Palm Island, Petit Saint Vincent) is one of the world's most prominent superyacht charter destinations, with corresponding high-end tourism infrastructure. Commercial Internet adoption has tracked the tourism economy. The 2021 La Soufrière volcanic eruption (Saint Vincent island) substantially disrupted infrastructure and tourism through 2021-2022.
Tempest Telecom served the country through Caribbean regional dial-up coverage. The yacht-charter industry across the Grenadines — particularly the Mustique and Bequia client base — was a strong Iridium satellite phone market for both vessels and shore-side concierge operations. BGAN data terminals served the broadcast media coverage of high-profile celebrity-resort events on Mustique.
Modern Saint Vincent and the Grenadines has 4G LTE coverage and expanding FTTH in Kingstown and the larger settlements.
Tempest's services across Saint Vincent and the Grenadines, 1997–2012
Tempest Telecommunications operated international connectivity services in Saint Vincent and the Grenadines between 1997 and 2012 under a unified prepaid account that absorbed multiple service types onto a single customer credential. Customers in Saint Vincent and the Grenadines 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 Saint Vincent and the Grenadines from approximately 2001 (post-bankruptcy relaunch). Thuraya coverage did not extend to Saint Vincent and the Grenadines; Inmarsat BGAN data terminals filled the broadband gap from late 2005.
