How much will it cost for your trip?
Kingstown (Saint Vincent) and main coastal roads have good 4G. Bequia (Port Elizabeth) has reasonable coverage. Mustique has basic signal at the main village. The Tobago Cays (uninhabited national marine park, filming location for Pirates of the Caribbean) have no mobile coverage. Mayreau, Union Island and Canouan have basic coverage in main towns.
The Tobago Cays are one of the Caribbean's most beautiful anchorages — uninhabited, pristine coral reefs, sea turtles. No mobile coverage. Download offline marine charts (Navionics or C-Map), anchorage guides and tide tables in Bequia before heading south. La Soufrière volcano (1,234m) is accessible by trail — coverage is absent above the lower forest.

eSIM — Saint Vincent And Grenadines
Network coverage in Saint Vincent and the Grenadines
Saint Vincent and the Grenadines has two mobile operators: Digicel (market leader, ~98% population coverage) and Flow (the incumbent). Both run 4G/LTE across mainland Saint Vincent and the inhabited Grenadines; 5G is not commercially available. Coverage is not uniform: Flow tends to have the edge around Kingstown and the Villa/Indian Bay tourist strip, while Digicel is often stronger on Bequia and Union Island — which matters if you're island-hopping.
Both networks weaken on the smaller cays (Mayreau and the lesser islands), with dead zones on the windward coast and the La Soufrière interior — locals often carry both SIMs. On this page, Airalo routes via Digicel and Flow; Yesim does not name its local carrier; coverage piggybacks on the same Flow or Digicel towers either way, so verify the specific Grenadine islands on your itinerary before relying on any single plan.

VPN, passwords and documents
On hotel or café Wi-Fi, a VPN can be useful to keep your browsing private from the network operator. A password manager is also worth having for managing account access on the road. A secure cloud backup of your passport, visa and accommodation details can also be useful — keep an offline copy too. None of these are mandatory.
