Buyed Saint Lucia eSIM from ZetSIM and activated before my London Gatwick flight and had a local connection at Hewanorra International Airport before the transfer reached the Piton shadows of Soufriere. Affordable start to the Caribbean's most dramatic island.

Diving the Anse Chastanet reef where the coral grows right up to the volcanic sand, a hike to the rim of the drive-in Sulphur Springs as steam rose around our feet, and watching both Pitons turn violet at sunset from a catamaran sailing between them, the Saint Lucia eSIM from ZetSIM was there for every extraordinary Caribbean moment with solid signal throughout the island.

Used ZetPass for the Saint Lucia eSIM at half price. Two weeks on one of the Caribbean's most iconic islands and connectivity throughout. From the Friday night jump-up street party at Gros Islet to the rum distillery tours of Vieux Fort, ZetPass made Saint Lucia even more enjoyable.

Shared the hotspot from my Saint Lucia eSIM on a sailing catamaran between Rodney Bay and the Pitons. Two of us connected for the afternoon sail down the west coast.
