Voyasim does not currently sell an eSIM for Saint Lucia that includes a phone number or SMS service. Only data‑only plans are available from the provider.
Travelers wishing to make voice calls or send messages can use data‑basing VoIP applications such as WhatsApp, Telegram or iMessage on the Saint Lucia data connection. However, some destinations block or limit certain apps, so users should confirm that the services they rely on are accessible in Saint Lucia before purchasing.
