Kolet does not provide an eSIM for Saint Lucia that includes a phone number or SMS capabilities. Users can purchase only data‑only plans from Kolet when traveling to Saint Lucia, meaning the eSIM will not support inbound or outbound voice calls or SMS text messages. Travelers who need messaging and calling services can generally use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain VoIP services, so users should verify that the apps they rely on are accessible in Saint Lucia before purchasing a Kolet plan.
