Simbye does not provide an eSIM for Saint Kitts and Nevis that includes a local phone number or SMS capability. The available Simbye plans for this destination are data‑only; they do not support telephony or text messaging.
Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages. However, some destinations may block or restrict access to these services, so it is advisable to confirm that the apps you rely on work in Saint Kitts and Nevis before purchasing a Simbye plan.
