eSimfly does not provide any Cuba eSIM that includes a phone number or SMS service. All eSimfly plans for Cuba are data‑only and do not support traditional voice or text messaging.
Travelers can still make calls and send messages using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations block or restrict certain apps, so it is advisable to confirm that the services you rely on are accessible in Cuba before purchasing a plan.
