Zwitchy does not provide a Cuba eSIM plan that includes a phone number or SMS capability. The provider only offers data‑only eSIMs for Cuba, so travelers cannot receive or send text messages, nor can they place regular voice calls without using a separate phone number. They can still use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages, but availability may vary depending on local restrictions, so travelers should confirm that the apps they rely on are accessible in Cuba before purchasing a Zwitchy eSIM.
