FullBars does not provide an eSIM for Antigua and Barbuda that comes with a local phone number or the ability to send SMS. The only eSIM plans available from this provider for the destination are data‑only options. Travelers who need messaging or voice can typically use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but they should check that the apps they rely on are accessible in Antigua and Barbuda before purchasing, as some destinations may restrict specific VoIP services.
