yaySIM does not offer any eSIM plans for Barbados that include a phone number or SMS capability. The plans available from this provider for Barbados are data‑only, so travelers will not receive an active local number for voice or text services.
Without a local phone number, travelers can still communicate by using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to certain apps, so it is advisable to confirm that the messaging services you rely on are available in Barbados before purchasing a plan.
