GigSky does not provide any eSIM plan for Dominica that includes a local phone number or SMS capability. Travelers can only purchase data‑only plans for the island.
If a traveler needs voice or messaging services, they will normally rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, access to these services may be restricted in some destinations, so it is advisable to confirm that the apps they intend to use are available in Dominica before buying a plan.
