GigSky does not provide eSIM plans for Belize that include a phone number or SMS capability. Travelers can only obtain data‑only eSIMs from this provider in Belize. For voice and messaging, users can rely on VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, though some destinations may restrict access to certain apps, so it is advisable to verify availability of the services you need before purchasing.
