Giga.Tel does not offer an Oceania eSIM with a phone number or SMS capability; the provider only supplies data‑only plans for travelers. To make voice and text calls, users will need to rely on Internet‑based communication.
Most VoIP applications such as WhatsApp, Telegram, and iMessage work over the data connection, but some destinations in Oceania may block or restrict particular apps or VoIP services. Travelers should verify that the services they need are available in their specific destination before purchasing an eSIM from Giga.Tel.
