GulfData does not provide an eSIM for Oceania that includes a phone number or SMS capability. Only data‑only eSIM plans are offered for that region.
Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages. However, some destinations may restrict certain apps or services, so it is advisable to confirm that the apps you rely on work in Oceania before purchasing.
