Superalink does not offer an Australian eSIM plan that includes a local phone number or SMS capability. All of its eSIM offerings for Australia are data‑only, meaning travelers will receive high‑speed internet but will not be able to send or receive traditional SMS or make telephone calls with a local number.
Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but they should confirm that those services are accessible in Australia before purchasing a plan, as some destinations may block or restrict specific apps.
