Bordersim currently does not provide an eSIM plan for Australia that includes a phone number or SMS capability. All eSIM offers from Bordersim for Australian travellers are data‑only, meaning you can use internet services but cannot make traditional voice calls or send or receive SMS messages on a local Australian phone number.
Travelers who need to stay in touch can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, it is advisable to verify that these apps are accessible in Australia before purchasing, as some destinations may block or restrict specific VoIP services.
