MobiMatter does not offer Australian eSIM plans that include a local phone number or SMS capability. Their Australian plans are purely data‑only, so travelers will not receive a traditional mobile number for voice calls or text messaging. To communicate over the network, users can rely on VoIP applications such as WhatsApp, Telegram, or iMessage that use the data connection; however, the availability of these services can vary by destination, so it is advisable to verify that the apps you need are accessible in Australia before placing an order.
