MTX Connect does not provide an Australian eSIM that includes a local phone number or SMS capability. Travelers who purchase an MTX Connect eSIM for Australia will receive only high‑speed data without inbound or outbound voice or text services. If a phone number or SMS is required, consider using popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but be aware that some destinations may block or restrict access to certain apps or VoIP services, so it is advisable to verify that the apps you rely on are functional in Australia before buying the plan.
