Best Connect eSIM does not provide a phone number or SMS capability for Australia; only data‑only eSIM plans are offered. Travelers with this plan can access the internet on 4G or 5G networks, but they cannot receive or send regular SMS messages or make traditional voice calls.
For communication, popular VoIP apps such as WhatsApp, Telegram, and iMessage can generally be used over the data connection. However, some destinations may block or restrict certain apps or VoIP services, so travelers should verify that the apps they rely on are accessible in Australia before purchasing a Best Connect eSIM.
