To learn how to use an eSIM in Australia, separate installation from day-to-day line management. Install before departure, then assign the eSIM to mobile data after arrival while keeping the home line under deliberate control.
The important settings are the active data line, data switching, roaming instruction and network selection. Menu labels vary by phone.
NoveSIM travel eSIMs are data-only, without an Australian number or conventional calls and SMS. WhatsApp, maps and internet calls use the data connection.
Quick answer: Enable the Australia eSIM, select it for mobile data, disable automatic data switching and follow the plan’s roaming instruction. Keep your home SIM only for calls or verification messages if needed.

For installation rather than daily use, follow how to install an Australia eSIM.
Keep the home SIM without accidental data use
A dual-SIM phone can retain the home number for calls and SMS while the eSIM supplies data. Calls, voicemail and messages may still incur home-carrier roaming charges. Review Australia roaming charges before leaving both lines active.
Use apps, hotspot and 5G realistically
Messaging and internet calling work through data. Hotspot and 5G availability depend on the plan, device, partner network, region and local coverage. Confirm tethering before relying on a laptop connection.
Correct APN and connection problems
If manual NoveSIM APN entry is required, use data.esim. Toggle flight mode, restart and recheck the selected line. Do not delete the installed eSIM unless support instructs you. Use Australia eSIM troubleshooting for the full sequence.

FAQ
Should data roaming be on?
Follow the specific plan instruction; many travel eSIMs require it because they connect through partner networks.
Can I receive SMS on my normal number?
Often yes with dual SIM, but the home carrier’s roaming terms still apply.
Why is the home SIM using data?
Automatic data switching may be enabled. Turn it off and reselect the Australia eSIM for mobile data.

No. Keep it installed, check settings and contact support before deletion.
Final Recommendation
To understand how to use an eSIM in Australia, focus on deliberate dual-SIM and mobile-data settings after installation.
Select the travel line, use data.esim where required and prevent automatic switching to the home SIM.
Keep the eSIM installed while resolving any connection problem.
