eSIM Not Working in Australia: Complete Troubleshooting Guide

If your eSIM is not working in Australia, do not worry. In most cases, the issue is caused by a phone setting such as Data Roaming, mobile data selection, APN configuration, or automatic SIM switching.

Whether you are in Sydney, Melbourne, Brisbane, Perth, Gold Coast, Cairns, Tasmania, the Whitsundays, or the Great Barrier Reef, these steps can help you get your Australia eSIM connected.

Quick answer: make sure your Australia eSIM is enabled, set it as your mobile data line, turn on Data Roaming for the eSIM, set APN to data.esim if needed, disable automatic data switching, and restart your phone.

Why Your eSIM May Not Work in Australia

Most eSIM connection problems happen because the phone is not using the travel eSIM correctly.

• The eSIM is installed but not enabled.
• Mobile data is still assigned to the primary SIM.
• Data Roaming is turned off for the eSIM.
• The APN is missing or incorrect.
• Automatic data switching is using the wrong SIM.
• The phone has not registered on a local network yet.
• The device is not eSIM compatible or is carrier locked.

Step 1: Make Sure the eSIM Is Installed

First, check that the Australia eSIM profile appears in your phone settings.

On iPhone:

Settings → Cellular

On Android:

Settings → Network & Internet → SIMs

On Samsung:

Settings → Connections → SIM Manager

If the eSIM does not appear, it may not have been installed successfully.

Step 2: Enable the Australia eSIM

Your eSIM must be turned on before it can connect to a network.

• Open your SIM settings.
• Select the Australia eSIM.
• Make sure the line is enabled.
• Wait a few minutes for network registration.

Step 3: Set the eSIM for Mobile Data

This is one of the most common issues.

Your phone may still be using your primary SIM for mobile data instead of the Australia eSIM.

Set:

• Mobile Data: Australia eSIM
• Calls: Primary SIM
• SMS: Primary SIM

Step 4: Turn On Data Roaming for the eSIM

Travel eSIMs usually require Data Roaming to be enabled.

Turn Data Roaming ON for the Australia eSIM.

If you want to avoid roaming charges from your home operator, keep Data Roaming OFF on your primary SIM.

Step 5: Check APN Settings

If your eSIM has signal but no internet, the APN may need to be added manually.

Setting	Value
APN	data.esim
Username	Leave blank
Password	Leave blank

Step 6: Restart Your Phone

After changing eSIM settings, restart your phone.

This helps the device register again on the local Australian network.

Step 7: Toggle Airplane Mode

If the phone still does not connect:

1. Turn Airplane Mode ON.
2. Wait 30 seconds.
3. Turn Airplane Mode OFF.
4. Wait several minutes.
