Why Your Travel eSIM May Need Data Roaming On

Use the phone menus one check at a time

Mark an item when you have personally checked it. Ticks do not change your phone, account or eSIM settings.

Step 1After landing, use airport Wi-Fi only after you can sign in and open a normal webpage. If that does not work, use hotel Wi-Fi or another steady trusted connection. Then install the eSIM and select it for mobile data. Step 2Read the setup email's roaming instruction for that order. If it says roaming is required, follow that instruction for the travel eSIM. On Galaxy, stop and ask support if the available roaming control does not clearly identify the line. Step 3Check the Australian line separately and leave its Data Roaming off unless the traveller intentionally bought home-carrier roaming. Step 4Wait a moment after the setting change, toggle Aeroplane Mode once if needed, and keep the eSIM installed if service does not appear.

The setting change that matters most

After landing, use airport Wi-Fi only after you can sign in and open a normal webpage. If that does not work, use hotel Wi-Fi or another steady trusted connection. Then install the eSIM and select it for mobile data. A travel eSIM and your Australian SIM can have different jobs, so check the data line, roaming setting and automatic switching separately instead of assuming one change controls all three.

Set the travel line for data on your phone

Choose your phone

iPhone

Open Settings > Mobile Service, Cellular or Mobile Data. Choose Mobile Data, select the travel eSIM, then open that travel line’s options only if the order email says it needs Data Roaming. Keep the Australian line’s Data Roaming off unless you deliberately use home-carrier roaming.

Samsung Galaxy

Open Settings > Connections > SIM card manager. Under Primary SIM or Preferred SIM card, select the travel eSIM for mobile data and switch Auto data switching off unless support says otherwise. The roaming control can vary by Galaxy model, so use it only when the order email identifies the travel line.

Google Pixel

Open Settings > Network & internet > SIMs. Under Your primary SIMs, choose the travel eSIM for Mobile data and keep Automatic data switching off unless support has advised otherwise. Follow the order email for the travel line’s roaming setting.

Other Android

Search Settings for SIM, mobile network or mobile data. Select the travel eSIM for data, keep automatic data switching off if the phone offers it, and use only the roaming or APN instructions supplied for your own order.

Pause here and confirm the line selection

If the step above does not work as expected, stop here. Keep a cropped screenshot of the setting or error, then contact us before changing other settings. Do not include QR or activation details unless we ask.

Keep these cost and line-selection boundaries in place

Whether a travel eSIM needs Data Roaming depends on its own instructions. Follow the order email for the plan you receive.
Do not use an APN as the first response to a roaming question.

What to send before changing another setting

Send the order number, phone model and the exact menu label you can see to hello@thesimshop.com.au, plus a redacted screenshot if possible. That is enough to identify the correct device branch without exposing setup credentials.
