Before travel, download offline maps, key bookings, music/podcasts and any documents you need while on trusted home Wi-Fi. 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
- Data use varies by phone, apps, signal and habits, so treat any GB range as a planning guide rather than a promise.
- Do not assume a daily reset time or uncapped use after a daily high-speed allowance.
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.
