If you're buying a physical SIM
Use the exact model’s specifications to find the required card size, such as nano-SIM. If the handset has no tray, a physical travel SIM isn’t a way around its eSIM setup. If it does have a tray, check whether inserting the travel card would replace the Australian SIM or use a second supported slot.
Keep any removed home SIM somewhere secure, along with the correct tray tool. Cutting a card or forcing an adapter into the tray isn’t a sensible airport experiment.
If you're buying an eSIM
Use our compatibility checker with the model number and sales region, then confirm that the original carrier has unlocked it. An EID or Add eSIM menu doesn’t establish the full match by itself.
A supported phone may let you keep a physical Australian SIM in place while using a travel eSIM for data, but the permitted combination of active lines depends on the model. Two stored profiles don’t necessarily mean two simultaneously active eSIMs.
The phone number stays with its service
Changing the data line doesn’t transfer the Australian number onto the travel eSIM. Our data-only offers provide internet access for apps, while ordinary calls, texts and the home number remain separate services with their own terms.
Once you’ve chosen a compatible offer, save its setup email before flying and install after landing on working Wi-Fi. Our installation guide walks through that step; if the phone cannot use eSIM, compare a correctly sized physical SIM or a separate Wi-Fi device instead.
