The cheapest and most convenient way to use your mobile phone overseas is to buy a prepaid digital eSIM online before you travel.

Just ensure your phone is unlocked and eSIM-compatible before you start.
What is an e-sim?
An eSIM (embedded SIM) is a digital SIM technology that eliminates the need for a physical SIM card. Built directly into your smartphone or other compatible devices, eSIMs allow you to activate a mobile data plan instantly by scanning a QR code or downloading a profile.
Unlike traditional SIM cards, eSIMs don’t require you to swap out your current card or fiddle with small trays. You can also store multiple eSIM profiles on a single device, making them an excellent choice for frequent travelers or those looking to maintain both local and international connectivity.
You can keep your Australian phone number while using an eSIM.
The popularity of eSIMs in Japan has surged, offering travelers a more seamless way to stay connected, especially in regions where WiFi coverage remains unreliable.
