How do I know if my phone will work with an eSIM for Japan?

To use an eSIM in Japan, your phone must be both carrier-unlocked and eSIM-compatible. Most flagship smartphones released since 2018—such as iPhone XS and newer, Google Pixel 3 and newer, and many Samsung Galaxy S and Z series models—support eSIM. The easiest way to check is to look in your phone settings for an option like “Add eSIM” or “Add mobile plan.” You can also consult EasyAlo’s compatibility list before purchasing to confirm your specific model is supported.
