This technology not only saves space in devices but also allows users to switch between different telecom providers more flexibly. Whether you want to change plans or need temporary internet access, eSIMs offer a faster and more convenient way to switch.

Steps for Using eSIM in Japan

Using an eSIM is very simple. Follow these steps to set it up:

Check Device Compatibility with eSIM:
Not all phones support eSIM. Currently, eSIM is supported by brands like iPhone (XS, XR, and newer models), Google Pixel, some Samsung devices, and other Android phones. Before purchasing an eSIM, make sure your phone supports it.
If you’re unsure whether your phone supports eSIM, you can dial *#06# on your phone. If you see "EID" or "ICCID," it means your phone is eSIM-compatible.
Choose an eSIM Plan: Select the appropriate data plan based on your trip's duration and your internet usage needs. Most providers offer options such as short-term data plans, daily data plans, or monthly subscriptions.
Download and Activate the eSIM: After purchasing your eSIM plan, you will receive a QR code or installation link. Open your phone’s settings, go to the Mobile Network or Cellular Plans section, and scan the QR code to download and activate your eSIM.
Set Network Preferences: To avoid roaming charges, it is recommended to temporarily disable your primary SIM card once the eSIM is activated. Ensure that your eSIM is connected to a local network provider in Japan, and you’re all set to use it.
