This revolutionary technology allows users to switch carriers or plans without needing to replace any physical SIM cards.
This feature is particularly useful for tourists who prefer not to deal with the hassle of changing SIM cards every time they reach a new destination. With eSIMs, all you need is a QR code provided by your carrier and a compatible device to get connected.

- Convenience: Tourists can easily switch between different networks based on coverage and pricing without needing to find and physically swap out SIM cards.
- Flexibility: An eSIM allows for multiple profiles, enabling users to have both a local plan and their home plan active at the same time, facilitating seamless communication.
- Environmentally Friendly: Since eSIMs eliminate the need for plastic cards, they contribute to reducing electronic waste, making them a greener option.
- Easy to Activate esim in Japan: Yes it is easy, you just buy a suitable esim plan for your Trip in Japan, get QR code via email, and take 3-5 minutes to complete installation.
