Benefits of Using eSIM in Japan
Convenience and Instant Activation
One of the biggest advantages of using an eSIM in Japan is the convenience it offers.

Multiple Network Options
Japan has a robust mobile network infrastructure with extensive 4G and 5G coverage. eSIM technology allows you to connect to multiple networks, ensuring you get the best coverage and speed, no matter where you are in the country.
How to Set Up an eSIM in Japan
Step 1: Check Device Compatibility
Before purchasing an eSIM, ensure your smartphone or tablet supports eSIM functionality. Most modern devices, including iPhones from the XR and later models, Samsung Galaxy S20 and newer, and Google Pixel devices, support eSIM technology. Check your device settings to confirm eSIM compatibility.
Step 2: Purchase an eSIM Plan

Step 3: Scan the QR Code
Once you purchase an eSIM plan, the provider will send you a QR code. Simply scan the QR code using your device’s settings, and your eSIM profile will be installed instantly. Some providers also offer manual installation options if QR scanning is not available.
Step 4: Activate the eSIM
After installation, activate the eSIM by selecting it as your preferred mobile network. You can easily switch between your primary SIM and eSIM if your device supports dual-SIM functionality.
