eSIM vs. SIM Card

How does a virtual SIM (another name for an eSIM) plan stack up against its traditional counterpart – physical SIM cards? The comparison leans heavily in favor of eSIMs for numerous reasons.

Advantages of eSIM Over A Physical SIM Card

A Japan eSIM offers more freedom and flexibility compared to a traditional SIM card. With an eSIM Japan travel is easy to manage through the GigSky app (iOS | Play Store). Since it’s a mobile data only plan, calls and SMS through your regular number likely won’t be available. On the upside, this means you don’t need local phone numbers – a significant convenience. 

Traditional carriers or other carriers may boast “unlimited data,” but many of them throttle data speeds after a certain amount is consumed. Additionally, SIM cards often have high upfront costs, and using your home plan abroad can result in hefty roaming fees. 

Customizing eSIM Plans Based on Usage Preferences

The best eSIM for Japan will depend on the duration of your stay, and your specific data requirements. Ensure that your device is dual SIM compatible (you can usually find this in the device settings). Then, look for an eSIM mobile data plan that balances cost and your coverage requirements. 

We have a series of recommendations to help you understand some of these considerations. 

Tips for Choosing the eSIM

Selecting an eSIM for Japan will vary from person to person. To make the most of your digital journey, consider key factors when choosing the right eSIM plan for you.
