Is roaming with my home SIM free in Japan compared to EastESIM?

No, roaming with your home SIM in Japan is typically not free and can be quite expensive compared to using an EastESIM. Most international carriers charge significant daily fees or high per-MB rates for data usage outside your home country. An EastESIM for Japan offers a much more cost-effective solution, providing a set amount of high-speed data for a one-time fee. This means you can explore Tokyo's vibrant districts or the serene temples of Kyoto without worrying about unexpected roaming charges, enjoying seamless and affordable connectivity.
