Will I have internet coverage on high-speed trains in Asia?

Traveling by high-speed rail across Asia, such as Japan's Shinkansen or China's CRH trains, is an incredible experience. With EastESIM, you can expect excellent internet coverage for most of your journey. Our eSIMs connect to premium local networks (like Docomo in Japan or China Mobile in China) that typically have robust infrastructure along major rail corridors. While there might be brief signal drops in tunnels or very remote stretches, you'll generally enjoy consistent 4G/5G connectivity, allowing you to stream, work, or share your travel updates as you speed through breathtaking landscapes.
