Key Features at a Glance

Why Get This eSIM?

• Pure Unlimited Data Without Restrictions: Unlike standard travel plans that enforce strict daily caps or throttle speeds after a few gigabytes, this eSIM offers truly unrestricted internet access. Stream, upload, and browse continuously for 8 full days without worrying about running out of high-speed data.
• Direct KDDI Local Network Access: By connecting directly to KDDI—one of Japan’s premier telecom giants—you enjoy superior coverage and signal stability. Experience seamless high-speed internet whether you are riding the Shinkansen bullet train, visiting historic Kyoto temples, or navigating Tokyo's dense urban centers.
• Blazing Fast Speeds Up to 1 Gbps: Powered by high-bandwidth local infrastructure, this eSIM delivers speeds reaching up to 1 Gbps. Enjoy buffer-free high-definition video streaming, instant route calculations, rapid app downloads, and uninterrupted video calls across your entire itinerary.
• Generous 7GB Hotspot Sharing: Keep your secondary devices connected or share high-speed internet with travel companions. The plan includes a dedicated 7GB tethering allowance, making it ideal for connecting laptops, tablets, or extra phones while working or exploring on the road.
• Flexible 180-Day Pre-Purchase Window: Plan your itinerary stress-free. The provided QR code remains valid for 180 days after purchase, allowing you to secure your high-speed connectivity months in advance and activate it immediately upon landing at Japanese airports.

How to Install the eSIM in 5 Simple Steps

1. Verify Phone Compatibility and Connectivity: Ensure your smartphone is carrier-unlocked and eSIM-compatible, then connect your device to a stable Wi-Fi network before initiating installation.
2. Scan the Activation QR Code: Open your phone’s settings menu, navigate to Cellular/Mobile Data options, select "Add eSIM" or "Add Cellular Plan," and scan the QR code received after purchase.
3. Label Your Travel Cellular Profile: Assign a clear, custom label to the new profile (such as "Japan eSIM") to easily distinguish it from your primary personal SIM line.
4. Turn On Data Roaming for the eSIM: Set your newly installed travel eSIM as your designated primary cellular data source and toggle "Data Roaming" to ON for that line.
5. Connect to KDDI Network Upon Arrival: When you arrive in Japan, disable airplane mode; your phone will automatically register on the local KDDI network and initiate your 8-day service.
