Airalo connects to NTT Docomo in Japan, providing excellent coverage quality. Here is what that means for your experience.
Airalo uses QR code activation. Follow these steps to get connected.
Visit the Airalo website or app and select your preferred data plan for Japan. Complete the checkout process.
After payment, Airalo will send you a QR code via email or display it in the app. This code contains your eSIM profile.
On your phone, go to Settings > Cellular > Add eSIM > Use QR Code. Point your camera at the QR code. The eSIM profile will download in about 30 seconds.
Name your new eSIM line (for example, "Japan Data") so you can easily identify it in your settings. Set it as the primary line for mobile data.
When you arrive, enable the eSIM data line in your cellular settings. Your phone will connect to NTT Docomo automatically. The plan validity begins at first connection.
Download the Airalo eSIM profile while you are on WiFi at home. This ensures everything is ready when you land in Japan.
After activation, check that your phone is connected to NTT Docomo. Go to Settings > Cellular > Network Selection and verify the network name.
Some phones require "Data Roaming" to be enabled for eSIM plans to work abroad. This is safe with an eSIM since you are using a prepaid plan, not your home carrier's roaming.
Airalo offers customer support via their app, email, and live chat. If your eSIM is not connecting in Japan, reach out before troubleshooting on your own.
