How to Set Up Ubigi in Japan

Ubigi uses QR code activation. Follow these steps to get connected.

  1. 1

    Purchase your plan

    Visit the Ubigi website or app and select your preferred data plan for Japan. Complete the checkout process.

  2. 2

    Receive your QR code

    After payment, Ubigi will send you a QR code via email or display it in the app. This code contains your eSIM profile.

  3. 3

    Scan the QR code

    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.

  4. 4

    Label your eSIM

    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.

  5. 5

    Activate in Japan

    When you arrive, enable the eSIM data line in your cellular settings. Your phone will connect to SoftBank automatically. The plan validity begins at first connection.

Tips for Using Ubigi in Japan

Install before you fly

Download the Ubigi eSIM profile while you are on WiFi at home. This ensures everything is ready when you land in Japan.

Verify network selection

After activation, check that your phone is connected to SoftBank. Go to Settings > Cellular > Network Selection and verify the network name.

Enable data roaming

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.

Contact support if needed

Ubigi 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.
