No. These are DATA-ONLY plans. You can still call and message over Zalo, LINE, WhatsApp, Messenger, FaceTime — you just won't have a Japanese number for restaurant bookings or services that require a domestic one.

The QR code is emailed as soon as payment clears. If you don't see it, check your spam folder before messaging us.

At home, while you still have Wi-Fi. Scanning needs internet — if you land in Japan without installing, you have no connection to fetch the profile. Installing early costs no data; the plan starts counting only when your phone connects to a Japanese network.

Before you install the QR code, you can cancel for a refund. Once installed, no refund is possible — the profile has been issued to your device and cannot be taken back. This is exactly why you should check device compatibility BEFORE buying.
