When selecting a Japanese SIM card plan, consider your data usage habits, trip duration, and the type of activities planned. Plans typically offer various data volumes (e.g., 5GB, 8GB, 15GB, 20GB).

The SIM card then typically activates automatically upon insertion into your phone, requiring no registration.
