BIC SIM Launches Unlimited Data, 5G-Ready Prepaid SIM 'Japan Travel SIM Unlimited for BIC SIM' at Bic Camera Group for International Visitors

As the number of international visitors to Japan continues to grow, mobile data usage during their stay has become increasingly diverse.

This service operates on au's 5G and 4G LTE networks across Japan. After purchase, users can simply insert the SIM into their device and begin using it immediately—no web registration or additional setup required. This makes it ideal not only for immediate use upon arrival but also for travelers who have exhausted their pre-arranged data plans mid-trip.
