IIJ Launches Unlimited Data, 5G-Compatible Prepaid SIM 'Japan Travel SIM Unlimited for BIC SIM' at Bic Camera Group Stores for Foreign Visitors

IIJ announces the launch of 'Japan Travel SIM Unlimited for BIC SIM,' a prepaid SIM card with unlimited data and 5G support, designed for foreign visitors and temporary returnees. Sales will begin on June 17, 2026, at Bic Camera Group stores (Bic Camera, Kojima, Sofmap) nationwide and through their online shops.

As the number of inbound tourists continues to grow, mobile data usage in Japan has become increasingly diverse. Demand is rising for high-speed, stable connectivity without data limits—especially for video streaming, online meetings, and app usage. In response, IIJ is expanding its existing 'Japan Travel SIM' lineup by introducing this new unlimited data option.

The 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 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.

(※) APN settings may be required on certain devices. (※) This service is data-only. Voice calling and SMS functions are not available.
