Telecom Square Inc. (Headquarters: Chiyoda-ku, Tokyo, CEO: Yuji Yoshitake, hereafter 'the Company'), which provides cross-border mobile communication solutions globally, announces the details of its battery safety measures and operational policies for its self-service Wi-Fi rental 'WiFiBOX', in response to the tightening of regulations on bringing mobile batteries onto airplanes.
In recent years, smoke and fire incidents caused by lithium-ion batteries have been increasing globally. In response, the International Civil Aviation Organization (ICAO) adopted an international standard in March 2026, restricting the number of mobile batteries allowed on board to "up to 2 per passenger." In Japan, the Ministry of Land, Infrastructure, Transport and Tourism is preparing to introduce similar standards, which are expected to be applied from mid-April 2026 onwards.
Amidst this trend of stricter regulations, there is growing concern regarding the safety of all electronic devices with built-in batteries, and user anxiety regarding "carry-on eligibility" and "safety" is increasing. Given this situation, we are publicly announcing the specific initiatives for battery safety measures we have advanced for WiFiBOX.
## Battery Safety Measures and Main Initiatives for WiFiBOX
While WiFiBOX is a communication device, it is a product with a built-in battery. Acknowledging these product characteristics, the Company strives to ensure safety from the perspectives of design, quality, and operation.
1. Providing Customers with Safe Usage Instructions
We have published a "Quick Guide for Safe Use" on the official WiFiBOX website, summarizing correct usage methods and precautions, to ensure widespread awareness. Because proper use ensures the safety not only of the current user but also the next customer, we continuously disseminate this information.

2. Product Design Compliant with Safety Standards
WiFiBOX terminals comply with the PSE mark display requirements based on Japan's Electrical Appliance and Material Safety Act. Furthermore, the embedded lithium polymer batteries utilize cells that comply with international safety standards such as UL, CB, and CCC. They also feature the following protective functions:
- Overcharge prevention
- Over-discharge prevention
- Overcurrent prevention
- Short circuit prevention
The design automatically cuts off the circuit if an abnormality is detected, aiming to reduce the risk of heat generation or fire.
*UL: US safety standard
*CB: International electrical equipment safety standard
*CCC: China Compulsory Certification
