Chapter 1: Communications

Article 1 (Communication Area)

1. The communication area for mobile communication services will be the same as the communication area of the partner operators.Communication through the contracted line is limited to when the terminal equipment connected to the contracted line is within the communication area. However, even within the communication area, communication may not be possible in places where radio wave propagation is difficult, such as indoors, underground parking lots, building shadows, tunnels, mountainous areas, etc.
2. In such cases, the user of the contract cannot claim any damages from our company due to the inability to use mobile communication services, except in cases attributable to our company.

Article 2 (Restrictions on Communication Use)

1. Our company may temporarily restrict communication through the contracted line in cases where it is technically, for maintenance, or otherwise necessary related to the contracted line, or if restrictions on the use of the contracted line are imposed by the partner operators based on the telecommunications service agreements provided by the partner operators or interconnection agreements or other contracts concluded with our company.
2. In such cases, the user of the contract cannot claim any damages from our company due to the restriction of communication, except in cases attributable to our company.

Article 3 (Restrictions on Communication Time, etc.)

1. In addition to the cases specified in the preceding article, our company may restrict communication time or the use of communication in specific areas when communication is extremely busy.
2. In such cases, if a natural disaster, incident, or other emergency occurs or is likely to occur, it may be necessary to prioritize communications related to disaster prevention or relief, ensuring traffic, communications, or power supply, or maintaining order. For this purpose, communications using mobile wireless devices used by organizations designated by the Minister of Internal Affairs and Communications through public notice under the Telecommunications Business Act Enforcement Rules (excluding devices confirmed through consultation with our company or partner operators) may be stopped (including stopping communications on contracted lines in specific areas).
3. In the communications mentioned in paragraph 1, if the connection time exceeds a certain time or the non-communication time exceeds a certain time, our company may disconnect the communication.
4. Our company may restrict the speed and amount of communication for dynamic video playback or file exchange (applications, etc., involving continuous and large bandwidth-consuming communication procedures) to provide mobile communication services smoothly.
5. Our company may collect, analyze, and store communication-related information to implement the communication time and other restrictions specified in this article.

Chapter 2: Damages, etc.

Article 4 (Damages Due to Inability to Use)

1. If our company fails to provide the mobile communication service due to our fault and the mobile communication service is completely unusable (including cases where communication on the contracted line related to the contract is significantly obstructed, equivalent to a completely unusable state. The same applies hereinafter in this article) for more than 24 hours continuously, we will compensate the user for the damage.
2. In such cases, our company will calculate the time during which the mobile communication service is completely unusable continuously from the moment we confirm it (limited to multiples of 24 hours) in days and compensate the amount corresponding to the total amount calculated based on the charges specified in the fee table for the number of days as the damage incurred, limited to that amount.
3. In such cases, when calculating the amount of damages corresponding to the number of days, if there is a fraction less than 60 sen in the communication fee calculation, that fraction will be discarded. If there is a fraction of 60 sen or more, it will be rounded up. Handling of fractions in daily prorated calculations and discounts will be done according to a method separately determined by us.
4. In the case specified in paragraph 1, if our company fails to provide the mobile communication service due to intentional or gross negligence, the provisions of paragraphs 2 and 3 of this article will not apply.

Article 5 (Damages Arising from Use)

1. Our company is not responsible for any damage caused by the destruction, loss, or disclosure to third parties of information, etc., generated while using the mobile communication service, or damage caused by information, etc., obtained, except in cases of intentional or gross negligence on our part.
2. Our company is not responsible for any damage caused to the user by the mobile communication service, except in cases of intentional or gross negligence on our part.
3. If the user causes damage to a third party while using the mobile communication service, the user shall resolve it at their own responsibility and expense and shall not cause any damage to our company or make any claims against our company.
4. If the user causes damage to our company due to intentional or negligent acts, our company may claim compensation from the user for the amount equivalent to the damage incurred.

Article 6 (Contract with Partner Operators)

The user agrees that when using the mobile communication service, they will enter into a connection agreement with the partner operators and that this connection agreement may be terminated when they cease to use the mobile communication service.
