Restrictions on the volume of data traffic may apply. We provide adequate data capacity for general use, but a communication restriction can be applied to users who communicate in large quantities, download files continuously, long videos, etc. In these cases, measures without prior notice can be taken, such as interrupting communication or slowing down greatly. Customers who consume large amounts of data need to pay attention to this, as per the information above. The speed of data transmission during use can vary significantly due to the user's environment (such as the specifications of the terminal device) and network congestion. * There will be no refund if suspension measures or speed restrictions are applied by the operator or the government.
