Downtime refers to the suspension of mobile phone service, and users can't use all services such as telephone, SMS and Internet. There are generally two kinds of downtime. One is that the user actively applies to the operator to suspend the mobile phone service by reporting the loss or stopping the phone number. The other is that the communication operator suspends the user's mobile phone service when the user's mobile phone account balance is zero or the given credit line has been consumed.
