How can there be a sudden power outage? I didn't even get the notice.

Generally speaking, power outages are divided into pre-arranged power outages, fault power outages and arrears power outages. Pre-arranged power outages and overdue power outages will be notified in advance. If you don't receive the notice, your mobile phone number may not be registered with the power supply company to receive power outage information. You can call the 95598 power supply service hotline to register. If there is a power outage, there is no way to notify in advance because it is very sudden. If you are a customer of Guangdong Power Grid, you can pay attention to and bind the public platform of "China Southern Power Grid 95598", click "My Power Consumption" > "Power outage/emergency repair" > "Inquire about other power outage information" > select "Regional Power Supply" > enter "Verification Code" to inquire about power outage information.
