There is a charge for short messages.

According to your description, if you have paid the electricity bill, you can check the payment record and verify the situation through channels such as "China Southern Power Grid 95598" WeChat WeChat official account. If you still receive the reminder message or still display the arrears, the following situations will cause this problem:

1. Electricity fee reminder messages are sent by the system in batches. If there is congestion in sms channel, reception will be delayed; 2. Your payment information has not been returned to the power supply system, so it cannot be written off. In the meantime, the power supply enterprise has been urging you to pay the fee. Please forgive the inconvenience.

It is suggested that you can call the 24-hour service hotline 95598 for consultation.

I hope our answer is helpful to you.
