Why do you receive an emergency stop message?

Monthly 1-2 is the billing cycle, during which the system will review the telephone bill data used by users last month. In order to ensure the accuracy of billing data, the phone bill inquiry service is not provided on June 5438+0 and 2, but the system is still operating normally. Users with low balance of available telephone charges will automatically send short messages of downtime warning. If you receive a short message, for your convenience, I suggest you recharge or pay as soon as possible. (The above content is only applicable to Guangdong Unicom users)
