Why do you repeatedly receive the message of "insufficient balance"?

If you repeatedly receive the warning message of "insufficient balance", the possible situation is as follows: 1. Our company will remind users with insufficient account balance to prevent users from stopping because of insufficient phone bills, which will affect their normal use. It is recommended that you pay in time; 2. If you have paid the phone bill but still receive the early warning message, it may be sent by mistake, please ignore it; 3. If you receive multiple repeated warning messages at the same time, I'm sorry for the inconvenience. This situation may be a fault, so it is recommended that you contact the manual customer service for handling. (The above content is only applicable to Guangdong Unicom users)
