My mobile phone is in arrears, why can I make a phone call? The monthly rent is not enough. There is a message saying that 4 yuan is the rest of my IOUs account. What is a white account?

Due to the business billing and business adjustment at the beginning of the month, some customers who forgot to recharge in time stopped working and delayed things. General telecom companies will give you a certain amount of allowable arrears according to your previous consumption and recharge. Without arrears, you won't stop working immediately, and you don't have to pay in the business hall at the beginning of the month.

Of course, when the allowable amount of arrears given to you is used up, it will stop, and you must recharge it before you can continue to use it. The balance after recharging is the amount after deducting the arrears.
