What is the overdraft balance of mobile phone charges? What's the role?

The word "overdraft balance" is not a technical term, but "credit" or "credit line", which means that operators provide users with a certain amount, and if users fail to pay the fees, they will not stop working within this amount.

Its function is to realize that users use it first and then pay, so that users can better enjoy communication services. It will be dynamically adjusted according to users' payment, downtime and consumption quota.
