Is there a charge for opening mobile phone credit?

According to consulting China Mobile's online customer service, credit start-up means that when the calling party stops one-way due to arrears, the customer can directly apply for credit start-up, and there is no need to pay the phone bill for the time being, and the customer only needs to pay the phone bill before two-way stop. It is a service to help users keep their mobile phones on when they are in arrears or have insufficient balance.

In other words, there is no extra charge for the credit start-up service, and users only need to make up the credit line within the specified repayment period.
