My mobile phone card is a mobile two-star user, so I can overdraw the phone bill in 20 yuan. Can I call and send messages online during the overdraft period?

Taking Henan users as an example, China Mobile will provide you with a certain overdraft limit after you use your prepaid phone bill. After the overdraft limit is used up, we will reserve the called call for you for a certain period of time to ensure that you will not interrupt your communication when it is inconvenient to pay. The higher the star rating, the higher the overdraft limit. See the figure below for the overdraft limit of telephone charges that each star can enjoy:

Note: When stopping, stop the caller first. After a single stop or stop for 72 hours (one-way stop), the arrears will reach the overdraft limit. In view of the differences in business regulations among provinces, please consult local 10086 in detail.
