Why can I call and send text messages online when my mobile phone card is in arrears?

This is the credit system of China Mobile. The mobile company will provide you with a credit rating according to the usage time and consumption amount. The higher the rating, the higher the overdraft limit. If the overdraft limit is exceeded, the mobile company will stop working. The mobile company will make statistics on the date of 1 1 every month. It is recommended to pay the phone bill before 1 1 to avoid downtime and credit rating decline.

Shenzhouxing can also participate in the credit system. It will take at least one year for Shenzhou Bank to reach the credit rating of 1. After one year, you can overdraw 5 yuan. According to the continuous use and consumption, mobile companies will gradually improve their credit rating. Similarly, if the phone bill is not paid up on the day of 1 1 every month, the mobile company will also lower its credit rating.
