How often does the mobile company accidentally generate phone bills?

It is usually reminded once a month. Under normal circumstances, when the phone bill is 10 yuan, the customer service of China Mobile will remind you.

For GSM users, China Mobile will provide "two reminders" service before stopping. When the customer can only answer the phone without paying, the system will immediately send a warm SMS reminder to remind the customer to pay in time; If the customer still fails to pay the fee on time, the system will send SMS reminder again before shutting down to avoid unnecessary downtime due to special circumstances such as business trip and shutdown.
