What is the serial number of China Mobile Service?

China Mobile customers can edit SMS 0000 and send it to 10086 for business inquiry and unsubscribe, so as to quickly inquire about various monthly value-added services subscribed by the mobile phone account so far. Customers can send instructions to reply to short messages according to the prompts, so that it is convenient to choose the corresponding service serial number to unsubscribe from one or more subscribed monthly value-added services (except those that cannot be unsubscribed due to signing an agreement).

As shown in the red box, you need to use the business serial number to unsubscribe from the business. Please understand.
