How to cancel punk preferred SMS?

Pengke's preferred SMS cancellation method is as follows (taking mobile as an example):

1, edit SMS 0000 and send it to SP service code or186201(186202, 186203). The system will return the list of Monternet services you ordered, and you can query the customized Monternet services. If you find any unnecessary services, please reply to the QX serial number to cancel the single service. In particular, the serial number is a numeric code in front of the reply message.

2. If they are all cancelled, you can directly reply 00000 to the SP service code.

3. Users can call 10086 for manual inquiry and cancellation, or go to the mobile business hall to cancel the subscription within 72 hours after ordering the SMS service, free of information fee.
