What text message should I send on my mobile phone to cancel the Mobile Orange Plan?

If it is a value-added service, send 0000 to 10086, and then there will be a prompt. You can also call 10086. After dialing, you will be introduced by voice first, and then you can choose manual service. She will help you, but you need a password. If it really doesn’t work, I’ll go to the business hall at the end of the month...
