I just bought a mobile phone and received a text message from 10658830, saying congratulations on upgrading from ordinary member to senior member of wireless music club.

Did you just buy a mobile phone or a mobile phone card?

Mobile phone M-Zone will automatically have advanced membership of wireless music club when you open the card. If so, it doesn't matter. Bring your own unified card, just like the color ring back tone function. There is no need to cancel. The color ring back tone function cannot be cancelled!

Unified cancellation instruction of Monternet service, enter "00000" (five zeros) to send SMS port number to Monternet service provider, and all services customized by users at the SMS port of service provider can be cancelled, and confirmation information can be received.

Then you can try sending it from 00000 to 10658830. Or call 10086 and press 0 to ask manually.
