Why can't I cancel the signature on the back of Unicom's SMS?

Value-added services in different provinces are opened and cancelled in different ways, so they cannot be cancelled. If the cancellation method is incorrect or the number expires, the cancellation will fail. You can log on to the online business hall/homepage and click on Business Handling Other Services Value-added Services My New Services to unsubscribe. Subscribed services will be displayed in the interface. After finding the service to unsubscribe, you can unsubscribe from value-added services.

If it is the "short message signature" service of Anhui Unicom, you can send the short message "ZXQM" to 10655555 to cancel. If the SMS signature service cannot be unsubscribed, please resend ZX to 10655555 to unsubscribe.
