According to the information you provided, if you need to unsubscribe from today's headline targeted traffic package, you can click "Free Traffic Service" on the headline mall page, enter the successful subscription page "I want to unsubscribe", and follow the prompts on the page.
Tips: There is no other way to unsubscribe from the traffic query page except manual unsubscribe, and SMS unsubscribe and manual unsubscribe are not supported.
If in doubt, I suggest you call Unicom customer service.
