Excuse me, my mobile phone has the business of "mastering life", so what exactly is this business? Can I cancel?

I don't know if you bring it on your business card or your mobile phone. You can check your consumption records to see if you have spent the money. If you spend money directly in your communication company or Unicom, you can cancel it directly, or call their customer service number to choose manual service, or ask them to cancel it for you.

There is also a mobile phone when installing the system, which is basically bound and cannot be deleted, but as long as it is not selected, it will not cost money!
