What should I do if I want to unsubscribe from China Mobile 10 SMS package?

It seems that the landlord used a M-Zone card. 1SMS package in 0 yuan is mandatory and cannot be returned. The landlord can only change the card. I just changed it. If you don't want to use SMS package, you can change it to 10 M-Zone card, which is suitable for students. Just take your ID card and student ID card and go to the mobile business hall to change it. I hope the landlord will adopt it
