What is the short message of the mall service?

I really need to be very careful I downloaded a video software before, and then permission management asked me to open the SMS, and I agreed. I didn't expect to send a message in the middle of the night to let me reply. I checked my mobile phone and said that I had opened the China Digital video and what monthly subscription was available, but I never ordered it at all! I just looked it up on Baidu, and many people have this situation. Suggest sending a text message to 10086 to cancel the business as soon as possible. Send it directly to 10086, and then cancel it directly if you don't order anything! If you lose too much, take your ID card to the business hall to find a staff member to solve it. Don't let go easily. My phone bill is so useless!
