I often receive short messages with numbers beginning with 106586989. How to cancel this service?

You can cancel by texting 0000 to 10086 (after sending, you will be given a list of Monternet services you have subscribed to, and you can cancel by replying to the serial number. Or you can call 10086 to cancel the manual service, or you can cancel it on the website of the local mobile company. Of course, if you feel that you have not subscribed to these Monternet services, you can call 1086 to make a complaint.
