10086 sent me a short message saying that I activated the purchase discount for manual stations. The problem is that I didn't activate it or buy a mobile phone. I think there is.

Are you using a fake mobile phone? If your mobile phone doesn't have customized SMS service, you can call 10086 to turn off Monternet service. If you change the number of the SMS center without sending SMS, the message will not be sent automatically. Just send a message and change it. Don't forget to change it back after you send it. Closing Monternet service only turns off the switch of Monternet, but can't customize Monternet service, for example, it can't customize mobile newspaper, and the service of downloading information on the Internet on a monthly or monthly basis. Some mobile phones have some pay-per-view services, such as weather forecast. Or some built-in inquiry service, but it does not affect surfing the internet and answering the phone. You can only watch it online, but you can't download the deducted items.
