This is a standard cost trap. If it is built into the mobile phone, you can complain about Hisense.

You can also call customer service to manual service and ask to turn off the Monternet service master switch. From now on, your mobile phone number can stop any form of Monternet value-added service deduction. If you want to open QQ business or weather forecast in the future, you can also ask the customer service to turn on the Monternet service master switch for you.
