Domestic mobile phones always send Monternet messages automatically.

First change the mobile phone card to another mobile phone brand, and then observe whether the mobile phone will automatically send Monternet messages. If yes, it means that your card has been opened and will be charged all the time. Then you can only dial 10086 and ask the attendant to turn off Monternet for you. If it's not the card, just set it directly in the phone. This setting is usually set in the relevant network. What business do I think you should start? My previous mobile phone card will be the same. I'll just call 10086, and then I'll be fine. What you said just now seems useless to set it up online. When I say close Monternet, I mean you can't open anything about Monternet in the future unless you ask the staff to reset it. Please leave a message if you have anything. . . . . . . .
