What number should China Unicom dial to cancel the weather forecast service?

You can dial 100 10, press 0 and then press 1, and you can choose the manual service. If you ask how to cancel the weather forecast, he will answer (Unicom calls the 10 10 customer service hotline for free). This should be an instruction to send a short message, but I forgot what it was, so I asked you to ask the human service. In addition, you can also log in to the mobile phone business hall online through the online business hall or mobile phone. I wish you success!
