Why does sending a text message to 100 10 always prompt the system to be busy?

When the Unicom system is busy, users need to handle or cancel related services, which will be affected. I suggest that if you can't cancel the business by texting, you can choose other ways to handle it, such as logging in to the online business hall and clicking self-service > business handling > new business handling on the homepage.

& gt If you unsubscribe from the business, the service you ordered will be displayed on the interface. After finding the service you want to unsubscribe, you can unsubscribe from the value-added service.

If you can't find the business that needs to be unsubscribed, you can also call the local hotline 100 10 or go directly to the local business hall to cancel.
