Can Unicom send a text message to check the phone bill?

Due to different policies in different cities and different package regulations, SMS inquiry methods are also different. For example, if you use Guangdong World Wind Package, you can edit HF and send it to 100 10 to inquire about the current phone bill, and edit HF20 to 100 10 to inquire about the monthly phone bill. It is suggested that you can also try to log on to the homepage of Unicom's online business hall and click convenience service > SMS instruction query to query the SMS instruction codes corresponding to different cities and further obtain relevant information (pictured). You can also contact local customer service for details.
