How does Mobile independently inquire about the minimum consumption?

Mobile phones can query the minimum consumption by themselves: SMS query and website query, and the query methods are as follows:

First, SMS query:

Edit SMS: send ZDXF to10086; Inquire about the minimum consumption in the specified month: send ZDXF plus month and year to 10086. For example, if you want to inquire about the minimum consumption limit for March 20 13, you can send it to 10086. Second, the website query:

Search the mobile phone network with a browser; Log in to the mobile phone network; Click on my mobile phone, select personal information, and click on the monthly minimum consumption query to query the minimum consumption.
