Mobile phone bag Tianyi Fei is young, how to check the wifi password?

The universal account number of all mobile phone packages of China Telecom (including Tianyi Fei Young- 19 yuan /39 yuan) is ChinaNet. Send a text message to 1000 1 to get the password. Later, the mobile phone will receive a reply message from 1000 1, including prompt information such as password. For example, dear Tianyi users, your temporary password for surfing the Internet using Tianyi Broadband wifi is XXX, valid for 6 hours, and your package will give you some free domestic surfing time. After that, it is 0.02 yuan/minute in the province and 0.03 yuan/minute outside the province. PS: Before Baidu knows the problem in the future, please search online to see if there are any similar problems. I have answered this question three times.
