How to check the credit rating of China Unicom mobile card?

Customer grading service is provided by China Unicom to 4G, 3G, 2G and 4G, 3G and mobile phone users who have been online for more than 6 natural months (calculated from the month of access to the network, that is, starting from the 7th natural month) and meet the requirements of the real-name system. Mobile phone users of 2G/3G converged services (excluding wireless network cards) are rated based on the user's historical consumption amount and length of time on the Internet. From high to low, the levels are divided into "five-star customers", "VIP customers", " Loyal customers", "four-star customers", "three-star customers", "two-star customers" and "one-star customers" can enjoy the corresponding level of special service content. Star-rated customers can send text message CXXJ to 10010 to check your star rating and validity period for free. You can also inquire through the mobile phone hall, online hall, business hall or dial 10010 customer service center.
