How do China Unicom customers send text messages to 10010 to check traffic flow?

If the limited-time traffic you are inquiring about refers to China Unicom’s free-time traffic package service, for example, Guangdong Unicom’s 3G “Play as You Want” free-time traffic overlay package service, you can edit CXSYW and send it to 10010 to query the remaining traffic information of the package. . If the problem still cannot be solved or the situation is not the above, it is recommended to contact the customer service at the home location to inquire. The customer service inquiry at the home location shall prevail.
