How does Unicom card open a flow refueling package through SMS?

Because the policies of different cities are different, for example, Hubei Unicom's 2G traffic refueling package (that is, 5 yuan's 30-meter provincial traffic package) business, for Hubei Unicom's 2G mobile phone users (note: 2G users who have joined Jingmen and Shiyan "Wo Jia" cannot handle this business), if they are post-paid users, they can edit LLJY or KTLLJY and send it to10 for processing. If you are a prepaid user, you can edit LLJYO (letter "ou") to 100 10. The order takes effect immediately and automatically expires at the end of the month. There is no need to unsubscribe, and traffic is not used across months. You can order up to 5 times a month. For more business information about the flow refueling package, please contact the customer service of the place of origin for details, subject to the policy of the place of origin.
