How to send SMS when Unicom handles traffic packets?

The contents and processing methods of China Unicom's provincial traffic packets are different. I suggest you contact the Unicom customer service to find out how to handle the traffic packet. For example, 3G domestic traffic package can be handled in the following ways: you can send the corresponding SMS instruction to100/kloc-0: (1)10 yuan package: "KT3GLL 10/0" takes effect the following month, "LJKT3LL/kloc-" (2)20 yuan Package: "KT3GLL20" takes effect the following month, and "LJKT3GLL20" takes effect immediately; (3)30 yuan Package: "KT3GLL30" takes effect the following month, and "LJKT3GLL30" takes effect immediately.
