How to send SMS to Unicom card to open traffic! thank you

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 packets can be processed in the following ways: the corresponding SMS instruction can be sent to 100 10:

(1) 10 yuan Package: "KT3GLL 10" takes effect the following month, and "LJKT3GLL 10" takes effect immediately;

(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.
