How do Unicom users open monthly SMS traffic service?

This depends on whether you use Unicom's 2G or 3G package. If it is a 3G package, if your number has been using the 3G package for more than half a year, you can order the 3G domestic traffic package. The way to open the traffic packet by SMS is to send the corresponding SMS instruction 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 next month, and "LJKT3GLL30" takes effect immediately;

(4) Send "QX3GLL" to unsubscribe.

If you are a 2G user, it depends on your city. It is suggested that you can send any letter or short message directly to 100 10 to get the service menu, and follow the prompts to order the traffic package service.
