Why can't I open the SMS package?

Hello, at present, Shenyang Unicom can handle the SMS package of 3G post-paid package, but cannot handle the 3G pre-paid package for the time being. Except for the 80 SMS package 5 yuan, other SMS packages of 10 yuan, 20 yuan, 30 yuan and 40 yuan can be consulted in Unicom's own business hall at the place of departure. It is suggested that you contact the local manual customer service for consultation, which is subject to the policy of China Unicom.
