Why can't I screen the information fee of China Unicom?

At present, China Unicom is convinced that the shielding function in the whole network has been cancelled. You can send "GBYW" to 106559342 to apply for shielding the conviction of Guangdong Unicom. When blocked, the system will automatically cancel the customized Guangdong Unicom letter service for you. Sending SMS to 106559342 is free, and the cost of sending SMS to SP access number is 0. 1 yuan/article.

China Unicom's letter service cannot be blocked for the following reasons:

1 Value-added service is not enabled for your number;

2 Unsubscribe command or path is incorrect, so you cannot unsubscribe.

Tips: If the above guidelines still cannot be solved, you can contact the local manual customer service for feedback.
