Pay attention to Unicom WeChat to send traffic.

Unicom pays attention to WeChat traffic, which is usually a WeChat channel promotion activity launched by local Unicom. You can follow and bind the official WeChat account according to the activity requirements, and then receive free traffic exchange or get free traffic according to the guidelines. As the promotion activities vary from place to place, it is recommended that you go to the activity page to check the activity description or contact the local manual customer service for details.
