Yes, China Mobile does have some activities of opening blind boxes to collect traffic. For example, if you are lucky enough to open the blind box and get 100M-9G traffic, users can find the corresponding activity page through WeChat to participate in the lucky draw. In addition, there are other blind box unpacking activities in cooperation with China Mobile, and users can log in their China mobile accounts to participate in the lucky draw. These activities usually provide different amounts of traffic rewards, which users can get by participating in activities or drawing prizes.
However, please note that these activities may have certain restrictions and rules, such as the redemption and use period of traffic coupons, which are subject to the rules of the activities at that time.
