I bought a Coco Beauty mask with my colleagues online before, but once there was an activity, my colleagues received a message on their mobile phones. Why didn't I?
There are several possibilities: first, did your colleague have a registered website member at that time? Second, their websites randomly select lucky users; Third, the signal there is not good and no information can be received; Fourth, see if there is any software similar to Tencent Mobile Manager installed on your mobile phone. It may treat these short messages with promotional words as spam messages, and you can look for them in the software.
