Free SMS received in Yixin software does not display mobile phone number, but displays nickname?

1, at a certain time interval (24 hours), the same sender A sends a short message to the receiver B, and only the customer nickname+customer mobile phone number is reserved in the prefix of the first short message; 2. Clients A and B have exchanged more than three short messages with each other, and we think that they are completely familiar with each other, so when sender A sends short messages to the same receiver B in the future. SMS prefix only keeps the customer's nickname, and there is no time limit. Broadband on demand, fast thinking. The official account of China Telecom's Guizhou customer service WeChat can directly handle the keyword "Broadband on demand", which is convenient and fast. Customer service 42 answers for you.
