SMS only shows numbers and names.

1, at a certain time interval (24 hours), the same sender A sends a short message to the receiver B, and only the user's nickname+the user's mobile phone number is reserved in the first short message prefix; 2. Users A and B have exchanged more than three short messages with each other, and we think they are completely familiar with each other, so when sender A sends short messages to the same receiver B in the future. Short message prefix only keeps the user's nickname, and there is no time limit. For more service benefits, please click on "official website" Customer Service 2 17 below to get your solution.
