Recently, I changed the Shenzhen mobile service package and got a new service: weather forecast. So I will send a short message about 121 at every day to tell me the weather tomorrow.
At the beginning, I felt pretty good, and then I was not very good. When I receive a text message, everyone is habitually looking at it. I believe everyone has developed such a conditioned reflection, but this text message is not so significant. Over time, I will get bored with this service, however, this service is quite useful and cannot be canceled.
So today, I think for some reason: What message tag should be modified or added for the SMS protocol? This tag can be used to enable or disable the message to prompt the user. Of course, it still shows that the user has received the message.
Of course, you can also add this function to the mobile phone: For short messages that are not from the address book, do not prompt, only display. Haha
