What is the "unknown sender" in the message app? -Why that I can't hear anymore.
Speaking of SMS/mms on the iPhone, it is a "message" app, but do you know the "unknown sender" tab?Most people have no memory.
This "unknown sender" tab appears when the "Filter the Unknown Save" in "Settings" → "Message" is turned on.When you turn it off, the tab disappears, and a message that had been classified into the "Contact and SMS" tab is displayed on the entire screen.
In the first place, the word "unknown sender" refers to "a person who is not registered in the contact" and a message that has been sent as an IMESAGE.In other words, even if SMS/MMS arrives from a person who does not know at all or does not register the name, it will not be classified into a "unknown sender" tab.
The same is true for so -called spam.Occasionally, a suspicious MMS arrives, but it is not treated as an "unknown sender" unless it is an iMessage, no matter who is the sender.The "filter of unknown senders" switches do not take measures against spam.
In recent spam, the source of the source is often reached by the MMS of the e -mail address (SMS tends to decrease because communication costs are charged for each one).Since the "Message" app does not have the function of processing it as spam when MMS containing a specific word arrives, the basis of measures is to use a career spam filter function.
