How does Apple's mobile phone prevent the sending of harassing short messages?

1. Block specific contacts or numbers. Open the information application, select the contact or number that you don't want to receive SMS, click the icon in the upper right corner, and then select "Block this incoming number" to add the contact or number to the blacklist and block its SMS.

2. Filter unknown senders. In the settings, find the information application, click to enter the setting of "unknown and filter information" and turn on the function of "filtering unknown senders". The short messages sent by unknown senders will be automatically blocked and will not be notified.

3. Turn off the mobile phone network data. Find the option of cellular mobile network in the settings, and turn off "cellular mobile data", so that you won't receive iMessage information (a kind of information sent through the network) and reduce the amount of spam.

4. Use third-party applications. For example, Tencent Mobile Manager can set up spam message filtering and interception, and customize interception rules to effectively filter out unwanted messages.
