Apple iPhone6S/6 s plus: add spam text messages to the blacklist

1) we want to add the text message blacklist, so we only need to go to the text message interface of the iphone and click [contact]. Then we find the [I] icon next to the contact to be blacklisted. (As shown in the following figure)

2) Then, after opening the page, click [block this incoming number], and then click [block contact] in the pop-up menu. (As shown in the following figure)

Well, this will successfully prevent this contact from sending us messages and so on. As long as there is a message, it will be automatically filtered out. Of course, if you want to add a phone blacklist, you can only set the phone number, this is also simply in the contact, click to enter and then click to block this contact.
