I don't know how to refuse text messages.

This article will introduce the method of intercepting spam messages by Apple mobile phone.

Open SMS

Open the SMS of iPhone6, then go to the page for viewing the content of spam messages received, and then click the details in the upper right corner.

Turn on Do Not Disturb mode.

After entering the details, if you need to mute the notification of this conversation, just turn on the Do Not Disturb mode below (Note: After turning on the Do Not Disturb mode, the SMS sent by this number can be received normally, but there will be no ringtone reminder).

Block contacts

If you want to completely block this number from sending short messages and not receiving such advertising information, you can click the I icon behind the phone number, then choose to block this incoming number, and finally confirm that you choose to block contacts (note: setting a blocked contact is equivalent to blacklisting this number, and you will not receive any short messages or phone harassment from this number in the future).
