How do I check whether my SMS is rejected by iphone?

1. If you don't want to receive SMS from the same number in the future, open the received SMS first, there is a contact icon in the upper right corner, and click Enter. 2. After clicking on it, you can see that there are three icons below. Select the last one, which is painted on the circle! Icon, where you can set it. 3. After entering, pull it to the end. There is a number that can block this call. Click it, and then confirm to block the contact. You can block messages sent by this number, so you won't receive messages sent by this number next time. If you want to cancel, just choose to unlock this calling number in the last step, just like the previous step. 5. I want to say here that the SMS blocking mentioned by Bian Xiao can only be blocked for the SMS numbers that have been received, and unfamiliar numbers cannot be blocked directly. There are many other ways to block short messages, such as downloading software settings and so on.
