If someone has been blocked on your iPhone, you won’t receive any messages from them. However, you can still view these messages if you need to. Here’s how:
1. Open the Settings app on your iPhone.
2. Tap on Messages.
3. Tap on Blocked Contacts.
4. You will see a list of all the people you have blocked. Tap on the name of the person you want to view messages from.
5. On the next screen, you will see a list of all the messages that have been sent to you by that person. You can tap on any message to read it.
