If you want to delete a text message on your iPhone, there are a few different ways to go about it. The first way is to open the Messages app and select the message you want to delete. Then, tap on the three lines in the top left corner of the message and select Delete. If you want to delete multiple messages at once, you can use the same method as above, but instead of selecting one message, you will need to select all of them by pressing and holding on each one until they all turn blue. Then, tap on Delete and confirm your decision. If you want to permanently delete a text message without ever being able to see it again, you can do so by opening the Messages app and selecting the message you want to delete. Then, press and hold on the message until it starts shaking (it may take a few seconds). Once it has stopped shaking, release your finger and tap on Delete. ..
