Step 1: Press and hold the Home button to invoke Siri. Once activated, ask Siri to “read unread messages.”

Step 2: Siri will sort of read the message (it is impossible for it to actually speak it in proper English), and then it will ask if you want to reply to the message. Say yes.

Step 3: Say anything. The actual content of the reply doesn’t matter. What matters is sending a message.

Step 4: Once the reply has been sent, you should be able to open the Messages app. From there, swipe to delete the entire conversation containing the string of characters, or tap and hold on the malicious message, tap More, and then delete the message from the conversation.
