Receiving spam text messages appear to be sent to myself from my iPhone

Good morning Flynd204!

I see that you're having some trouble with spam text messages that appear to be sent from your number.

Just to confirm, is it only showing your name but the number is not your own? You can check by opening the text message thread. Click the contact icon at the top > tap the info icon > then click the contact listing here for its details. Is the number not your own? If that's the case, use these steps to block and report the spam text as it will not block your actual phone number: Avoid phishing emails, fake 'virus' alerts, phony support calls, and other scams - Apple Support As noted in the resource, the contact name is not always accurate when it comes to spam/phishing text messages.

When reporting messages received through iMessage, the number usually gets blocked as well but if it's a text message you'll need to use these steps to block the number: Block phone numbers and contacts on your iPhone, iPad, or iPod touch - Apple Support

Take care.

Hey Flynd204 ,

Thanks you for following up with that additional information. At this point, I would recommend changing the password associated with your Apple ID. Here's the steps to follow for this: If you think your Apple ID has been compromised - Apple Support

Have a good day.
