I'll just tack this onto an existing thread with some good (though dated) security info.

FCC warns of steep rise in phishing over SMS is from Malwarebytes, software I pay for every year. Their newsletters are interesting.

I wasn't aware that there is a way to forward spam to the FCC before deleting it. The number to forward to is 7726 (SPAM). Look to the little dots on your phone when you have the text in front of you (but haven't clicked or opened anything!) and you'll find ways to forward. Then block the caller and delete the spam.
