Hello, BarryBron!
Welcome to Apple Support Communities! We understand you're receiving several spam messages on your iPhone. We know this can be distracting and we'd like to help!
It looks like you reached out from the resource "Block phone numbers, contacts, and emails on your iPhone, iPad, or iPod touch". To confirm, were you able to take the steps to block these numbers/emails on your iPhone? If not, this will be the first step we recommend taking.
Should the messages continue to appear, you'll want to reach out to your carrier since they may have additional options for blocking spam messages.
"To report SMS and MMS messages, contact your carrier."
All the best.
