Hello Cyndi1958,
Welcome to the community!
That does indeed sound like SPAM! Thanks for flagging it! As mentioned here, you can also forward these messages to 7726 (SPAM). Once audited, it will be used to augment the SPAM filter (see here). Unfortunately, as fast as these messages get blocked by the SPAM filter, the spammers/scammers find new ways to bypass the filter.
I understand forwarding those messages does not include phone number. However, it is unlikely the owner of the phone number is sending the messages. The scammers/spammers often use spoofed phone numbers when sending those messages and making SCAM and/or SPAM calls (see here).
Hope this helps 😀
Cheers
