I get text messages with attached website linksfrom this number. I don't know anyone from Mississippi. The text says that it's from "Frank".

I also got a text coming from this number. It used my real first name and claimed to be from "Alex." Also mentioned a website link. Was most suspicious because the only people I know named "Alex" would know that I do not, and have never, smoked tobacco. ;-)

Forward the text to 7726:

Security company Cloudmark created a spam messaging reporting service that nation’s major wireless carriers agreed earlier this year to start using. Now, customers of AT&T Mobility, Verizon Wireless, T-Mobile, Sprint and others can forward their text spam message to 7726. The mobile phone carrier will ask customers for the phone number that’s linked to the spam message so they and Cloudmark can start investigating.
