illegal solicitation to private SMS cell. very upset

I received the following text message on my cellphone at 12:18 am (EST) today:

MedsRxTablets.RU; Got my Xanax, Soma, Phentermine there. Also found cheap software for Mac's & Windows: TopSecretDigitalOne.com.UA 30% OFF Code: D33W-2012

I am extremely upset about this and unsure as to how to prevent more unsolicitated texts from telemarketers.
