Be careful...27663 is from a third party "premium text messaging" service that gets added to your regular cell phone bill.  They sent me a text message after I tried to get a recipe online...cost me $9.98!!!!  Received a second unsolicited text from 25209, which also cost me $9.98.  I called my cell phone provider and they enlightened me.  This must be borderline illegal but at the very least unethical.  My cell phone provider put a Premium Text Block (forever) on my service so I can't inadvertently fall prey to these types of "scams".  Check your cell phone bill!  My provider took pity on my ignorance and gave me a one-time courtesy refund as I have been with this co. for many years.
