Got a text message with a code of 3624 at 3:51 am on April 13, 2011, offering "home positions" paying $87/hour and directing me to news5bizopp.com. My phone co is T-mobile but they have said in the past they cannot block this type of call. Since I am in the do-not-call list for years, I filed a complaint (https://complaints.donotcall.gov/) and I'm posting this in all sites that track this crap.
206-313-0028 is a telemarketer message center. When I received calls and text messages from them, it was advertising for Larry Flynt's Hustler Club, Vegas and gave a secondary phone number of 702-795-3131. The best thing you can do is register your phone (cell or landline) with the National "Do Not Call" Registry https://www.donotcall.gov/default.aspx This way whenever you get unwanted phone calls you can file a complaint. Each time a complaint is filed they create a file and when enough complaints come in the perpetrator will be warned that if they do not cease and desist, they can face fines up to $11,000 a day and also be criminally prosecuted. But this only works, if you register and file complaints with this government website about these unwanted callers.
