Called but no message.

Just got a call from this number and when I answered they hung up. I tried to call it back because it showed up as a Florida number and I have a Florida number so I thought maybe it was someone I knew, however when I called back I received a recorded message stating that my call could not be completed as dialed. I have sprint so I don't think it's just T-Mobile customers.

They are assembling active cellphone numbers lists which they then sell to telemarketers. Do not answer the call. If you do, they know your number is active and you go onto their list. That is THE purpose of caller ID...don't answer calls from numbers you do not recognize..

Called my cell phone and did not leave a msg.

called didn't leave messaged. I tried to return call and get a fast busy. thanks much to all of you who reported your activity.  I will put number in my blocked file.

Your scamming callers do not maintain this site or this web page. No callers can magically determine which numbers should not be called based on anonymous comments. Criminals who mass-dial and violate the Telemarketing Sales Rule have no plans to stop calling you no matter what you say and regardless of your DNC registrations. They need first to be sued or jailed.

do not call

annoying!!

Called my husband's cell phone around noon.  He answered and it was a recording for security system.  He hung up.  They have called back three more times in the past half hour, we are not answering as this is a cell phone with a certain amount of minutes and don't want to waste any arguing with these morons.  Just added this cell phone to the do not call registry, although I know that takes up to a month.  

Called my textfree number and when i call it back it says its not a working number

Called cell phone once and left no message. I read 800 notes.  Blocking the number on my iPhone5 was fast and easy...  tap, tap, done.

This is a spam advertising call or some promotion to my cell.  Unwanted, unneeded and I hung up before spiel started in depth

I just got a call from this number, did not answer it.  Called it back from a landline and was told number not in service.  Must be someone wanting to sell me something.  Call is now blocked.

These scammers make their money from the monthly monitoring fees customers will be paying for their "free" security system after it is installed.

How do they make a "living" putting a sign in your yard and giving away free security systems?  So they can break into your house?!

No one there when I answered.  Tried calling back but got a busy signal.  Just blocked the number on my cell phone.

I have Verizon and call was to my iPhone. Obviously this is not just a T-Mobile thing. Good thing I never answer ANY call from a number I don't recognize. I DO keep a list of these morons in Microsoft Word to refer to if necessary. So far the list contains 106 numbers, mostly scams and solicitors. If only there was a product that could block an unlimited number of callers.

just tried to call back the number and was told this number is no longer in service. Thing is they JUST called not ten minutes ago.

I received a call from this number at 11:52 am on 12/27/2013, of course I didn't answer and they left no message.
My cell phone carrier is through SPRINT.

I received a call from this number at 1:05pm on 12/26.  I have no idea who this is.  They did not leave a message.

I had calls from this number three different places.  No message like everyone else... now they're blocked for good.

386-361-4000 received call on my tmobile cell phone to get a free security system if I advertise a sign on my front lawn all year. I clicked yes to talk to a human and asked where they got my cell phone number. They said their corporation buys cell phone numbers from Tmobile. Tmobile sells all cell phone info to corporations to increase profits. They said if you don't want to get called, just cancel your cell phone service. They said they need to make a living too, and if you can afford a cell phone, then you can afford a free security system just advertising on your front lawn or if in a condo, a sign in your front window facing the street or sidewalk.

Recieved call at 3:23 pm and 3:00 pm and wife recieved a call at 3:29 pm. I noticed K11 is a T-Mobile customer as are our phones. Anyone else?

Gets call from this number and no one answers.

For Andriod, save the number on your phone. Click on the contact. There should be a way you can add the number to a reject list. I do it all the time.

They just called again how do you block the phone using the Android phone?

Same here this number continues to call me every time I answer it hangs up.

several calls, no answer and they leave no voicemail. I blocked number with iphone.

spam.. " you have been selected for installation of a free security system.. all we ask is that you put a sign of the company in your front lawn for advertisement..   pres 1 for more info. or 2 to be removed... " 2 click!!!
i just dont know how they got my cell if i dont use that number for anything other than family...  (i wonder if tmobile sells my info)
mfkrs P.O.S. all of them!!!

Just called twice in succession. One was a recorded message and the next was dead air. I get enough "spam" on my home phone and now my cell is getting to be just as bad.
