605-496-0139

Just answered a call from this number.  No one on the other end.  I'm going to have to block with extreme prejudice.

Same as above, but on call back, is a disconnected number.

Caller hung up after 3 rings, I have received several calls from the 605 area code "Sioux Falls,SD" and so far 100% of them have been scam calls so I feel comfortable adding this number to my call blocker post haste.

Robocall, similar to above reports, hang up after 2 rings with no message left. Appears just to be looking for active numbers. Now blocked.

received call from this number; no one on the other end.,

caller id say South Dakota...two rings then hangs up....blocked

Received a call from this number; no one on the other end.

Just got the call (apparently from South Dakota) at my business in Winnipeg, Manitoba. Everyday around 4 p.m. central time these calls come in. I don't answer them and they do not leave a message.

Nobody on the other end, then hung up in my ear.

The purpose of this call is to verify your number, expect more

4 times a week

Caller ID: South Dakota -- no response when I answer.
I am glad for this service, to compare others experience--thus--to blacklist this number in my phone.

I just rec'd a call from(605) 496-0139, I answered the phone and only heard silence??? Block!!

This number called me at 4:50pm just before dinner.  Phone rang 4 times.  Caller ID said Sioux Falls, SD.  I did not answer and they did not leave a message.  Since I don't know anyone in Sioux Falls, I blocked the number.

Low life scumbags trying to scam small businesses. They try to pose themselves as google and then charge for first page listing on google. Please stay away from these thieves.

Call of the weekend with no voice message left. And I block.

4 rings, hung up when I picked up. I agree with Fangulo above - number verifier. Called at 4:05. Block.

Another privacy abuser, silent call scum sucker

Called my business office at 9:30 am on a Sunday, they did not leave a message. I'm blocking the number.

Silent call. Presumably incompetent telemarketers or scammers.
