Called my phone and no one left a message with the number.
I didnt call back-i didn't trust that it wouldnt be a scam.

If you have an iPhone from ANY carrier you have the option of blocking any or all of your contacts.You just go to the contact you want to block , page down to bottom , and click on BLOCK THIS CONTACT. If I get a spam call I add it to my contacts and in name field I enter BLOCKED.

I don't call back numbers I don't know and tell others to do the same. I then add the numbers to my contacts as Scammer A-Hole. If I'm in the mood I will answer the calls when they come up with: whispering, "I's done, but there's blood everywhere." Then I hang up. But I can't help picturing the A-Hole on the other end's expression on their face!

Not sure what mr. K means.  Before I  defected from Verizon to tmobile 2 years ago, i clearly remember their online number blocking site. You could block 10 numbers but only for about 90 days per number. I prefer to use an app like Avast to block locally bypassing the carrier.

I can't find an iOS version of Mr. Number in the App Store. Is it only for Android?

got a couple of these from them

Get a call from this number the other day...Google's it and these posts came up. I'm a new t-mobile customer and I hope this isn't a forecast of things to come...

Just rec'd call from this# Got another 407-934 call last week on the 6th. Hate this stuff!

Received call, didn't answer. Wish these people could get real jobs.

Call and hang up

They won't stop calling me

A co-worker and I both received a call from this number on our cell phones recently. Our lines are not related. In fact, we have different carriers. Neither of us answered. I also received a call from 407-934-5285 two days later.

Gads, what a bunch of yahoos arguing back & forth about blocking & who has & does what! Find a different forum for that crap.
Anyway, this caller left a recorded message & my VM caught the last part which said 'press 1 for your travel agent or press 2 if you have no interest in traveling.' This call was on my cell which is an iPhone 5 w/ AT&T which has call block so I did that and I'm moving on with my day

:-)

Just got a  call from this number on 3/12/14 @ 9:56 AM.  Unfortunately I answered before looking at the number.  Anything I should be on the look out for....ie, large charges on my cell phone bill, etc???

This is a spam. Everytime I call it from the log list, a recording says " the number can not be completed as dialed".

Got this call on my cell.
Didn't leave a message.
Did reverse phone look up and it's a Smart City Telecom Landline in Lake Buena Vista, FL

Thanks for the info. I got a call today 3-11-14 and I did not answer. It is very scarry people having different numbers and that one number just might be a spam if you answer.  Thank you for letting us know.

Third call from this number, they never leave a message.

Annoying... 407-934-3451 keeps calling me.  Called back *67 from land line and says the number you have reached is no longer in service, this is a recording,  2520.  

Called, they hung up as soon as I answered.

407-934-3451 keeps calling

left message saying I won a trip.  Going to Do not call list and report.

Children laughing when I answered.   I called it bac, automated message says call can't be completed as dialed.

I am also on the do not call cell list and got a call this morning around 8am. No voicemail was left and it said Buena Vista FL was where the call originated.  I can also block a few numbers on Verizon but they drop off after a few months I believe and you have to put them in again and like someone else pointed out, the callers change numbers.

Recording about a cruise deal.  Scam

I received a call but it did not ring. No message was left. I have family in Orlando and thought I should try it back. The number could not be completed as dialed. I hate that. I too am on a do not call list.

same as everyone

407-934-3451 called my CELL 2 5:22 PM (AZ Time) Mar 10, 14- did not answer as I have taken to not answering unfamiliar / out of local area codes calls, thank you 800 note folks .

This person harassing me I want to know who is it

Second time I get a call from this number to my California cell phone number in a month. They left no voicemail.
