100-100-5080

Have received the same call. Have reported to national authorities--FBI.  Have googled an all the reverse number look ups provide no info.  Sometimes it says it is not a valid number.  Talked to A T & T cell phone service with no luck.  They indicated they could not trace.  I have the same phone as you.  It may not be evil, maybe just pranksters.  However, it does need to be stopped and people need to be caught.

I received my first call today.  However my husband has been receiving them all month long.  It will only continue.  My phone does not have a sliding option.  If you got the real voice mail, what was it?  My AT & T person said it might be a re-dialer of some sort.

i am getting text messages from this number, when i text stop back it tells me it is not a real number.  i am getting one or 2 texts a week.  they however did not show up on my bill.  i just called att and got no real answer either, except to pay for the new blocking plan.  i also however have a pantech breeze phone.

Same here. I just want to make sure I am not missing a real voice mail message/

It's coming from a Vodafone mobile phone in Egypt.  I'm not making this up.

I have a Pantech Breeze.  I have not been receiveing texts or calls from the 100-100-5080 number but I have also NOT called or replied in any way to the 100-100-5080.  However, when ANYONE calls and leaves a voice mail it shows the number came from 100-100-5080.  Always call your voice mail using the #1 key.  I called AT&T to complain a few weeks ago and was told I had to call Pantech and have them wipe out my phone and start all over again.   I pay AT&T every month.  They should offer to REPLACE the PANTECH phones for FREE.  It is their problem and if they can't fix it then I should not have to completely wipe out my phone memory just so my phone may get hacked again.  They should replace my hacked phone AND they should wave any activation fee.   ADDITIONALLY, sometimes I hear clicking on my phone which makes me suspicious that someone is actually hacking into my phone line and listening....Makes a person wonder if there is a phone tap on my phone!  It does not happen all the time....but it does happen.

Keep getting calls on my cell phone from this number 100 100 5080  how do I block the number

I'm getting them too from 100 100 5080, hundreds of times a day it seems.....SOMEONE HELP US POOR PEOPLE WITH PANTECH PHONES!!!! I need an OBAMA PHONE!!!!

stop calling  don't know who it is

I got this call. It is obviously not a standrd US number so I ignore itl and delete it.

How do you make this number stop calling??  It calls when I get a voice message, and covers up my VM.

I got a call from them and went to my voice mail, and it actually sounded like someone riding a skateboard or something... like they pocket dialed me or something. this was the first time though, and i just wanted to look up the area code and then found this... o -o i'm wondering if i should be worried?

***  Update *** Maybe fixed!!

It's obvious that alot of people leaving message here don't read the messages above, but I wrote that I contacted AT&T & this was showing up, on Pantech phones & a couple of others, when you had a voice mail.  To work around it, you only needed to press/hold 1 to get your voice mail message.  Anyway, just now, it appears to be working.  I received a message, and in the lower left-hand corner it said "Call".  When I pressed the left 'soft key', it dialed the correct phone # to get to voice mail.

For those of you who read these, try it.  Hopefully it's now fixed.

I got a call too. It was sent to voice mail and I got home and called back. They answered but I heard nothing.

The number that appears in my cell phone, when the phone is ringing is 408-478-0644. Once it goes to voice mail - no one leaves a message, the telephone number 'morphs" into 100-100-5080.  I tried check the 408 number but don't want to pay 95 cents to find out who it is registered to, if anyone.

I saw the answer below on another website and it makes sense to me -- I researched it when I got the 100 100 5080 number on my AT&T cell phone when someone was calling me but didn't leave a message:
            "It's your at & t voicemail calling you back that you have a voicemail,(or someone just hung up without leaving a message after the beep went off after your outgoing message). you have to call your voicemail and go into options (I think its the #4 key) to turn it off. My voicemail suddenly stopped alerting me with an alert sound so I turned on the callback to be notified and when it calls back it leaves that number 100 100 5080.

at&t, get a message that I have a voicemail. when I press the key to access the vmail, his number pops up instead of the regular vmail number! it says it is an invalid number. How is it possible fo some unknown entity to access this far so it looks like the normal at&t voicemail system is alerting you with a new message. This is strange and needs attention right away from at&t!

Have been receiving calls from this phone number for 4 days... they do not leave a message...for respond when I answer.  Who is this?  Sure it must be a scam.

They are now calling at midnight.    A few months ago I was getting the same type of calls ... their area code was 707 and they finally stopped and this one started.  I called AT&T and they were no help.

I got it on my cell phone when I was in Knoxville today.  I tried to call it back because I thought it was the security company on the new house.  It claimed that the call could not be completed as dialed.
