866-967-6590

The number belongs to TrapCall - they can un-musk phone number that shows up as 'unknown'.

what company is this number from?

Many calls were placed to this number (or received, I'm not certain). Is there any way to get a number of the person that is currently using this device so that I can retrieve it?

Apparently, if you use "trapcall", everytime you use it, is 1 minute off your cell phone plan.  It cost me over $70 this month for the "free service".

Any idea on how to stop this number at all?? It has cost me more than 100 per month. If this is supposed to unmask unknown calls, how can I stop that service so that I can stop getting these charges for the minutes? Please help

If you are a trapcall user, you need to access your account online and modify your settings.  It is automatically set to send you a text message and an e-mail anytime their service traps a call for you from a number you have blocked.  All you have to do is change your setting to only send an e-mail to your e-mail address.  Once you do that, you will not have any charges to your cell phone.  Just be sure you do not have e-mail alerts sent to your phone, otherwise, you will still tick off minutes every time someone calls.

Except that depending on your call plan, you could have a 1-minute call forward fee for every call that is forwarded to trapcall's nunber.  My call-as-you-go plan charges 10-cents for every call that is forwarded to TrapCall, but the callers I have blocked receive a "The number you have dialed is no longer in service" message.   Hopefully they will not keep calling after receiving the message, and I can turn TrapCall off in a week or so.

outgoing call to this 1866-967-6590 appears on my bill very a few minutes apart.

I have this number on my bill and every time I try calling to see who this number belongs to, I always get a busy signal, it doesn't matter what time or how many times I call it, it's always busy.

Is there any way to block this phone number from my phone Co.?
