Who called from 2016614562

That's weird because I just got an empty text from that number..

Also got  2 texts during the night with just the time.  Unknown name or ID.

I received an empty text at 1:00am from this number

Received blank txt from this number at 2:43 am est 12-10-2012 .... On callback it tells me that the phone number v-mail has not been set up ......  Who is this ?

Should not have called back; now they got confirmation that your phone is a valid number.
