I received many missed calls from same unknown Cell Numbers?

Question

I want to know that owner of the cell phone. So could anyone help me how to locate the Cell Phone Directory?

Answer 1

You will get calls from unknown numbers when the caller is using 'voip' (or simply use internet to call). There are a lot of 'voip' sevices available,chk hotfoon.com

Sometimes only one or two digit numbers like +1, +44, +88, etc will appear, then make sure that this is an 'internet call'

Answer 2

try to complaint to the customer support centre. And you can install a software called blacklist. With the help of that software you can block the unwanted calls.
