About Unknown caller

1. Application that facilitates making calls in secret so that the receiver can not see the sender's identity.

2. Now available the version without ads and hiding of calls from your android dialer!

3. To make it work you have to be activated with your operator the ability to make calls in secret, if you do not have you can call and you activate it, the application only automates a service offered by operators, if not it have activated is not the application. Thank you!
