Call Blocker Block Spam Calls Customer Insights

1. Maybe it does not allow wildcard blocking and therefore you have to painfully enter every numbers instead.It didn't block any calls & why do I have to go into the app and manually put in the numbers that I want to be blocked.

2. Then what's the point!? -USELESS! I Uninstalled it! The Developers need to work! (Don't unstall!)No instruction on how to block incoming call numbers that start with "3".

3. I'm so, desperate will still give it a try.I installed sgsin & uninstalled again, it's the SAME... NO NOTIFICATION AT STATUS BAR! ...did not even see a notification that I received a blocked call, so how would I know if I received a call & if I need to text who would it be?Great app.

4. Why did it give me the option to block my contacts, if I didn't want to talk to them they wouldn't be a contact.

5. Good news is that the unwanted call blocker mode is very functional.This is a horrible app.

6. Indeed it does not block unwanted txt msgs but that's not of my main concern right now.

7. My main issue is that ever since I downloaded this app, my voice echoes during phone calls as if my line's been tapped or eavesdropped upon by a 3rd party.

8. If you are that desperate to sell me that Trash, these products and services are likely not very good that they need to preach to me that desperately to get a sale.

9. ONE star worst contacts app when it comes to ads... Every single contact I added, one by one, from my contact list I had to see an advertisement!! This is unprofessional nonsense.

10. I tried testing it with my relatives line, and after blocking her number, she was still able to call me.

11. It doesn't block SMS/text messages.
