Calls Blacklist Customer Insights

1. All in all, it does what it says it was going to do, with the least amount of effort in my part and has reduced annoying telephone calls to zero.F-A-N-T-A-S-T-I-C. A must if you have a cellphone in the U.S. Blocks all unrecognized numbers, not for you if you need to receive inbound calls from random numbers.

2. It's a well written, helpful, and non intrusive app.Since Verizon Filter requires you to pay for a subscription to block calls with specific when specific prefix numbers, I figured they'd never do anything to actually help the customer since they are making money on it.

3. My phone would ring anywhere from 6 to 10 times a day with Spam calls; now my phone is silent all day (accept calls from people I actually want to talk to) and I love it!!Very happy! I I know there are mixed reviews recently for this app, but my experience has been very positive.

4. In my case, I had a neighbor lady making crank phone calls from both private and unknown numbers.

5. I simply wanted to route ALL calls not in my contacts to voicemail, without an alert to me, and that is exactly what it does! It is AWESOME because I do not have any more spam calls.

6. So I found Calls Blacklist and it does just that without me paying (has ads).

7. The flexibility of the blacklist rules are great, but it would be nice if they worked.Update: since I've gotten a newer modern phone, the app does not work as well as I like.

8. I set it as the defaul phone app as it requested, and it somehow blocked FEWER calls, missing 90-100% of them.

9. When I first started using it, I didn't set it as my default calling app, and it blocked about 50% of the calls it should have blocked.

10. I just don't want any unknown calls and so set to that setting.Worked great until it suddenly didn't anymore.

11. I was pleasantly suprised to open it up a few days later and saw where it had blocked spam calls exactly how I had hoped.
