  1. I cannot get my iphone 6s with the lastest IOS work with any call blocker. I tried robokiller. It doesn’t show up in settings. I do not want to backup and restore my iphone in order to do this. I’m thinking of going android because I can’t get rid of these annoying robo calls.

    • You don’t want to go through the hassle of upgrading your iOS version, but will switch to Android. Great logic… “I don’t want to spend 1 hour of my time to get better security and features on my phone, however, I will switch to Android and have to learn a whole new operating system”. Genius!

  2. On my mind, the best app for detecting and blocking spam calls is CallHound. It allows to block calls from unknown numbers in one click, also to create filtering rules for blocking spam numbers. The app interface is very simple, and you can use CallHound without an Internet connection. In this app, it is also possible to backup rules via connecting to social networks, so you can always transfer the app data to another device. You should definitely try it out and make sure in its convenience https://itunes.apple.com/app/id1293775392.

  3. The reality is simple – cell phones on Android also get those annoying robo calls from som spoofed number that makes it appear to you it is a local call!
    The people behind these bogus calls are usually trying to turn you into a victim of one type or another! They should all be in jail with no phone privileges!!!

  4. We should just make it legal to have us do what we want to spam callers with full immunity. Allow us to humiliate, maim, and the problem will disappear in 90 days or less.

    • not likely as your main problem is tracking them down… the calls are bounced around server farms and they are most likely out of the country so … A) hard to find B) too much effort to logistically secure your target … plus you’re coming at these people on their turf so as soon as you pull that trigger you are going to get hounded… or caught.

  5. I think this article is missing one more awesome call blocking app – CallHound. I use this app, and I’m delighted with its work. App applies rules to calls and groups them as spam and unwanted. You can set your own rules to detect spam calls. Incoming calls for which Spam rules applied are completely blocked, and the call does not occur. No one, from advertising agents to strangers, can bother you if they are on your spam list. When you receive the call from a number for which the Unwanted rule applied, it marks as ‘unwanted’ on the screen. So, you can choose: to answer or not.

  6. Does anyone know if there is an app that allows blocking from numbers that mimic your phone number? For instance, I have Hiya. My phone number is 123 456 7989. Hiya allows me to block calls from 123 45, I need one that allows more digits in the blocking. (I got a spam call from my own number this week!!)

  7. Does anyone know if there is there an iPhone call blocker that gives the unwanted caller a message that the number is disconnected, unavailable, etc.? Also, I would like an iPhone app to bounce back blocked text messages to the sender so they would know I’m not receiving them? Thanks for any help.
