Great app

I used to get spam calls all day long, some day’s multiple times an hour! There were a few of them that had a robo dial that called 55 times in a row!! Since downloading and using Active Armor I don’t get ANY of those calls! You can set it up to have anything not in contacts to go directly to voicemail. The paid version includes VPN which is great! You can also set that up to start automatically every time you go to the internet. I haven’t had the issues mentioned in another review, it all depends on how you have your phone and internet setup. There’s a setting that says “block all cookies” if you have selected that, it won’t open sites because all sites use cookies and some are required in order to access the website. I tried that option once and it did block me from opening any website, as soon as I changed that setting, no problem. The VPN keeps your IP address private. I love this app! The only negative I’ve had is it doesn’t always update automatically, I have to go to the App Store and check for updates.

Good sometimes

I just received an identity alert, but I can’t access it. On the home/landing page, there’s a red exclamation point under the identity circle and says I have one ID alert. When I click the circle, it takes me to the next page and in the identity monitoring section it says 1 item detected but that’s it. It doesn’t show me what it is or anything about it. I’ve clicked all over that page and get nowhere. How am I supposed to take any action if I don’t even know what you’ve detected? Also, for the auto spam/fraud call blocking, I got 16, yes SIXTEEN notifications in a row, one right after the other of a number being auto blocked. In the call log, it shows all 16 calls from the same number. All within about 1 minute. It auto blocked it on the first call, so why did it then allow 15 more calls from that same number? I have the advanced subscription because it’s part of my cell service package, so I should be able to access every part of this app.

Don’t do it , vpn blocks wifi connection

I downloaded the armor security app because it won’t let you check your call protect app call log without upgrading to it, since I did that I would notice the word VPN at the top of my screen by my bars , I didn’t think anything of it cause I didn’t know what it was , my phone begin working very slow on apps I would get on, then I was unable to connect to my wifi at home , everyone else could except me , I’ve called mt internet provider an had them reboot my internet an it still wouldn’t connect. Spoke with Att an they redid my cellular data an reset network an it still wouldn’t work , my phone did this for 2 weeks I was miserable, an confused not being able to use my phone, I ended up having to speak with apple an they ended up helping figure out that it was the new app call protect made me download , we tried to turn the VPN button off an it would start working but somehow it would turn itself back on , I ended up having to delete the app, an now my phone works again. Thank god but I can’t check my call log on att call protect because it’s trying to force me to download mobile security AGAIN, I’m missing calls that aren’t in my contacts an can’t go back an see them unfortunately, I do not want to download this app again
