Very good app from a company we can trust

I am glad you are looking for the safety of your customers on such a complex technology as telephone and internet communications!
I could not explain how phone numbers are used from AT&T to call me and when I call back to the same number I receive a notification that the number is out of service even when my call back is done instantly after receiving the obvious SCAM call!
I always felt that it was the responsibility of AT&T to solve this problem and not charge us for the use of your solution as other apps do ( such as Numbers)!
Excellent app from a trustworthy and serious company !

It deserves 0 stars but it Won’t allow zero

I used this app for 6 months small issues until 2 weeks ago it started blocking everyone I mean everyone in my contact list, my husband, kids, parents, siblings, job, dr.’s office, attorney’s office, the calls don’t show up on my phone as missed calls, the calls don’t ring, I do not have my ringer off, I do not have DND on. 15 minutes later they appear in my voice mail and my loved ones text me asking why their calls keep going to voicemail.
It ask like a virus because I decided to delete it from my phone completely it started causing me to miss important calls. When I deleted it it was still blocking all my calls that I had manually unblocked before I deleted it. I had to download it again because I could not get any, zero calls, when I downloaded it again immediately unblocked in it’s list my contacts and not till then would my phone ring again. I am stuck with this virus I am afraid to upgrade to new phone because will this mess transfer when I spend $2000 on a new phone. I am stuck with it or my contacts cannot call me. It is working in reverse.😩😡🤬😭😤

VPN closes WiFi and forces data use

I downloaded Mobile Security a couple of months ago at the recommendation of AT&T. I’m a U-Verse TV and Internet Fiber customer also. Anyway, I started getting notifications from AT&T that I was about to exceed my 5GB plan when I had never came close to using 3GB in the past. As a precaution I switched to the Unlimited Plan. Then I noticed that my phone was sporadically connecting to WiFi. After being transferred from one CSR to a technician who could actually help me, she asked if I had any software that has a battery saver. I don’t. We did a Network Reset. While rebooting I starting seeing “VPN” messages. The lightbulb in my head went on then. After multiple attempts to turn off the VPN settings in Mobile Security and restarting my phone my only solution was to delete the application and restart. Since then I have never lost my WiFi signal.
My huge concern is that why does AT&T promote software that disconnects from their own routers on their own internet system and force cell phone data? Start the conspiracy theories.
