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 !

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.

Does Nothing Right, Trains You Wrong

Secure VPN: trashed WiFi connectivity so thoroughly they had to send out a notice to all users saying not to use it. Was on mobile chewing data for a day or two before I noticed.

Breach Reports: per service, only for ones you explicitly enter. Quick, enter every online service you use. I use tens to hundreds over the course of several years. You’re better off just putting watches on Google News.

Personal Info Monitoring: the new hotness. Peppers me with breach reports for my (publicly exposed) email address that say the breach source is unknown—no way to follow up. Can’t turn off breach reports of primary email address at all or disable this monitoring. It’s like Bizarro Troy Hunt designed it.

Insecure WiFi Warning: super hit or miss on whether it’s called out. Has occasionally called out secure networks when it checked while handshake still happening.

So yeah, it notifies me when there’s a phone system update now and a couple of other BS things I already get notifications for from the original systems. And since it chatters BS alerts at you that you can’t fully disable it trains you to ignore security alerts.

What a terrible “service” this is. Avoid like the plague.
