Like seemingly everyone else in America, I was receiving multiple calls per day from scammers, each originating from a different number. Most days, I would get more scam calls than legitimate ones and, eventually, my frustration in dealing with them led me to send most calls to voicemail, assuming anyone who really needed to reach me would leave a message or send me a text.
After a while, I decided that it was ridiculous to pay a monthly cell phone bill just to be extremely annoyed and endlessly harassed, so I started hunting online for a technical solution. Blocking individual numbers manually using my phone’s native settings was a fruitless effort, as the scammers would just spoof a different number a few minutes later and my phone would ring again. And, as much as I would love to have flooded their lines in retaliation like one hacker did, I did not have the time, the know-how, or the infrastructure at home to conduct such an operation, as satisfying as it would have felt to do so.
The first potential solution I found was in the form of call-blocking apps. There are a number of options available in popular app stores for people looking to reduce and eliminate unwanted calls. Some are free to use and others require a one-time payment or charge a recurring monthly or annual subscription fee. There are apps that can block numbers from an entire area code, some that include an SMS-blocking feature, and even some that attempt to reveal the identity of the caller. The main problem I had with this option was the type of permissions these apps requested from my phone upon installation. Most, if not all, wanted read/write access to my contact list, my text messages, and my call log. Some wanted access to my location and, for some unknown reason, my photos, media files, external storage card, and Bluetooth-connected devices. As a Cyber Threat Intelligence Analyst, I’m highly skeptical of most mobile apps – particularly free ones and those developed in foreign countries – because I’m well-versed in mobile device threats and know the risk that downloaded apps can pose. However, most mobile device users, understandably, do not have or maintain the same level of awareness. (For more information about such threats, please visit the NJCCIC’s Mobile Malware Threat Profile.)
In addition to cybersecurity risks, I noticed that some of these “call-blocking” apps didn’t really block calls at all and, instead, merely labeled some of the incoming calls as spam while still providing a notification or an option to answer. Others appeared to lose some of their functionality if installed on newer, updated mobile operating systems. Customer reviews seemed mixed and I wasn’t quite sold on any of them. Quite frankly, many of the apps seemed like too much work to set-up and modify. I was looking for a one-time “set it and forget it” solution. That’s when I decided to see what options various mobile carriers offer, if any. Fortunately, mine provided a pretty simple and effective one and, so far, I have been very pleased with the results. For the benefit of our readership, we’ve put together a list of currently available call-blocking options per carrier.
