Think for a moment about just how sensitive your cellphone really is. Not only is it a device that you regularly use to make personal calls ― talking about all sorts of private and potentially compromising information in the process ― but it’s also a device that literally has more computing power than what NASA used to send men into space in the 1960s. It doesn’t just have your call history or text logs in it. It likely has your bank account information, photos that you don’t want falling into the wrong hands, your Web browsing history, and files and other documents that could be devastating to you, both personally and professionally, if they were to become compromised.

With all that in mind, it’s safe to say that protecting yourself from cellphone spying is important. Luckily, just as technology can be used to invade your privacy, it can also be used to protect it. If you really want to take the steps to safeguard your life from cellphone spying, there are a few key steps you’ll want to take.

The Wonders of Modern Technology

One of the major ways to protect yourself from cellphone spying is to purchase a device like the Protect GSM Safe 2. Not only does it offer built-in protection against any type of covert or illegal cellphone use, but it also detects any cellphone or cellular data use in the immediate area. This means that if there IS some type of bug or other electronic device siphoning your data and sending it elsewhere, this is the best way to find out about it.

Compatible with virtually all GSM cellphones, the Protect GSM Safe 2 also includes a built-in “white noise machine” for advanced counter surveillance. It automatically generates white noise while you make your calls, making sure that even if someone is trying to listen in, they won’t actually be able to gain access to a record of the details that call contained.

Tighten Up Those Settings

Many people don’t realize that the factory-set default settings on most smartphones do little to protect your privacy ― meaning that you could be being spied on from the moment you turn it on for the first time. This isn’t necessarily nefarious in nature ― it’s less “someone is trying to steal your confidential work information” and more “advertisers are trying to monetize your private data,” but it is concerning just the same.

Because of this, you should always go into the “Settings” app on your phone and immediately increase the privacy as much as possible. Turn off “share my location” or related features on all apps that don’t explicitly need it. Make sure you’re paying close attention to which apps you’re giving permission to access your call history, your text messages, your photos or even your emails.

Stay Alert

Though this won’t necessarily prevent someone from listening to your calls, one step that you should absolutely take to prevent general cellphone spying is to turn on features like two-factor authentication whenever possible. Two-factor authentication requires a second form of input in addition to a password to gain physical access to the device.

So instead of just putting in your password and unlocking all your data, you would usually need a specific code from an email to access the account in question. Even if someone does steal your password, without that second form of input, they wouldn’t be able to gain access.

Along the same lines, if your smartphone supports fingerprint authentication instead of passwords ― as is true with the Apple iPhone and many Samsung phones ― you should absolutely enable it. Passwords are far too easy to crack and even easier to guess, while it’s much harder for someone to steal your fingerprint. Even if you lose your phone, this will go a long way toward preventing someone from gaining unrestricted access to the confidential information hidden inside.
