Tracking devices are small electronic devices that can be attached to objects or vehicles to track their movements. These devices are commonly used for monitoring fleet vehicles, keeping track of valuable assets, or even for personal use to track the location of a loved one. While they can be useful tools, there are concerns about their potential misuse, such as unauthorized tracking of individuals or invasion of privacy.
As tracking devices have become more common, so have concerns about privacy and security. Some people worry that these devices can be used for unauthorized tracking or even for stalking. Also concerns about the security of the data collected by tracking devices, as it could be intercepted by hackers or other unauthorized parties.
Different Types of Tracking Devices
Tracking devices come in two types, and each type operates differently.
Here are the two types of tracking devices:
GPS tracking devices
GPS (Global Positioning System) tracking devices are the most common type of tracking device. These devices use a network of satellites to determine the device location. GPS tracking devices can be small and discreet, so it’s easy to hide in vehicles or other objects. They are commonly used for fleet tracking, personal tracking, and asset tracking.
RF tracking devices
RF (Radio Frequency) tracking devices use radio waves to determine the device’s location. These devices emit a signal that can be picked up by receivers, allowing the device’s location to be tracked. RF tracking devices are commonly used in inventory tracking, supply chain management, and wildlife tracking.
How to Detect a Tracking Device Using a Cell phone

If you suspect that someone is tracking you, there are a few ways to use your cell phone to detect a tracking device.
Here are two common types of tracking devices and how to detect them:
1. RF tracking devices
RF tracking devices use radio frequencies to communicate with the device that is being tracked. To detect an RF tracking device, you can use your cell phone to scan for the presence of radio frequencies. There are several free apps available on both iOS and Android devices that can help you scan for RF signals.
Steps to detect RF tracking devices using a cell phone:
- Turn off all electronic devices in the area, including the cell phone you’ll use for detection.
- Open the phone’s dialer app and type in “*#21#“. This will display a list of call forwarding and forwarding options on your phone.
- Look for any phone numbers or forwarding options that you don’t recognize. Suspicious numbers may indicate the presence of an RF tracking device.
- Use a radio frequency detector app, such as Hidden Camera Detector to scan the area for any signals that could indicate the presence of an RF tracking device.
- Move the phone around the area and pay attention to any changes in the app’s signal strength readings. If there is a sudden increase in signal strength, it could be a sign that an RF tracking device is nearby.
2. GPS tracking devices
GPS tracking devices use satellite signals to determine their location. To detect a GPS tracking device, you can use your cell phone’s GPS to look for any suspicious signals.
Steps to detect GPS tracking devices using a cell phone:
- Use a GPS tracking detection app, such as GPS Test, to scan your surroundings for any GPS signals.
- Look for any GPS signals that appear to be coming from an unknown source or device.
- Move around the area and pay attention to any changes in the app’s signal strength readings. If there is a sudden increase in signal strength, it could be a sign that a GPS tracking device is nearby in your vehicle or house.
Additional Ways to Detect a Tracking Device
If you suspect that you are being tracked, there are other methods you can use to detect a tracking device besides using your phone.
There are several additional ways to detect a tracking device beyond using a cell phone. These methods may require specialized equipment or knowledge, but they can be effective in detecting various types of tracking devices.
Use of bug detectors
Bug detectors are kind of devices that can detect the presence of hidden cameras or microphones in a room. They can also detect the presence of GPS trackers or other RF tracking devices. Bug detectors work by detecting the radio frequency signals emitted by the tracking device. They can be handheld or stationary and come in a range of prices and capabilities.
RF signal detectors
RF signal detectors are similar to Bug detectors, they can also detect the presence of RF signals, including those emitted by tracking devices. They work by scanning the airwaves and detecting signals within a certain frequency range. Some models can also pinpoint the location of the signal source. RF signal detectors can be useful for detecting hidden cameras or microphones, as well as GPS and other RF tracking devices.
GPS jammers
GPS jamming devices emit radio signals at the same frequency as GPS signals to block them. They can be used to prevent a GPS tracking device from sending location data to its intended receiver. However, it is important to note that the use of GPS jammers is illegal in many countries, including the United States, and can result in hefty fines and other legal consequences.
Final Thoughts
Although a cell phone can detect some types of tracking devices, it may not be effective in all cases. To ensure complete protection from unwanted tracking, it is essential to utilize additional tools and methods like bug detectors and RF signal detectors. Being knowledgeable about different tracking devices and their detection methods is crucial for maintaining privacy and security in an interconnected world.
