Best Bug Detectors For Cellphones 2024

Last Updated on November 3, 2022

 A bug detector is a great thing to have if you’re constantly traveling and want to be sure that your hotel room is clear of hidden recording devices such as cameras, for example. However, one of the best things you can go for is a cell phone bug detector, because most of the listening devices transmit information on the same frequency that’s used by cell phones.

Let’s get one thing out of the way, though. A cell phone bug detector isn’t a device you plug into your phone. Instead, it’s a detector that will instantly find any recording device that transmits data wirelessly, like a cell phone.

Take a peek at what we think are the best bug detector available today. And you can also check our learning guides on how to make a bug detector, or how to use a bug detector effectively! With that out of the way, let’s take a look at three bug detectors for cellphones you can use.

Best Overall

Receive frequency range: 1MHz-8000MHz
Detection range: 10m for 2.4G wireless camera
– 15m for 1.2G
RF wireless signal detection

The sherry is our pick for the best cell phone bug detector. It’s simple, it works great, and the price difference with the other two detectors is more than justified. To begin with, it has a very wide range of frequencies it can detect, and it can also detect 1.2G to 5.8G hidden cameras.

The wireless signal detection feature works admirably, and it will capture any surveillance devices or 2G/3G/4G SIM card cellphones, even if they’re on standby. What’s also nice is that it can also capture GPS locating devices, as well as other types of car trackers or eavesdropping devices.

Another nifty feature is the fact that you can extend or retract the antenna as you see fit, and it also has visual cues on the display. If you want to find an eavesdropping device without there being audio cues that the person listening can pick up on, this is the way to go. Overall, the sherry is definitely the best cell phone bug detector on the market.

Best for GSM Devices

RF wireless signal detection
Battery: 1000mA

Even though all of the devices will pick up cell phones, if whoever is eavesdropping on you is using a GSM signal to transmit data, the Wattne is the device you want to have in your hand. Whether you’re in a hotel room, or private accommodation, it will help you easily and discretely find any potential listening devices.

No products found.

To begin with, it comes with a flexible antenna you can have pointing in any direction. It also has an adjustment dial on the top which will basically increase or decrease the sensitivity of the device, a feature that might come in handy.

You will also appreciate the strong anti-jamming functionality, as well as the wide range of frequencies it can detect. Similarly to the sherry, the Wattne detects not only RF signals and magnetic fields, but it also has laser scanning to help you with cameras. You can find audio recording devices, cameras, cell phone transmitters, and just about any other type of bug, including GPS trackers on your vehicle. It thrives, however, with GSM signals, and that’s why it’s worth having most. (1)

Most Versatile

Display :

Last but not least, we’ve got the Anti Spy RF Detector by JMDHKK. It’s perfect for a lot of scenarios, which is why we’ve declared it as the most versatile cell phone bug detector, and it’s great at what it does without making any big sacrifices.

To begin with, its main feature is to detect all kinds of bugs, with a range from 1Mhz to 8Ghz. It also detects wireless cameras that work at 1.2G, 2.4G and 5.8G. With an upgraded chipset and an excellent antenna, the JMDHKK is very accurate and reliable, and there’s a strong anti-interference with it, so you can be sure that it will find just about any bug.

It does also work with things such as GPS trackers and other vehicle tracking bugs, which makes it, as we mentioned, the most versatile bug detector on our list today. The price is also reasonable, and it should fit within just about anyone’s budget.

Wrapping things up

To conclude, you can’t go wrong with any of the cell phone bug detectors on our list. However, if you want a bit more in terms of build quality, you should go for the sherry. If you believe that you’ll need it most for GSM devices, go for the Wattne, and if you aren’t sure what you’ll need, get the JMDHKK, as it’s the most versatile of all.

In any case, the prices are pretty similar, and all of the bug detectors do a great job at justifying them. If you’re in the market for a cell phone bug detector, you’ll do a great job with any of them.
