Your phone is a sophisticated radio receiver, but it is not designed to tune into the radio stations you hear in your car. Instead, it listens for specific cellular, Wi-Fi, and Bluetooth signals. If you want to pick up FM or AM radio frequencies, the method depends entirely on your phone’s hardware and whether you have the right app.
The simplest answer is that most modern smartphones can pick up FM radio frequencies if the hardware chip is present and activated. However, carriers often disable this feature. For other frequencies, like police scanners or aircraft bands, you need an external receiver that plugs into your phone. You cannot unlock these frequencies with software alone.
Does Your Phone Have an FM Radio Chip?
Most Android phones and many iPhones contain a physical FM radio receiver chip. This chip is the same hardware used to process cellular signals, but it includes a tuner for broadcast FM.
Having the chip does not guarantee you can use it. The phone manufacturer must connect the chip to the headphone jack or internal antenna. The wireless carrier must also enable the software. If either step is missing, the FM radio function stays dormant.
To check if your phone has an active FM chip, look for a pre-installed app called “FM Radio” or “Radio.” If you do not see one, download a legitimate FM radio app from your app store. Apps like NextRadio were specifically designed to activate the built-in chip on compatible devices.
You will likely need wired headphones. The headphone cable acts as the antenna for the FM signal. Without headphones plugged in, most phones cannot receive a clear FM broadcast.
How To Pick Up Radio Frequencies On Your Phone Using Built-In FM
If your phone supports it, the process is straightforward. Plug in your wired headphones and open the FM radio app. The app will scan for available stations in your area.
Here is the key distinction: this only works for standard broadcast FM radio, typically 87.5 to 108 MHz. This is the same band used by commercial music and news stations. It does not pick up police, emergency, or aircraft communications.
If the app says “No FM hardware available” or “FM radio not supported,” your carrier has likely disabled the chip. Some carriers have agreed to activate FM chips in recent years, but many still block it. If your phone does not support it, no app will fix that.
Using the built-in FM chip does not use your mobile data. It is a free service that works even without a cellular connection. This is useful during emergencies when cellular networks are congested or down.
Using Apps To Listen To Radio Stations Online
If your phone lacks an active FM chip, you can still listen to radio stations through internet streaming. Apps like TuneIn Radio, iHeartRadio, and Audacy stream thousands of local and international stations over Wi-Fi or cellular data.
This is not actually picking up radio frequencies. The app connects to the internet and receives a digital audio stream. You are not using the phone’s radio receiver at all. The distinction matters because streaming requires a data connection and uses your monthly data allowance.
Internet radio apps give you access to far more stations than a physical FM tuner. You can listen to stations from other countries or niche formats that do not broadcast in your area. However, if the internet goes down, the streaming stops.
For most people, this is the practical solution. It works on every smartphone and requires no special hardware. The trade-off is data usage and the lack of access during network outages.
Picking Up Other Frequencies Like Police and Aircraft
Standard FM radio is the only frequency band your phone can receive without extra hardware. Police scanners, aircraft communications, and marine radios use different bands that your phone’s internal chip cannot tune into.
To receive these frequencies, you need a software-defined radio (SDR) receiver. These are small USB dongles that plug into your phone using an OTG (On-The-Go) adapter. They typically cost between $20 and $40.
An SDR receiver can tune a wide range of frequencies, from AM broadcast bands to VHF and UHF ranges used by emergency services. You pair the hardware with an app like SDR Touch or Radio Scanner to control the tuning and demodulation.
This setup is legal to own and use for listening. However, laws vary by jurisdiction regarding what you can do with intercepted communications. Listening to police or aircraft traffic is generally legal in the United States, but using that information to commit a crime is not. Some states restrict listening to cell phone frequencies, which SDRs can technically receive.
Using a Portable Radio Receiver With Your Phone
Another option is to carry a separate portable radio and use your phone only for information. A dedicated handheld radio receiver is often more sensitive than a phone’s internal chip.
You can buy a pocket-sized AM/FM radio for under $20. Some models also include weather bands and shortwave frequencies. These devices have their own antennas and do not depend on your phone’s hardware.
The advantage is reliability. A standalone radio uses AA batteries and works in areas with no cellular coverage. It is a common recommendation for emergency preparedness kits.
The disadvantage is carrying an extra device. Most people prefer to consolidate everything into their phone, but a dedicated receiver is the most dependable way to access radio frequencies in remote areas.
Why Your Phone Cannot Just “Scan Everything”
People often expect their phone to act like a universal scanner. The hardware simply does not work that way.
Your phone contains multiple dedicated receivers, each tuned to a specific frequency range. The cellular radio handles LTE and 5G bands. The Wi-Fi radio handles 2.4 GHz and 5 GHz. The Bluetooth radio handles 2.4 GHz. The FM chip, if present, handles 87.5 to 108 MHz.
None of these receivers can be repurposed to hear other frequencies. The antenna design, the analog front-end, and the demodulation circuits are all optimized for their specific bands. Software cannot change what the hardware is physically capable of receiving.
This is why an SDR dongle is necessary for non-standard frequencies. It is a separate piece of hardware with a wideband tuner that can be programmed to listen across a broad spectrum.
Can You Use Your Phone To Listen to Ham Radio?
Ham radio operators use frequencies between 1.8 MHz and 1.3 GHz. Your phone cannot directly receive these signals without an SDR dongle.
However, there is a network called EchoLink and similar systems that connect ham radio repeaters to the internet. You can install an app that links your phone to a remote ham radio transceiver.
This allows you to talk to ham operators using your phone, but you are not actually transmitting radio waves. Your voice travels over the internet to a connected radio, which then broadcasts it. The reverse happens for incoming audio.
This requires a valid amateur radio license in most countries. The app itself does not require a license to install, but operating a ham radio station does.
Frequently Asked Questions
Do I need headphones to pick up FM radio on my phone?
Yes, for most phones with a built-in FM chip, wired headphones are required because the headphone cable serves as the FM antenna. Without them, the signal will be too weak to receive clearly.
Can I listen to police scanners on my phone?
Not with the built-in hardware. You need a software-defined radio dongle that plugs into your phone via an OTG adapter, along with a compatible scanning app.
Does listening to FM radio on my phone use data?
No, the built-in FM chip receives over-the-air signals and does not use mobile data. Internet radio apps like iHeartRadio do use data because they stream audio over the network.
Why does my phone not have an FM radio app?
Your carrier may have disabled the FM chip in the software, even if the hardware exists. Some manufacturers also omit the chip entirely to reduce cost.
