Mobile Phone Recording Devices
You can use special devices to record your cell phone conversations. (cell phone image by Alexey Klementiev from

In the early days of cellular technology, recording a conversation on a mobile phone was all but impossible. The electronics inside mobile phones tended to interfere with attempts at recording using the same methods that were successful on home phones. But today there are devices that can record both ends of a mobile phone conversation with ease. In many cases, this type of recording is relatively inexpensive, easy and legal.


CellTap, a device manufactured by JK Audio, is a small box connected to one mobile phone via the 2.5mm earpiece jack. A tape recorder or digital recorder is then hooked to the CellTap box. The device mixes the volume levels from both ends of the conversation so that all parties are recorded with equal clarity.

The CellTap device has the added advantage of a possible speaker connection, enabling the person using the device to amplify the conversation over external speakers for others in the room to hear live.

Olympus TP-7

The Olympus TP-7 phone recorder can record mobile phone calls or any other phone calls. The simplicity of its design makes it inexpensive. The TP-7 is essentially a small microphone for your tape recorder. Insert the cord into the microphone jack of your tape recorder, press record and trap the small, soft microphone between your ear and the phone. The microphone will pick up all the sound of the conversation, although the person using the device will likely be a bit louder in the mix.

Speaker and Recorder

One way to record a conversation on a mobile phone is to simply use a voice recorder. The mobile phone will need to have speaker phone capability for this technique to be effective. Once the conversation begins, place the caller on speaker phone and begin recording with the microphone on your voice recorder near the phone's built-in speaker.

While this recording may have some interference and echo from room noise, the audio should still be clear enough that you can easily hear what the person is saying. Of course, some people don't like to be on speaker phones, and it may be obvious to them that they are.


Remember that eavesdropping and recording a phone conversation can be an illegal activity. Federal law states that, in most cases, as long as one party to the conversation is aware the conversation is being recorded, then it is legal. But you should check your state laws to make sure the current statutes allow the same.
