No signal in.
No signal out.

Your phone reports your location hundreds of times a day, and that trail gets bought and sold. Your key fob answers anyone who asks, including whoever is standing outside your house at 2am. This sleeve stops both.

The Faraday Sleeve in black leather, flap closed.

Cellular 4G / 5G blocked

Wi-Fi blocked

Bluetooth blocked

GPS blocked

NFC / RFID blocked

Conductive layers wrap whatever you put inside and stop the radio waves trying to cross them. Close the flap and the connection is severed until you open it.

Stops location tracking

No cell towers, no GPS, no Wi-Fi triangulation. Your phone can't report where it is because it can't reach anything.

Stops key fob relay theft

Thieves amplify your key fob's signal from outside your house to unlock and start the car in your driveway. A fob inside the sleeve has nothing to amplify.

Stops skimming and remote access

Nothing can read your cards or your phone in passing, and nothing can be pushed to a device it can't reach.

How do I know it's actually working?

Put your phone in, close the flap, and call it from another phone. It should go straight to voicemail. Try Find My as well and watch the location stop updating. If either one gets through, send it back.

Does it stop key fob relay theft?

Yes. Relay attacks work by picking up your fob's signal through a wall and repeating it at your car. A fob inside the sleeve emits nothing to pick up. The sleeve holds a phone, a fob, and a couple of cards at once.

Will my alarm still go off?

Yes. Alarms are local to the phone and don't need a signal, so it rings on schedule inside the sleeve. It's quieter through the leather.

Will it fit my phone with a case on?

The sleeve is 8.3 by 4.9 inches, sized to take the largest current phones with a standard case. Very thick battery or wallet cases are a tight squeeze.

What about EMF?

The sleeve blocks radio frequency signals from entering or leaving while it's closed, and we describe it that way on purpose. We don't make health claims about EMF exposure. What we can tell you is how much signal the shielding material stops, which is independently tested at over 100 dB across cellular, Wi-Fi, Bluetooth and GPS frequencies.

Why would I want two?

One for your phone and one for your car keys is the most common pair. Relay theft happens where you park, so the fob sleeve tends to live by the door.
