SLNT - Silent Pocket

To truly stop your cell phone from tracking you, you must remove the battery. Many new phones feature a unibody design making battery removal near impossible.

To eliminate tracking without removing the battery try a faraday bag.

Faraday bags completely block all signals to and from your devices including Bluetooth and WiFi.

I typically power my cell phone down, and place it in the faraday bag any time I leave my home to avoid tracking. Texting and calling via Signal also works quite well on an iPod touch and they do not contain cell phone or gps capabilities. offers some great faraday bags.
