If you're attending a protest, your phone can be both a lifeline—and a liability.
Even in airplane mode, your device still emits signals. Law enforcement and government agencies can use surveillance tools like IMSI catchers (a.k.a. stingrays) to mimic cell towers, intercept your data, and pinpoint your location.
That means your phone can silently betray your identity, movements, and connections—without you even unlocking it.
Wired recently broke down how to protect your digital privacy at protests, and one of their top recommendations was using a Faraday bag to block all wireless signals.
Let’s break down why DIY methods like foil fall short—and which Faraday bags are actually built for the job.
What’s a Faraday Bag and Why Should Protesters Use One?
A Faraday bag is a signal-blocking pouch that keeps your phone completely offline. It blocks:
-
Cellular (including 5G)
-
WiFi & Bluetooth
-
GPS
-
RFID & NFC
-
Radio signals
When your phone is sealed inside, it’s invisible to outside networks—no location tracking, no rogue surveillance, no risk of remote wipe. It’s the same principle used in secure labs, only made portable for real-world use.
Why DIY Fixes Like Foil Don’t Work
You might’ve heard of wrapping your phone in aluminum foil or tossing it into a metal container. These hacks sound clever—but they’re inconsistent and easy to fail.
-
Foil tears easily and doesn’t fully block signal
-
Gaps in coverage can let signals leak through
-
You can’t test the effectiveness in real-time
Faraday bags are lab-tested, certified, and proven in the field. For something this important, DIY just isn’t good enough.
