Question 1

Will this Faraday bag block all signals from my phone, including GPS and WiFi?**

Accepted Answer

The bag is designed to block cellular, GPS, WiFi, and Bluetooth signals—but effectiveness depends on fit. Many users on TikTok found it works well for smaller phones or when the pouch is fully sealed. For larger flagship phones (like the iPhone Pro Max or Samsung S23 Ultra), some reported weak signal leakage. If you need total isolation, we recommend testing the bag with a phone call while the device is inside, then adjusting the closure to ensure a tight seal.

Question 2

Is this actually a "signal jammer," or is it just a passive pouch?**

Accepted Answer

Great question—the title can be confusing. This is a **passive shielding pouch**, not an active jammer. It works by reflecting electromagnetic waves using metallic lining, rather than broadcasting any signal. Think of it like wrapping your device in a metal blanket. Several YouTube reviewers clarified this distinction, so if you're looking for active jamming technology, this isn't that product.

Question 3

I have a 2020+ car with keyless entry. Will this stop thieves from relaying my fob's signal?**

Accepted Answer

It usually works for basic relay attacks, but it's not 100% guaranteed for all modern vehicles. Some owners reported that their key fob still unlocked the car from 30 feet away while inside the pouch—especially with newer fobs that use ultra-wideband signals. For high-security use, we'd suggest layering with a secondary shield (like a tin box) or upgrading to a professionally tested Faraday pouch. But for casual parking lot protection, many Reddit users say it offers decent peace of mind.

Question 4

Can I still use my phone for calls or notifications while it's inside the bag?**

Accepted Answer

No—the bag is designed to completely cut off your device from all networks. Once the phone is sealed inside, you won't receive calls, texts, or notifications. That's the whole point of signal blocking. Some travelers use this intentionally to avoid distractions during flights or meetings. Just be aware: if you're waiting for an important call, keep your phone on the outside.

Question 5

How does this compare to more expensive Faraday bags like Mission Darkness or Silent Pocket?**

Accepted Answer

You're paying for the budget option here, and it shows in durability and consistency. Premium brands often use multiple layers of shielding, reinforced stitching, and tested RF attenuation ratings. This bag uses a simpler single-layer metallic lining—so it's fine for occasional use or for cards/keys, but if you need professional-grade security (e.g., for sensitive data or high-value vehicle protection), many buyers on Reddit recommend spending an extra $20–30 on a tested brand. For general privacy and RFID theft prevention, this two-pack certainly gets the job done.
