Simket 2 Pack Military Grade Faraday Bags, Fireproof Waterproof Signal Blocking Pouch for Cell Phone & Car Keys, RFID GPS WIFI NFC Blocker, Anti-Tracking Privacy Shielding Pouch for Daily Travel

Love this thing! Works perfectly - put something in, no signal gets out or in. I don't dip this in water, but I have had them in wet areas and nothing got into the pouch Easy to use Durable Cost effective

Was skeptical at first but this product works. I literally put my work phone in this bag after it had five bars of service from AT&T and tried to call it from my personal phone less than 2 feet away which also had full service from Verizon. When I'm getting the call cannot be completed message since the call couldn't go through. Would recommend and would buy again.

Tons of these on Amazon claim to be faraday cage, but aren't. These actually work. Work great and fit easily into the pockets of my backpack. Actually scanned different things put in there, no signatures

These Faraday bags do what they’re supposed to do—block signals effectively and give peace of mind when you want your phone truly offline. Once inside, my phone had no signal, no Bluetooth, no Wi-Fi, which is exactly the point. The only downside is they’re a bit bulkier than expected, so they’re not the most convenient for pockets or small bags. That said, the quality feels solid and they work reliably. Great option if you want privacy and signal blocking without overthinking it.

These are great. Put your phone in and no one can track you. Put your bank cards in and no one can read them. It’s a faraday cage, just the right size for certain items. Love knowing my cards are safe from electronic theft.

I just received this product and have been impressed with it so far. It did block the signals as advertised. The top must be sealed for the signal to be blocked. If the top is open even on the sides it will not block the signal. Just FYI. The material is great and feels sturdy and has a coating on it that will resist water. I feel the phone, or whatever you would desire to put in the pouch/ bag would have good protection. It is a good size and my iPhone 16 had plenty of space. It is straight forward and easy to use. You get 2 bags so you are covered for multiple items. I would defiantly purchase again.

DO NOT BUY Simket Faraday Bags for Phones and Car Key 2 Pack, Signal Blocking Pouch, Cell Phone Signal Jammer, Car Key/WiFi/RFID/GPS Signal Blocker Black (m) I purchased 2 of these signal blocker bags on 6/25/2026. Both of them no longer function as designed. I use them daily in my car while driving. I bag my phone while in the car. I have a smart watch that is tied to my phone using bluetooth. The watch does not have phone carrier service. In the beginning while using the bags I would get no calls or texts to my phone and the watch would show a cloud with a line through it emoji (no signal). Now, while bagged, my phone receives texts, emails, and phone calls. The bags have failed in their designed intent. Why would this be? It seems that the material used in the construction degrades with time to the point of uselessness. Are you aware of this defect in design or material? Do you have a redress for this failure within a year of use? With proper materials and design these bags should function for years. If that is the design intent, then you should state that the bags will not function past a year. Also, the customer service email provided by Simket is a dead email.

Want to disappear? Go off the grid? Tired of your ex drunk-texting you all night? You need this. Put your phone in this bag and you are GONE. That phone ceases to exist. I tested it every which way I could think of and nothing. No signal came through. Not a peep.

Put my Samsung 24 into the bag and sealed it up with the Velcro and then rang my number with another phone next to it, and it did not allow the Samsung 24 to ring. Does what it was supposed to do.

Pretty good product, tested no signal escape from bag, fits good, works good, just one corner a bit frayed.

IT WORKS!

This faraday bag actually works. Does the job it claims to do!

Had it for several months now. It works perfectly. Nothing connects to my phone once it is in the bag. While I have only used it for my phone alone, it could likely fit another device in the bag as well.
