Universal EMF Protection + Radiation Blocking Cell Phone Case

One Case That Shields Any Phone You Own

Every smartphone — regardless of brand, model, or generation — transmits Radio Frequency (RF) radiation from cellular, WiFi, Bluetooth, and 5G connections, and Extremely Low Frequency (ELF) radiation from its battery and internal circuitry. These emissions are strongest at the point of body contact and are present every time the phone is powered on, even if it’s not actively in use.

The DefenderShield® Universal Phone Case puts Ultra Armor+® Shielding Technology between you and whatever phone you carry. The front cover contains a multi-layer metallic composite that blocks up to 99% of directional EMF radiation from 0 to 110 GHz — covering all three 5G bands, 4G LTE, WiFi, Bluetooth, GPS, NFC, and RFID. The “+” in Ultra Armor+® means ELF shielding from the battery is also included — the frequency band most competing phone cases leave out entirely.

Close the cover and position it between your body and the phone. Think of it like a lead apron at the dentist: the shielding protects what’s directly behind it, while the rest of your phone stays fully connected. Your cellular signal, WiFi, and Bluetooth remain fully functional.

EMF shielding performance verified through FCC-accredited lab testing.

Attach, Magnetize, Carry

Unlike DefenderShield’s model-specific iPhone cases, the Universal Phone Case does not include a fitted inner nesting. Instead, it uses an included adhesive magnetic plate that you adhere to your existing slim phone case (or directly to the phone). The plate magnetizes to the inside back cover of the DefenderShield Wallet Cover, holding the phone securely in place. When you want to take a photo or use the phone without the wallet cover, pull the phone off the magnets and reattach when done.

The wallet itself is built from scratch-resistant vegan leather with a textured diamond-grain microfiber interior. Three RFID-blocking card slots hold your daily cards behind wireless-skimming protection. The included clip-on wrist strap turns the case into a clutch. The back cover folds into a landscape stand for hands-free viewing, and a magnetic tab closure keeps everything secure.

Available in two sizes — Standard (phones up to 6” × 3.2”) and Large (phones up to 6.5” × 3.2”) — and three colors: Charcoal Black, Violet Purple, and Sage Green.

Replacement adhesive plates are available separately if the original loses adhesion over time.

🛡 Ultra Armor+® — Full-Spectrum RF and ELF Protection

The front cover blocks up to 99% of EMF radiation from 0 to 110 GHz, covering more wireless protocols than other shielding cases and going above and beyond in protecting from future frequency allotments: That includes all three 5G bands, 4G LTE, WiFi, Bluetooth, GPS, NFC, RFID, and ELF from the battery. Most competing phone cases address RF alone. Ultra Armor+® covers both in a single shielding layer, verified by an FCC-accredited lab.

📱 Universal Fit — One Case for Any Smartphone

No model-specific nesting. An adhesive magnetic plate attaches to your existing phone case or directly to the phone, then magnetizes to the wallet cover. Switch phones, switch brands, switch generations — the same wallet case and shielding move with you. Available in Standard (up to 6”) and Large (up to 6.5”). A few Samsung Galaxy phones have been found to be incompatible due to the magnets, including the Samsung Galaxy S20, A50, A10, A50s, A20, A52, A20s, A53, A30, A6, S21 FE, A70s, Z Fold 5, and Z Fold 6.

🔒 Three RFID-Blocking Card Slots

Hold up to 9 credit cards, IDs, or transit passes behind 3 RFID shielded slots that prevents contactless skimming. The wallet case replaces a separate RFID wallet for most daily routines — one fewer thing to carry alongside your phone.

📡 No Signal Loss, No Battery Drain

Ultra Armor+® shielding in the front cover faces your body. The phone’s antenna communicates through the unshielded back and edges. Signal strength, WiFi, Bluetooth, GPS, and battery life remain exactly where they were before the wallet cover went on. The shielding reduces what reaches you without asking the phone to work harder.

🔀 Magnetic Attach-and-Detach

Pull the phone off the wallet cover to take photos, use NFC, or mount the phone on a magnetic car phone mount. Reattach in seconds by aligning the magnetic plate. No clips, no tools — magnets do the work. The adhesive plate holds firmly to most slim phone cases.

🧪 Independently Verified — Not Self-Reported

DefenderShield publishes its FCC-accredited lab results for its shielding on its Technology page. See how it blocks the widest spectrum of RF and ELF frequencies possible. 

Getting Set Up

1. Choose your size. Measure your phone (with its current slim case on, if using one with the universal wallet cover). The Standard fits phones up to 6” × 3.2”. The Large fits phones up to 6.5” × 3.2”. Check the size guide for specific model references.

2. Attach the adhesive magnetic plate to your phone or phone case. Peel the sticker backing from the included plate and press it firmly onto the back of your existing phone case. We recommend attaching the plate to a slim case (not included) rather than directly to the phone — this protects the phone’s finish and makes it easy to remove the plate later if needed.

3. Magnetize the phone to the wallet cover. Align the metal plate on the phone with the magnetic area on the inside back cover of the wallet. The magnets will grip and hold the phone in place.

4. Load your cards and attach the wrist strap. Slide up to nine cards into the 3 RFID-blocking slots. Clip on the wrist strap for clutch-style carry.

For Maximum EMF Reduction

• Keep the front cover between your body and the phone at all times. Pocket: cover against your leg. Calls: cover between screen and face. Lap: cover facing down. The Ultra Armor+® layer is in the front cover — it works only when it sits between you and the device.

• Pair with Air Tube Earbuds for call protection. The case shields your body during pocket carry and your head during calls, but the Air Tube Earbuds can keep your phone and any RF or ELF signal even further away from your head during calls with a hollow acoustic tube. Together they cover the two highest-exposure contact points.

• Use the landscape stand to create distance. The cover folds into a viewing stand. Setting the phone on a desk or nightstand instead of holding it eliminates direct body contact during streaming, calls, or browsing. Pair with the Touch Screen Stylus to prevent any part of your body from coming into direct contact with your phone.

• Detach the phone for photos and car mounting. Pull the phone off the magnetic back cover to access the camera unobstructed, or mount it on a DefenderShield Magnetic Car Phone Mount. Reattach when you are done for continued EMF protection

Care Instructions

• Wipe the cover with a soft, lightly damp cloth. Avoid solvents and alcohol-based cleaners.

• Dust with a dry lint-free cloth.

• Keep the magnetic closure free of lint and pocket debris for a reliable seal.

• If the adhesive plate loses grip over time, replacement plates are available HERE on the DefenderShield website.
