Cellular dead zones in the United States aren’t just a rural issue. Steel-framed buildings, energy-efficient windows, concrete walls, and distance from towers all block signals even in cities like Houston, Denver, or New York. When your phone can't connect reliably, its battery runs out and the radiation power increases. Moreover, connection problems interfere with work and daily life, and sometimes can even threaten your safety.
A certified signal booster fixes this by capturing faint outside signals even from distant Verizon, AT&T, or T-Mobile towers and amplifying them indoors or inside your vehicle. Unlike unapproved devices, our FCC-certified boosters are engineered to avoid interference and comply with all U.S. carrier requirements. That means safe, stable performance that actually works with your existing plan — no extra fees, no subscription.
Nikrans NS-12K-Voice, 3G & 4G PRO is a cool option for those who want to deal with all types of signal issues at once. With an indoor coverage area of up to 12,000 ft², this modern device can be installed in big office buildings, shopping malls, hotels, etc.
The booster is compatible with 5 frequency bands and can work with all the major mobile service providers in the United States. It also has an LCD screen on its body which will allow you to track the changes in the network state in real time.
Our systems support all major U.S. carriers and handle 4G LTE and 5G — the same frequencies that deliver nationwide coverage. Whether you’re:
you’ll enjoy full bars, crystal-clear calls, and fast mobile internet exactly where you need it.
Unlike DIY fixes or signal apps (which don’t actually amplify signal), our boosters deliver real, physical improvement by enhancing the radio connection between your device and the cell tower. We supply ready-to-use systems, each kit of which includes everything you need: an outdoor antenna, an indoor antenna, a booster box, coaxial cables, mounting accessories and a power supply. All you need to do is install the device, turn on the power and enjoy a stable signal in just a few seconds.
Yes. Our boosters are carrier-agnostic and support all U.S. networks: Verizon, AT&T, T-Mobile, and their MVNOs (like Mint Mobile, Visible, Cricket, etc.). They work with any smartphone or tablet — iPhone, Android, or other — without apps, settings, or SIM changes.
Not necessarily. It is important that there is at least a minimal signal in your room. Our team will consult you for free and recommend a suitable amplifying system, depending on your location, the size of the building and the operator.
Absolutely. All kits are fully portable. If you are moving, you can reinstall the same device in a new location. To cover more rooms or floors, simply add additional indoor antennas without changing the booster box. This can be done using the splitters available as accessories.
Yes. Every booster ships as a complete, ready-to-use kit with color-coded components and step-by-step instructions. Most customers install it in under 30 minutes using basic tools.
