SureCall Fusion4Home Cell Phone Signal Booster up to 2000 sq ft, Boosts 5G/4G LTE, Omni Outdoor Antenna, Home & Office Multi-User All Carrier, Verizon AT&T Sprint T-Mobile, FCC Approved, USA Company

PRODUCT FEATURES— The SureCall Fusion4Home cell phone signal amplifier boosts weak signal in 2-3 rooms, up to 2000 sq ft, inside any small home or office. This results in fewer dropped calls, improved battery life, higher audio quality, and faster data and streaming for AT&T, T-Mobile, Verizon, Sprint, Straight Talk, U.S. Cellular and many more. Fusion4Home boosts 5G/4G LTE voice, text and data signals for all North American cell carriers, including Verizon’s 5G Nationwide data signals
COVERAGE AREA— The indoor coverage area that the Fusion4Home creates varies based on existing signal at the exterior antenna location: 1-2 bars outside ~ 500 sq ft inside, 3-4 bars ~ 1000 sq ft, 5 bars ~ 2000 sq ft. If there is weak signal where the exterior antenna is installed, we recommend a booster kit that includes components to capture and broadcast a stronger signal, like the Fusion4Home Max.
BEST PERFORMANCE— Finding a location with consistent signal that the outdoor omni antenna can capture is important and will improve performance. Indoor coverage area is directly related to the existing signal strength available at the exterior antenna location. For best performance we recommend a minimum 30 feet of horizontal separation between the base station and exterior antenna. Without this separation performance will suffer and the coverage area will be reduced.
EASY INSTALL— Simply set up the omni outdoor antenna, run the cable into your home, and place the cellular amplifier (base unit) where you want. Other boosters require you to run cables or drill holes to install the indoor antenna, but not the Fusion4Home - the indoor antenna is attached directly to the amplifier.

Includes industry best 3-year warranty and lifetime US-based tech support. FCC approved signal boosters.

SureCall EZ 4G Plug-and-Play Cell Phone Signal Booster Kit for All Carriers 3G/4G LTE

COVERAGE AREA— The indoor coverage area that the EZ 4G provides varies based on existing signal at the window where the antenna is placed: 1-2 bars: desktop size area, 3-5bars: Up to one room. If there is weak signal at the window location, we recommend a cell phone signal booster kit that includes an outside roof antenna to capture a stronger signal, like the Flare 3.0.
PRODUCT FEATURES— Increases 5G/4G LTE voice, text and data signals for multiple devices on all North American cell carriers. EZ 4G delivers enhanced indoor cell coverage for clearer and more reliable voice and data performance while reducing dropped & missed calls and extends battery life for all cellular devices.
EASY INSTALLATION— Plug-and-play signal booster with a simple DIY install that sets up in minutes without the need to drill holes or mount an outdoor antenna. EZ 4G is designed for locations that have cellular signal where the window antenna is placed. As with all signal booster products, EZ 4G cannot create signal where there is none. Instead, the antenna captures existing signal, amplifies it and rebroadcasts the boosted signal to an area of otherwise poor or non-existent coverage.
BEST PERFORMANCE— Having a location with consistent useable signal that the window antenna can capture is a must to experience a boost in signal further indoors. Coverage area is directly related to the existing signal strength available at the window location. A minimum of 30 feet of horizontal separation between the base station and window unit is a must. Without the proper amount of separation, the coverage area will be reduced to a personal sized space or smaller.
BUILT TO LAST— Designed in the USA with the high-quality components for longevity and connectivity where you need it most. Includes industry best 3-year warranty and lifetime US-based tech support. SureCall is proudly American owned and operated– US company based in Silicon Valley California. SureCall is an Authorized Verizon 5G Signal Booster Vendor.
