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

Free Shipping

Main Highlights

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.
