Product description
The SureCall Flare 3.0 is a whole‑home/office cell signal booster designed to fix weak reception for multiple users across all major U.S. carriers in spaces up to about 3,500 sq ft. It combines a powerful outdoor Yagi antenna with an attractive indoor “flare” unit, so you get strong performance without an ugly piece of equipment in the middle of your living room or office.
Coverage, Carriers, and 5G/4G Support
This system is built for multi‑user, multi‑carrier coverage. It boosts talk, text, and data for:
-
Verizon, AT&T, T‑Mobile, and legacy Sprint lines
-
Most MVNOs that run on those networks (Cricket, Metro, etc.)
The Flare 3.0 supports current 4G LTE and low‑band 5G signals (the 5G that uses the same frequency bands as 4G). That means you’ll see stronger bars and more stable data speeds for video calls, streaming, and hotspot use, even in fringe or partially shielded locations.
With proper placement, it’s rated for up to 3,500 sq ft, which is typically enough for:
-
A small to medium‑size house
-
A condo or apartment plus balcony
-
A small office suite or storefront
Real‑world coverage always depends on how strong the outside signal is, but the Flare 3.0 is designed to take a weak, marginal outdoor signal and make it comfortably usable indoors.
Yagi Outdoor Antenna and Indoor “Flare” Unit
The kit includes two main components:
-
Directional Yagi Antenna (outdoor):
This antenna focuses on the nearest tower to pull in the strongest possible signal. Mounted on a roof, eave, or exterior wall and aimed correctly, it can dramatically improve the quality of what your booster has to work with. -
Flare Indoor Unit:
Instead of a traditional box with a separate indoor panel antenna, the Flare integrates the amplifier and indoor antenna into one vertical “tower” that looks more like a modern speaker than telecom equipment. You can place it on a shelf, table, or counter in the area where you need coverage most.
By separating the outdoor Yagi and the indoor flare unit, the booster reduces interference and maximizes gain, which results in a more stable signal for everyone in the coverage area.
Installation and Everyday Use
The system is designed for DIY installation:
-
Mount and point the Yagi antenna toward the nearest cell tower (using your phone’s field test mode or a compass app can help).
-
Run the included coax cable inside and connect it to the Flare base unit.
-
Plug in power and let the system automatically adjust its gain levels.
Once set up, the booster works completely in the background. Phones, tablets, and hotspots connect to it automatically—no app or pairing needed. You should notice:
-
Fewer dropped calls
-
Clearer voice quality
-
More reliable mobile data, especially in rooms that previously had 1 bar or constant “buffering”
Because it is FCC approved and manufactured by a U.S. company, it’s designed to comply with all current regulations for consumer cell boosters. That includes built‑in safeguards to prevent interference with carrier networks and automatic gain control to keep the system stable even when outside signal conditions change.
Who the Flare 3.0 Is Best For
This booster is a strong fit if you:
-
Live or work in a fringe coverage area, or in a building where metal, concrete, or low‑E windows block cell signals.
-
Need to support multiple users and multiple carriers simultaneously—families, shared offices, or small businesses.
-
Want a booster that offers solid performance but still looks discreet and modern inside the home.
If your home or office routinely suffers from one‑bar coverage, dropped calls, or slow LTE in a space up to roughly 3,500 sq ft, the SureCall Flare 3.0 offers a polished, set‑and‑forget solution that can make mobile connectivity feel as dependable as your wired internet.
