The INVCALL Cell Phone Signal Booster is a powerful solution for homes struggling with weak cellular signals. Compatible with major U.S. carriers like Verizon, AT&T, T-Mobile, and Sprint, this booster supports 4G LTE and 5G networks, ensuring seamless connectivity for calls and internet use.

One standout feature is its dual-antenna system, which includes a high-gain outdoor directional antenna and an indoor panel antenna. This setup expands coverage up to 7,000 sq ft, making it ideal for large homes or offices. Users have reported significant improvements in signal strength, with some noting an increase from 1-2 bars to 3-4 bars after installation.

However, the booster’s effectiveness depends on proper placement of the antennas. Some users faced challenges due to insufficient cable length (30 feet) or difficulty aligning the antennas with cell towers. For optimal performance, ensure the outdoor antenna is positioned correctly and consider purchasing additional cable if needed.

The booster’s advanced AGC chip ensures stable performance, while the HD LCD screen provides real-time status updates. It’s also FCC-approved and comes with a 3-year warranty, offering peace of mind.

While the INVCALL booster delivers impressive results for many users, it may not completely eliminate dead zones in areas with extremely poor signal. Overall, it’s a reliable choice for enhancing cellular connectivity at home or in small offices.
