10 Best Cellular Extender 2025 in the United States

The weBoost Home MultiRoom Cell Phone Signal Booster is designed to significantly improve cellular signal strength across a coverage area of up to 5,000 square feet, making it suitable for larger homes or multiple rooms. It boosts both 4G LTE and 5G signals, ensuring compatibility with all major U.S. carriers, including Verizon, AT&T, and T-Mobile, so you don’t have to worry about switching carriers for better signal reception.

This booster can reduce dead zones, dropped calls, and buffering, resulting in enhanced voice quality and faster data speeds, even in challenging environments like rural areas, basements, or metal buildings. The device supports every cellular device in your home without any additional fees beyond your current wireless plan. The included weBoost app assists with DIY installation by providing step-by-step instructions and helping you find the nearest cell tower, making the setup process more user-friendly.

Some may find the installation process a bit technical, especially when mounting the external antenna. Additionally, its price point may be higher compared to other signal boosters on the market. Despite these minor drawbacks, the weBoost Home MultiRoom model 470144 offers robust performance, reliable coverage, and ease of use, making it a top choice for those needing a comprehensive signal boosting solution.

The CEL-FI GO G41 is a strong choice if you’re looking to boost cell signals at home, especially for those using AT&T, Verizon, or T-Mobile. It supports multiple common frequency bands (700 MHz, 850 MHz, 1700/2100 MHz, and 1900 MHz), covering a broad range of signals used by these carriers. One of its standout features is the high gain of 100 dB, which allows it to cover up to 15,000 square feet—enough for most large homes or small offices. This is significantly better than many competitors that require multiple boosters to cover the same area. The inclusion of both a dome and panel antenna gives flexibility in installation, so you can choose the best fit for your space. Plus, it’s FCC certified, ensuring it meets government safety and performance standards.

The booster is 5G ready with a chipset that supports current 5G DSS technology and will get an update to support newer 5G NR later in 2024, meaning it’s somewhat future-proof for upcoming network improvements. On the downside, it’s a bit heavy (nearly 40 pounds) and comes in a large package, so setup might require some effort or professional help if you’re not comfortable with installing antennas. Also, while it’s designed for major carriers, it’s best suited for smartphones and may not support other cellular devices as well.

To sum up, if you want a reliable, high-coverage booster primarily for home use with top carriers and 5G support, the CEL-FI GO G41 offers a powerful and flexible solution, but keep in mind the size and installation considerations.

The HiBoost Cell Phone Signal Booster is designed to improve weak cellular signals in homes or offices up to about 4,000 square feet, covering 2-3 rooms comfortably. It supports multiple US carriers including Verizon, AT&T, and T-Mobile, working with 2G, 3G, 4G LTE, and 5G signals on common frequency bands like 12, 17, 13, 5, 25, 2, and 4. This means you can switch carriers without needing a new booster. Installation is user-friendly with a window cable option that requires no drilling, and the HiBoost app helps you find the best signal placement.

It features a smart chip for stable, carrier-grade performance and is FCC approved for safety. While it supports 5G, this is limited to 5G signals using existing 4G bands (Dynamic Spectrum Sharing), not the newer mmWave 5G bands, which may be a drawback if you want the absolute fastest 5G speeds where available. The booster includes outdoor and indoor cables for antenna connection.

This booster is suitable for users who have at least a minimal outside signal (1-2 bars) and want a straightforward, reliable way to boost cellular signals for multiple users inside a moderate-sized area.
