The 5 Best Cell Phone Signal Boosters [June 2021]

The main purpose of a cell phone signal booster is to improve and amplify cellular connectivity. Otherwise known as amplifiers or repeaters, cell phone signal boosters usually consist of three parts – an exterior antenna, a booster, and an interior antenna. The four companies that produce the best cell phone signal boosters are Cel-Fi, weBoost, SureCall, and HiBoost.

The way they work is by amplifying cellular reception and signal strength in your house, workstation, and even in your vehicle. They also improve internet speed and maintain a stable connection by detecting the most reliable signal from nearby cell towers. There are various types of cell phone signal boosters, such as analog signal repeaters, smart signal boosters, in-car cellular boosters, boosters for commercial buildings, etc.

If you have problems with weak cell service or internet speed, then getting a cell phone signal booster is something you should definitely consider. They can be life-savers, especially if you work from home. In this article, we will go through the best 10 cell phone signal boosters and exactly why you should get them for your home, office, or car.

The SureCall Flare 3.0 also has a very stylish, modern design, so no matter where you place it, it won’t ruin your home’s interior aesthetic.

03 weBoost Drive Sleek

The weBoost Drive Sleek is intended for vehicle use. Signal boosters meant for vehicles generally function differently from home or building signal boosters. While house-based signal boosters aim to cover a wide area, vehicle-based signal amplifiers are more effective in smaller spaces.

The Drive Sleek, for example, can only amplify one device at a time. Therefore, it’s the ideal signal booster for solo drivers. It also comes with a boosting cradle that keeps your device secure, and you can fit any phone from 5.1 inches to 7.5 inches long. What’s more, it doubles as a phone charger, ideal for long trips or car rides. When it comes to compatible types of vehicles, you can place this booster in your car, truck, van, or SUV. Once you turn it on, it will reduce dropped calls, eliminate dead zones, and improve cell service, mobile data, streaming, and voice quality.

Furthermore, it’s compatible with Verizon, AT&T, Sprint, T-Mobile, US Cellular, and other carriers. You don’t need any tools to install this signal booster since it only consists of a couple of pieces that can be set up easily.


  • 5G compatibility
  • FCC approved

  • Affordable
  • Comes with a boosting cradle


  • Only one device at a time
  • No band 41 or 71 support

04 Cel-Fi Go X

The Cel-Fi Go X is one of the most popular cell phone signal boosters on the market. The main reason for its popularity is the fact that it’s the only 100dB single-carrier cell phone signal booster around, which is about 40dB higher than other products.

On the other hand, it’s best suitable for a single device. It also comes with its own app, called the Cel-Fi WAVE App, which you can install on Android and iOS devices. Once installed, you can use it to control and monitor the Cel-Fi Go X, choose which carrier you want to boost and which bands the device amplifies, and much more. In terms of carrier compatibility, it supports AT&T, T-Mobile, Verizon, and US Cellular. However, it isn’t compatible with Sprint or Verizon 2G and 3G services.

The weBoost Home Studio is relatively small, which makes it ideal for small homes, apartments, offices, and single rooms. It minimizes dropped calls, enhances internet speed, and maintains a stable connection.

This cell phone signal booster only consists of two pieces: the outside antenna and the booster. The strength of the booster depends on the cell signal outside of your home. For example, if the outside cell signal is strong, then the amplifier can transmit the signal to larger rooms. The weBoost Home Studio works with 5G technology and is compatible with all U.S. carriers. One of the best features is that it can be used by multiple devices.

Once you purchase the booster, there are no additional subscriptions or fees. What’s more, it comes with a two-year warranty and a 30-day money-back policy by the manufacturer.

Not only does it come with a smart LCD display, but the HiBoost app that you can install on your phone. The LCD display allows you to install the booster easily, and you can also use it to modify settings and broadcast a signal which is received from the outdoor antenna.

In addition to all U.S. carriers, it’s compatible with Canadian ones as well. Furthermore, it works with all 2G, 3G, 4G, and even 5G technology.

The weBoost Home Complete can cover an entire house. To be more precise, as long as the outer signal strength has five bars, the booster can cover up to 7,500 square feet. That being said, due to the vast area it covers, it’s also an expensive signal amplifier. Another great aspect of the weBoost Home Complete is the fact that it can be used by multiple carriers.

It also offers maximum coverage, meaning that it can be used by businesses with employees who use different carriers and networks. Considering that this model comprises a fair number of parts, such as an outdoor directional antenna, an inside antenna, the booster itself, and lots of cables and small pieces, it’s best to hire someone to install it professionally. Once you have everything set up, you will receive a faster connection, better audio quality, better network speed, and it even gives you two additional hours of talk time.

If the outdoor signal strength has five bars, then the SureCall EZ can cover up to 2,000 square feet. But if it has three or four bars, then it can only cover 1,000 square feet. In other words, it can only cover one or two rooms the most. It only consists of three pieces: the EZ 4G kit, a desk antenna, and a coax cable.

Therefore, it will only take you a minute to set it up, and you can put the drill away. The minimal and modern design makes it completely unique. Wherever you decide to install it, it won’t distract from your home’s aesthetic. What’s more, it’s compatible with all U.S. carriers, and it can support multiple devices at once.
