When not having a cell phone signal just won’t do, turn to a cell phone signal booster. A booster is a smart solution to an annoying problem. The best cell phone signal boosters help banish weak signal areas by supporting calls and data from your mobile carrier. Most people associate boosters with residential homes. In all actuality, cell phone signal boosters are also available for office buildings, industrial spaces, and even vehicles located in areas where cell signal is not up to par. 

Boosters work by feeding off the service you already have. These devices use larger, additional antennas in addition to the one included with your phone or other mobile devices. Keep in mind that a signal booster helps when the signal is weak. Unfortunately, a booster is not effective in a dead zone where there's no cell signal at all.

In evaluating cell phone signal boosters, we closely examined range, frequencies, cellular networks, antennas, and ease of installation. Since signal boosters will work only if you have a modicum of cell service, you may want to first consider researching a provider more suited to your needs. Delve into our list of the best cell phone plans to determine if there's a better option for you. Otherwise, read on to see the best cell phone signal boosters.

Best Overall: SureCall Flare Cell Phone Signal Booster Kit

Surecall Flare Cell Phone Signal Booster Kit
What We Like
  • Reach of 2,500 square feet

  • Compatible with 4G LTE frequencies

  • Supports up to eight simultaneous users

What We Don't Like
  • Limited to mid-sized spaces

If you’re looking for a reliable booster that can serve a modestly sized home or office, works with 4G LTE frequencies, and allows multiple people to connect, the SureCall Flare Cell Phone Signal Booster Kit is the perfect solution.

This booster is ideal for a home or office as it’s capable of covering up to 2,500 square feet. Irrespective of the setting, you’ll be able to connect to all 4G LTE frequencies in the United States. Specifically, the Flare Kit will support major cellular carriers such as AT&T, Verizon, Sprint, and T-Mobile for your voice, text, and data needs. 

At any one time, up to eight people can use the booster and increase their respective signals. To increase or decrease signal strength, you can make manual gain adjustments to boost a particular wireless band.

Unlike most networking equipment, the Flare Kit is equally functional as it is sleek. The booster’s plastic shell adds a clean look that makes it inconspicuous, whether on a bookshelf or in a corner. On the other hand, the same can’t be said for the Flare Kit’s outdoor omnidirectional antenna. Although designed to be functional over all else, it doesn’t take away from the overall look of the booster. Once activating the Flare Kit, users have praised the considerable reduction in dropped and missed calls.

Coverage Size: Up to 2,500 square feet | Compatible Carriers: All North American carriers | Compatible Devices: 4G, 5G

"With a strong incoming signal, the SureCall Flare is billed to deliver up to 2,500 square feet of coverage from the booster. In our 1,800 square-foot house, coverage held up." — Hayley Prokos, Product Tester

Best for Medium Spaces: SureCall Fusion4Home Yagi/Whip Kit

What We Like
  • Suitable for medium-sized homes and offices

  • Clear and consistent signal boosting

  • Sturdy, durable design

What We Don't Like
  • Not suitable for large outdoor spaces or homes

  • Expensive

SureCall’s Fusion4Home Yagi/Whip Kit shares most of the Flare Kit’s notable characteristics. The Yagi/Whip Kit offers a clear and consistent signal across 4G LTE networks, boosting your signal for calling, texting, and data on Verizon, AT&T, Sprint, and more. Not only will you have fewer dropped calls and fewer texts not getting through, but you’ll also reduce waiting for Netflix or your favorite podcast to buffer.

Unlike the Flare Kit, the Fusion4Home Kit covers an additional 500 square feet, providing a range of 3,000 total square feet for a medium-sized home or office. The added square footage will cost you, however, as this booster will set you back anywhere from $400 to $500.

The Fusion4Home Kit is equipped with two different antennas for accuracy. For example, the outdoor directional Yagi antenna provides hyper-precise signal grabbing, while the indoor Whip antenna transmits the signal inside. To connect and power up the booster, SureCell incorporated a 50-foot RG-6 coax cable and an AC power supply. 

The Fusion4Home Kit was created to be efficient and long-lasting considering its sturdy metal design. The booster’s construction collects the outside signal via the Yagi antenna and sends it inside to the Whip. When you need a strong signal sent out, the design also works in reverse. The Fusion4Home Kit funnels data through the Whip, out to the Yagi, and back to the cell tower to send a signal out. For extra support, the booster comes with a three-year manufacturer’s warranty if something goes wrong.

Coverage Size: Up to 3,000 square feet | Compatible Carriers: All North American carriers | Compatible Devices: 3G, 4G, 5G

"Coverage largely depends on the signal received from the outdoor Yagi antenna, which is to be aimed in the direction of a cellular tower up to 30 miles away." — Hayley Prokos, Product Tester

Best 5G: ORPEY 5G Cell Phone Signal Booster for Home and Office

What We Like
  • Supports 5G networks

  • Automatic gain control

  • 5-year warranty

What We Don't Like
  • Newer, less-established brand

Although OPREY isn’t the most recognized brand on this list, the company offers something that most other companies don’t provide: OPREY’S signal booster can support 5G signals. More and more carriers across the world are rolling out 5G networks, and it’s evident more and more phones are supporting 5G.

To upgrade such signal strength, OPREY designed the perfect solution to boost areas of weak signal strength not only for 5G signals but also for 3G and 4G LTE signals. The booster can amplify signals on the largest U.S. networks including Verizon, AT&T, T-Mobile, and US Cellular.

The bands the boosters operate on are 2/4/5/12/13/17/66, so you’re guaranteed to have faster data speeds and clearer voice calls. Altering the 5G booster to your needs is seamless as it has automatic gain control. With this control, the booster can detect an incoming signal and adjust accordingly for superior performance. 

Potential buyers may be weary since OPREY isn’t that well known among cell phone signal boosters. However, the booster’s FCC and IC certifications may settle your nerves. If you’re still on the fence about OPREY’s 5G booster, you may get some comfort in knowing that it comes with a 5-year manufacturer’s warranty.

Coverage Size: Up to 5,500 square feet | Compatible Carriers: All U.S. carriers | Compatible Devices: 3G, 4G, 5G

Best Multi-Purpose: weBoost Signal 4G M2M Direct-Connect Kit

What We Like
  • Bypass failover feature

  • Modest price tag

  • Attractive, small, resilient design

What We Don't Like
  • Inconsistent performance

Not everyone is trying to boost the signal for their cell phones. Some people want an improved signal strength to be directed to other devices such as routers, hotspots, and modems. The weBoost Signal 4G M2M Direct-Connect kit, the earliest five-band direct-connect booster introduced to the market, is designed for those needing a connection to devices other than phones.

For roughly $300, the M2M Direct-Connect Kit, which is compatible with all U.S. wireless carriers, advances 3G or 4G LTE signal before directing it to another device. One of the most impressive features of the direct-connect signal booster is the passive RF bypass failure. If power is lost, the M2M Direct-Connect Kit activates to bypass the amplifier. In turn, the booster’s external antenna can preserve a connection to the receiving device. This feature is ideal for devices such as gates or security equipment.

weBoost's design of the M2M Direct-Connect Kit makes it easy to place within various settings. For instance, the compact form provides for the booster to fit discreetly in a closet or room and the rugged design ensures its contents are thoroughly protected. Although the booster looks appealing, users have complained that the signal remained unimpressive.

Best for Vehicle: weBoost Drive Reach Vehicle Cell Phone Signal Booster

What We Like
  • Portability, great for travelers

  • 50dB of gain

  • Uplink and downlink power

What We Don't Like
  • Limited phone placement to be effective

  • Pricey

There’s nothing worse than being on the road and hitting an area with poor cellular service or with no cellular service at all.

Additionally, weBoost greatly enhanced its uplink and downlink power from the Drive 46-X. Specifically, uplink power increased by 5bDm, and downlink power increased to more than 5bDm on each band. Even with the perks, for the booster to be limited to your vehicle, the $500 price tag may seem excessive.

Before you start your road trip, you won’t have to take too much time to set up your Drive Reach Booster. The kit comes with the booster, a magnetic antenna, a slim, low-profile antenna, and a power supply rapid charge USB-A port. For non-steel vehicles, the included special mounting equipment makes the Drive Reach easy to install. Overall, the booster takes only minutes to install, even without any tools.

FAQs

What is a signal booster and do you need one?
The FCC defines a signal booster as "devices that can help cell phone users improve their coverage in areas where they do not get a good signal." In other words, if you live in a rural area, or really anywhere with spotty 3G or 4G coverage, signal boosters can help fill that gap. These boosters can also extend network coverage into dead zones like tunnels or subways.

Can a signal booster interfere with other wireless networks?
Older signal boosters had a tendency to disrupt conflicting wireless signals, including the signals that handled emergency and 911 calls. However, a 2014 ruling by the FCC improved cell phone signal booster designs so they won't interfere with other wireless networks. While modern signal boosters have largely eliminated this problem, there is still a slim chance that it could interfere with existing signals.

Do you need to register your signal booster with the FCC or your wireless provider?
In short, yes. All modern signal boosters come packaged with labels provided by the FCC stating very clearly that you must register this device with your wireless provider. These labels will have a series of guidelines that must be adhered to in order to be within the legal statutes for the FCC.

What to Look For in a Cell Phone Signal Booster

Wireless vs. Cradle

Not all cell phone signal boosters are wireless. Some boosters actually use a cradle. With a wireless model, you’ll likely pay more than if you purchased a cell phone signal booster. Conversely, wireless models are capable of providing a stronger signal to multiple devices at once. Cradle signal boosters will only amplify the signal to one connected phone but will be easier on your pockets.

Band Coverage

Cell phone carriers, small and large, use a number of bands with different frequencies in providing cellular service to customers. With distinct bands and various frequencies, you need a booster that can sustain your particular cellular provider. The best cell phone signal boosters cover five bands in addition to 4G. Depending on your carrier and phone, it’s acceptable to select a signal booster with less coverage as long as the bands align to provide the requisite coverage.

Signal Strength

There are cell phone signal boosters on the market with both high-gain and low-gain antennas. Look for a booster with a high-gain antenna. With a high-gain antenna, you’ll want at least 5dBi if you live in a rural area without nearby cell towers. That said, if you live in a more urban area, your signal will likely be obstructed by terrain or builders. City dwellers will be satisfied with a lower-gain antenna.
