The best cell phone signal boosters help banish areas of weak signal by supporting calls and data from your mobile carrier. They're helpful for homes, office buildings, and even cars in areas where signal just might not reach. They work by using larger and additional antennaes than the one you get on your phone or other mobile devices. One thing to keep in mind is that a signal booster helps when the signal is weak, but it won't work in a dead zone where there's no signal at all.
Our top choice is the weBoost Home 4G Cell Phone Signal Booster at eBay. It comes from a reputable brand name in the industry, supports 1,500 square foot spaces, and can boost 4G LTE signals from all major U.S. carriers, including Verizon, AT&T, Sprint, T-Mobile, and others.
If your cell service isn't cutting it, that might also be something worth changing. Take a look at our list of the best cell phone plans to see if there's a better option to meet your needs. Otherwise, read on to see the best cell phone signal boosters.
Reputable brand name
Works for apartments and small homes
Boosts both 4G and 3G for all US carriers
Won't work for bigger spaces
weBoost is sort of the biggest name in the game when it comes to cell phone signal boosters, so it was a natural choice for our top spot here. The 4G Booster for 1,500-square-foot spaces is the classic signal booster for anyone looking to step up their signal in a few rooms (perfect for home offices or apartments). It offers the most basic of functions since it just boosts the already existent 4G LTE signal in the spaces, and it’s compatible with all major U.S. carriers, including Verizon, AT&T, Sprint, Straight Talk, and more. Our reviewer did note that she had mixed results on Verizon though.
They claim it boosts the signal, both 4G and 3G, up to 32 times as strong as what it was before, which means fewer dropped calls and fewer spinning loading wheels. An added side benefit is the extension of battery life, which weBoost states you could get up to two additional hours of talk time just because your phone isn’t hunting for one or two bars of signal.
The unit is also optimized for audio and video streams, which prevents drops on your entertainment. Just install the outdoor antenna to pull in the existing signal, connect the coax cable to the indoor receiver, and connect an indoor antenna for further stability inside. It’s as simple as that, and then you’re ready to rock.
"The weBoost Home 4G Cell Phone Signal Booster performed within the parameters that it advertises, though it comes at a steeper cost than some of its competitors." — Hayley Prokos, Product Tester
Works for modestly-sized homes and offices
Works with all 4G LTE frequencies
Supports up to eight simultaneous users
Won't work for large offices or big homes
When not having a cell phone signal just won’t do, turn to the SureCall Flare Cell Phone Signal Booster Kit. Capable of covering up to 2,500 square feet in a home or office, it’s a smart solution to an annoying problem. Compatible with all 4G LTE frequencies in the US, the booster will support AT&T, Verizon, Sprint, and T-Mobile. Coverage for voice and text will benefit from the signal boost as much as data does. Up to eight simultaneous users are able to connect and utilize the increased signal at a time. Manual gain adjustments are utilized to specifically boost a wireless band for amplification.
While most networking equipment tends to be more function than design, the Flare is a combination of both. The plastic shell adds a clean look that fits in easily on a bookshelf or any corner in an office. The outdoor omnidirectional antenna, on the other hand, is designed to be functional over all else. Once activated, online reviews praise the significant reduction in dropped and missed calls.
"The SureCall Flare Cell Phone Signal Booster Kit performed well within the parameters that it advertises and is available at a budget-friendly price (at least comparatively speaking)." — Hayley Prokos, Product Tester
Large range for outdoor spaces
32x stronger signal for all major carriers
Can optimize boosting based off signal conditions
This weBoost 4G-X is an insane workhorse that offers a range so massive that it’ll work for large homes, outdoor boosting, and even a small office space. So, if you’re looking for something to support your startup business, this could be the unit. Just like the smaller range units, it offers up to 32x stronger cell signal for all major providers, including Verizon, AT&T, Sprint, T Mobile, US Cellular, Straight Talk, and more. It’ll work great for all major cellular-connected devices, from phones to tablets to hot spots, even to data-connected notebooks.
The range offers extension is up to 7,500 square feet and it connects via the same method of an outdoor antenna, daisy-chained through the coax cable, to the indoor receiver along with an indoor antenna. This premium, large-space model also offers a unique additional bit of technology called an Automatic Gain Setting that reads the signal condition in and around the building, determines how strong it is, and then electronically optimizes the boost needed. It all provides the best, most stable talk, text, and data environment for your business.
"This kit offers a whopping 7,500 square feet of coverage, outperforming many other boosters on the market." — Hayley Prokos, Product Tester
Works well for medium-sized homes
Clear and consistent signal boosting
Sturdy metal construction
Won't work for large outdoor spaces or homes
Covering up to 3,000 square feet, this SureCall Yagi/Whip package is perfect for a medium-sized home. It offers you a clear and consistent signal, boosting from the service you already have, for up to 4G LTE, plus calling and texting on Verizon, AT&T, Sprint, and more. This will all contribute to less dropped calls, fewer texts not getting through, and less waiting for Netflix buffering.
The kit contains an outdoor directional yagi antenna for hyper-accurate signal grabbing, an indoor whip antenna for transmitting it inside, a 50-foot RG-6 coax cable to connect it up, and an AC power supply. The units are built with a sturdy metal construction and have a three-year manufacturer’s warranty just in case something does go wrong. It works by collecting the outside signal via the Yagi antenna and sends it inside to the Whip. When you want a strong signal sent out, it works in the reverse, funneling your data through the Whip, out to the Yagi, and back to the cell tower.
"The SureCall Yagi/Whip package is our go-to pick for a medium-sized home, as it offers, in standard conditions, a satisfactory amount of signal over a pretty extensive area of 3,000 square feet." — Hayley Prokos, Product Tester
Omnidirectional antenna to pull signal
Huge 20,000 square foot range
Automatic dB and gain optimization
The SureCall Fusion 5X is the cream of the crop (and has the price tag to match). It comes with a proprietary omnidirectional antenna that goes outside and pulls signal from all directions, so there will be no shortage of signal to boost. It also comes with four internal panel extenders that carry the signal inside the home. The range is a completely head-spinning 20,000 square feet, so you’d be able to power a full factory or a super large estate. It supports talk, text and 4G LTE from the major carriers including Verizon, AT&T, T Mobile and more. On top of that, the receivers inside are SureCall’s first units that don’t have knobs or explicit controls. That’s because the dB and gain optimization happens automatically (you don’t need to figure out the right signal level to work with your space because the device will read the signal and extend it the correct amount on its own).
Good for office environments
Ability to fine tune max power
Customized settings and controls
If you need signal boosting in a device-heavy office environment, one of your best options is the HiBoost Signal Booster. Designed specifically for offices, the HiBoost works with all cell phone carriers in the US and Canada, amplifying 4G LTE, 3G, and 2G signals. It can strengthen the signal to any cellular device, improve data speed, and reduce dropped calls. The range varies between 7,000 square feet to 15,000 square feet depending on outdoor conditions and the distance you are from a tower.
To help you get the strongest signal, there's an app and LCD panel so you can fine-tune the power and see real-time data of the booster's activities. The signal booster is FCC and IC certified and comes with a three-year warranty. There's also U.S. based tech support if you have questions that need to be answered.
The best cell phone signal booster to get for most people is the weBoost Home 4G Cell Phone Signal Booster (view on eBay). it works well for spaces around 1,500 square feet, making it ideal for apartments and small homes. It's compatible with all major carriers to boost 4G LTE and 3G signals. For a longer-range option, we like the SureCallFlare Cell Phone Signal Booster Kit (view on Amazon). It has a reasonably attractive design, a 2,500 square foot range, and works better for portable use.
Hayley Prokos has been writing for Lifewire since 2019 and has reviewed a number of products from cell phone signal boosters to MacBook cases and projectors. She praised the weBoost Home for its strong signal boosting abilities and reasonable price.
Wireless vs. cradle - Some cell phone boosters are wireless, and others use a cradle. Wireless models tend to be more expensive and are capable of providing a stronger signal to multiple devices at once, while cradle signal boosters only amplify the signal to one connected phone.
Band coverage - Cell phone carriers use a number of bands with different frequencies, and you need to choose a booster that’s compatible with yours. The best cell phone signal boosters cover five bands in addition to 4G, but it’s okay to go with less coverage as long as the bands used by your carrier and phone are covered.
Signal strength - Cell phone boosters are available with both high-gain and low-gain antennas. Look for a booster with a high-gain antenna that’s at least 5dBi if you live in a rural area with no nearby cell towers, and a lower-gain antenna if the signal is obstructed by terrain or buildings.
