The Best Cell Phone Boosters for 2023

Especially if you are working from home, cellular dead zones aren’t just annoying, they’re mission-critical. If you have a weak signal in your home or none at all, a booster can help.

With that in mind, these are the best boosters for homes, apartments, cars, and anywhere else you might need better coverage. Below these picks, we cover everything you need to know before you purchase.

Deeper Dive: Our Top Tested Picks

SureCall Flare 3.0

Best for Homes

Why We Picked It

The SureCall Flare 3.0 is affordable, supports AT&T, T-Mobile, and Verizon, and combines a directional outdoor antenna with an omnidirectional indoor antenna. That means you can fiddle with the outside antenna to get the strongest possible signal, place the inside antenna anywhere you want, and still get coverage. It worked across three indoor rooms in our tests.

Who It’s For

This signal booster is ideal if you are looking to improve cell coverage in a small-to-medium-size house. It’s also quite easy to configure, which adds to its appeal.


  • Simple setup
  • Flexible placement
  • Boosts multiple carriers


  • Doesn’t boost T-Mobile bands 41 and 71

weBoost Drive Sleek

Best for Cars

Why We Picked It

The weBoost Drive Sleek offers an excellent, secure cradle that fits pretty much any phone, while the USB-A port on its power adapter ensures you can keep your device charged. In testing, we got about a 17-18dB improvement on T-Mobile and Verizon, which was enough to keep our in-car navigation going for that extra mile we needed.

Who It’s For

This is for road warriors who often find themselves in places with a spotty cell signal. It helps keep your GPS going for your entire journey and might prove invaluable if you ever need to place a call from a remote spot.


  • Improves signal on all carriers
  • Secure phone cradle
  • Easy to use


  • Only boosts one device
  • No band 41 or 71 support

weBoost Home Studio

Best for Small Spaces

Why We Picked It

The weBoost Home Studio is a two-piece booster with a particularly small, low-key indoor emitter, so it won’t crowd an already cluttered room. Like other weBoost products, it relies on a directional antenna you mount on a pole or roof outside to capture the best possible signal. Within the room it covers, its boosting potential is about the same as the larger SureCall Flare 3.0. But because it’s compact, it offers a bit less range than the Flare and much less coverage than a whole-home system like the weBoost Home Multiroom.

Who It’s For

Apartment dwellers should appreciate this booster because it can cover a moderately sized room in cellular signal. It also conveniently works with all the major US carriers.


  • Quick to install
  • Directional antenna is good at capturing signal
  • Small emitter is easy to place


  • Emitter covers two rooms at most
  • No built-in signal strength indicator

Cel-Fi Go X

Best for Large Homes or Very Weak Signals

Why We Picked It

Cel-Fi’s devices can get you 100dB of signal improvement because they boost the frequencies of only one carrier. Just keep in mind that its premier Go+/Go X home boosters cost much more than other consumer models and that this approach means you can’t switch carriers without switching your booster.

Who It’s For

If you need more of a boost than most consumer models offer (around 70dB of improvement), you should check out Cel-Fi’s specialty products. That extra bit of signal can make for a massive improvement, especially in rural areas.

HiBoost 15K Smart Link

Best for Large Areas

Why We Picked It

Most consumer signal boosters cover a few thousand square feet at most, but the HiBoost 15K Smart Link covers several times that amount. HiBoost’s devices also have a unique and cool feature: LCDs on the front that show signal strength for each of the bands they cover. Keep in mind that you’re probably going to want to use a splitter and additional panel antennas for a large home installation—one panel won’t cut it for 15,000 square feet.

Who It’s For

If cost isn’t a concern and you need to cover an extremely large space, you won’t find a more suitable consumer option than the HiBoost 15K. If you’re just looking to get cellular connectivity in a traditionally sized home, however, the SureCall Flare 3.0 above is a more reasonable choice.

SureCall Fusion2Go 3.0 RV

Best for RVs

Why We Picked It

RV boosters are a sort of hybrid between car boosters and in-home boosters. SureCall’s Fusion2Go 3.0 RV, for instance, uses an omnidirectional outdoor antenna—useful because your RV is always moving around—and offers two antenna options inside. It works with Verizon, AT&T, and T-Mobile, so you can pick it up no matter which carrier you prefer.

Who It’s For

Although this model isn’t as powerful as a home booster (it offers just 50dB of gain), it’s still better than regular car boosters. RV owners just need to make sure to place the indoor and outdoor components far enough away from each other and in the proper direction.

WeBoost Installed Home Complete

Best for Technophobes

Why We Picked It

The WeBoost Installed Home Complete solution gets you the same 72dB of signal improvement as most other boosters, but with the guarantee of absolutely optimal indoor and antenna placement—after all, WeBoost installs everything for you.

Who It’s For

If the prospect of DIY work scares you, WeBoost’s professional installation package might be worth the hefty price. It’s also suitable if you just want to ensure the best possible performance.

Buying Guide: The Best Cell Phone Boosters for 2023

What Are the Best Cell Phone Booster Brands?

Booster manufacturers have to use various tricks to detect the best signal from surrounding towers and then amplify them without messing up the carriers’ systems. That’s why you need to stick with boosters primarily from the big four companies: Cel-Fi, HiBoost, SureCall, and weBoost (we also include one from Wilson for a special use case you can read about below). Cheaper boosters available from Amazon often aren’t FCC-certified, which means they can cause trouble with surrounding cell sites and networks.

Do Cell Phone Boosters Really Work?

Boosters help the most when you have a weak signal, not when there’s none at all. Whereas your phone shows bars, wireless industry folks measure signal in -dBm. A number higher than about -90dBm (like -80 or -70) is a strong signal. Anything below -110dBm is definitely weak, and you might not hold onto any signal below -120dBm. Services like CellMapper(Opens in a new window) can show you the signal you’re receiving on your phone.

If you’re hesitant to invest in a home booster and primarily need coverage to make phone calls, make sure to try out Wi-Fi calling. All of the major carriers support this feature, and you can often get better call performance over a connection to your Wi-Fi network.

How Do Cell Phone Boosters Work?

The basic principle behind signal boosters is simple: A big antenna is better than a small one. Instead of relying on the tiny antenna in your phone, they capture cellular signal using a large antenna in your window or outside your house (or car), pass that signal through a device that cleans and amplifies it, and send it out through a rebroadcaster inside your home.

Boosters generally have three main components: an external antenna that sits outside your home, a booster that cleans and amplifies the signal, and an antenna you keep inside your home. A coaxial cable connects them all.

Some of SureCall’s products combine booster and indoor antennae into one unit. That makes SureCall’s boosters easier to install and place, which is part of why the SureCall Flare 3.0 is our top pick for in-home boosters. But if you own a larger home and are willing to run some coax cable, you can greatly extend the boosters’ range with some splitters and several panel antennas. This can get complicated, so, at that point, you might want to get a professional installer to set the system up (especially to reduce interference between multiple, in-home antennas.)

Recently, weBoost came out with its first two-piece booster for small homes and apartments, the weBoost Home Studio. It’s small and convenient but only covers one or two rooms in your home.

Most boosters handle bands 2, 4, 5, 12, 13, 17, and 66. That includes base coverage bands for AT&T, T-Mobile, and Verizon. The important missing band is 71, T-Mobile’s 600MHz rural coverage band. Because it took a while for TV stations to get out of that band, the FCC hasn’t approved any consumer boosters for band 71. If you want to boost that band, you need to get an industrial booster such as the WilsonPro 710i or SureCall Force8.

Most home boosters also boost between 64 and 71dB of signal. Once again, that’s due to FCC regulations. If you need more of a boost than that, you need to move up to Cel-Fi’s single-carrier booster line, which can get to 100dB by boosting only the frequencies from one wireless carrier at a time.

The booster store Waveform has a comprehensive guide to how boosters work(Opens in a new window) on its site.

What Is the Best Cell Phone Booster for Cars?

Boosters for your car are similar to in-home boosters, with one exception: You can only get single-device, in-car cradle boosters. These are much less powerful than in-home boosters (the ones we tested boost by 23dB instead of between 65 and 75dB) but are less expensive, take seconds to install and remove, and don’t radiate beyond the cradle that grips your phone. We like the weBoost Drive Sleek as a single-device booster.

RV owners and people who need to boost multiple devices in a vehicle can get in-car boosters with small radiating antennas that can handle several devices. These can be tricky, though, because of how close the output antenna is to the input antenna.

How Do You Install a Cell Phone Booster?

You can install all retail cellular boosters by yourself without any drilling, although ideally, you should hide the cables against your baseboards. You also need to find the optimal antenna position outside your home.

Recommended by Our Editors

Both SureCall and weBoost have options that let you lean on a professional installer to handle the tricky bits like sticking the antenna on your roof and orienting it properly. SureCall works with Dish subsidiary OnTech(Opens in a new window) to install any of its boosters for an extra fee. weBoost has a specific product, the Installed Home Complete, which comes with OnTech installation. The installation costs $200 for the weBoost product (it varies for SureCall products) so whether it’s worth it depends on your budget and DIY ability.

Can You Boost 5G Signal?

Cellular boosters generally can’t boost the “good parts” of 5G networks. AT&T and Verizon carry a small amount of 5G on the old cellular bands 2 and 5. Boosters handle that, so a booster may summon you a 5G icon, but that signal doesn’t give you an experience that’s much different from 4G. The fastest 5G networks for AT&T, T-Mobile, and Verizon are currently on bands n41, n77, n260, and n261; no consumer boosters support those bands reliably.

There is a sneaky way around this. Although no powered boosters work with these bands, passive antennas can still improve signal on bands 41 and 71. They may only get you 10dB to 20dB of gain as opposed to 70dB, but that isn’t insignificant (and even just the fact that the antenna is outside can help).

If you are willing to take on a bit of an installation project, the Waveform’s Griddy parabolic antenna(Opens in a new window) and MIMO panel antennas(Opens in a new window) improve signal on the 5G band n77. Connecting an outdoor cellular antenna(Opens in a new window) to a Wi-Fi hotspot that has a TS9 connector, such as the Netgear Nighthawk M6, can also turn an outdoor cell signal into an indoor Wi-Fi signal.
