The 15 Best AT&T Signal Boosters for 2021

Best AT&T Signal Boosters

AT&T is second largest cellular carrier in the United States and provides comparable coverage and network speeds to Verizon Wireless.

Even though AT&T provides coverage throughout most of the United States, consumers and businesses can still have problems getting signal into buildings or to rural locations, which is where a cell phone signal booster for AT&T comes in.

A cell phone signal booster is designed to amplify weak existing cell signal and distribute it throughout a home, business or vehicle. It can bypass obstacles like concrete walls, energy efficient window tinting, metal roofs, etc., and broadcast quality signal wherever it's needed, so you get reliable phone calls and fast data speeds.

There are a lot of AT&T cell phone boosters to choose from, so how do you find the right one for your situation?

Our signal experts have done the hard work for you and have ranked the 15 best cell phone signal boosters that will solve your AT&T signal problems.

Here they are:

The 15 Best AT&T Cell Phone Boosters

1. Wilson Pro 70 Plus

$1,199.99

The Wilson Pro 70 Plus is the best multi-carrier signal booster for your home or business, which means that it will simultaneously solve your AT&T signal problems along with all of the other major cell carriers.

It has the maximum boosting power that is permitted by the FCC for multi-carrier signal boosters and will boost all strengths of outside cell signal. The Pro 70 Plus comes with everything that you need to get started boosting cell signal, including a bonus lightning protector kit, and has an LCD display to aid in troubleshooting and fine tuning the antenna placements. It also comes with an industry leading 3 year equipment warranty.

The WilsonPro 70 Plus will boost all of the networks for AT&T and the other major cell carriers, and is able to boost 5G, if deployed on one of the five supported frequency bands.

If you need better AT&T cell signal in your home or small business, then the Wilson Pro 70 Plus is one of our top recommendations.

2. Cel-Fi GO X Smart Signal Booster for AT&T

Starts at $999.99

The Cel-Fi GO X for AT&T is the next best signal booster that we recommend for solving your AT&T signal problems. There are so many great things about this signal booster that it really should be tied for first place.

The Cel-Fi GO X is a single carrier signal booster, which means that it will only boost the cell signal from one carrier, so it falls under a different set of FCC regulations than the multi-carrier signal boosters that we offer. Single carrier boosters are able to have a maximum boosting power of 100 dB of gain, compared to 72 dB for a multi-carrier booster, which equates to almost 1000x more boosting power.

For this reason alone, the GO X would be an attractive solution, but it goes far beyond that.

Unlike the other boosters we offer, the Cel-Fi GO X uses an app on your smartphone to do things like: configure the amplifier, see the stats on the strength and quality of the incoming cell signal, switch to boosting a different carrier, and to aim the outside antenna.

This makes the GO X by far the smartest signal booster solution that we offer. Plus, it can be configured with a multitude of outside and inside antenna options, so you can customize the GO X to meet your specific needs.

If you only need to boost AT&T in your home or office and want a powerful, smart signal booster, then we highly recommend the Cel-Fi GO X for AT&T.

3. SureCall Fusion2Go Max

$499.99

If you routinely travel through areas with weak AT&T signal, then the SureCall Fusion2GO Max signal booster for cars and trucks is the solution that you want.

The Fusion2Go Max pairs the most powerful multi-carrier mobile signal amplifier on the market with its newly patented Extended Range Technology (ERT) to create a vehicle signal booster that can be as far from the cell towers as possible and still have reliable calls and fast data.

The SureCall Fusion2Go Max will boost all of the networks for AT&T and the other major cell carriers, and is able to boost 5G, if deployed on one of the five supported frequency bands.

If you regularly travel in very rural areas and need reliable AT&T cell signal, then the SureCall Fusion2Go Max is best for you.

4. weBoost Home MultiRoom

$549.99

The weBoost Home MultiRoom solution is our bestselling midsize signal booster for homes. It has an improved aesthetic over traditional signal boosters, so it looks better installed in your home, and one of the most powerful uplink and downlink powers on the market, so you get more coverage even further from the cell towers.

In addition to the improved aesthetic of the inside components, the outside antenna has been redesigned to easily mount to a vent pipe on the top of your house, so you're not required to use an additional pole or mast to mount it (though it is recommended if possible). This makes the Home MultiRoom one of the easiest signal boosters to install in your home.

The weBoost Home MultiRoom will boost all of the networks for AT&T and the other major cell carriers, and is able to boost 5G, if deployed on one of the five supported frequency bands.

If you have a small to medium sized home and need a high quality, easy to install solution, then the weBoost Home MultiRoom signal booster is the best choice for you.

5. SureCall Flare 3.0

$379.99

The SureCall Flare 3.0 is the best entry level signal booster for homes and small businesses. It is priced very affordably, yet has a powerful amplifier and great components. We highly recommend it for anyone who has a smaller space to cover and are looking for the most value for their money.

Unlike most of the other signal booster options that we offer, the Flare 3.0 combines the amplifier and inside antenna into a single unit that sits inside on a table or desk and broadcasts boosted signal throughout that part of your home or business. The outside antenna is a high powered yagi directional to ensure that the system works well with even a weak outside signal.

The SureCall Flare is an easy to install, affordable solution for small homes and businesses. It has the same amplifier and inside antenna combination unit that the Flare 3.0 has, but includes an omnidirectional outside antenna instead of a yagi directional. This means that it's easier to install and does not require aiming, but also does not provide as much coverage as the Flare 3.0.

The SureCall Flare will boost all of the networks for AT&T and the other major cell carriers, and is able to boost 5G, if deployed on one of the five supported frequency bands.

If you need our most affordable, yet still high quality, signal booster solution for a small home or business, then the SureCall Flare is the right solution for you.

The SureCall Fusion4Home Yagi will boost all of the networks for AT&T and the other major cell carriers, and is able to boost 5G, if deployed on one of the five supported frequency bands.

If you don't need the aesthetics that the weBoost Home MultiRoom offers and want to great midsize system that is also a great value, then the SureCall Fusion4Home Yagi is a great option for you.

11. SureCall Fusion5s

Starts at $850.00

The SureCall Fusion5s is one of our best solutions for large homes and small businesses. It has the maximum boosting power that the FCC allows, offers multiple inside and outside antenna options, and is priced more affordably than its competitor, the Wilson Pro 70 Plus. It also has a stronger downlink power than the Pro 70 Plus, which means that you'll get more coverage inside of the home or business if you have a strong outside signal.

The SureCall Fusion5s will boost all of the networks for AT&T and the other major cell carriers, and is able to boost 5G, if deployed on one of the five supported frequency bands.

The Fusion5s does not come with a lightning protector or an LCD display on the amplifier, so that is your tradeoff for the money that you save, though the lightning protector can be purchased separately. If you're looking for a great signal booster system at an affordable price, then the SureCall Fusion5s is going to be the option for you.

12. SureCall Fusion2Go 3.0 4G RV

$449.99

The SureCall Fusion2Go 3.0 4G RV signal booster is our best option for getting better signal in your RV. It is classified as a mobile signal booster, so it can be used to get better signal while driving down the road as well as stopped, but that also means that the size of the boosted signal will be fairly small within the RV.

If you plan to use the signal booster to improve your data speeds for Internet browsing, then the small coverage area isn't a problem, and you just need to make sure your phone or hotspot is next to the inside antenna to ensure that fastest possible data. If you're primarily after better phone calls, then you'll want to make sure your phone is next to the inside antenna and then use bluetooth headphones to talk while you're moving around the RV.

Some RV owners only want better signal while parked, in which case they're able to use a more powerful signal booster, like the weBoost RV 65, which takes a few minutes to setup at your location, but should provide boosted signal throughout most, if not all, of the RV. The tradeoff is that you won't get boosted signal while driving with the RV 65.

The SureCall Fusion2Go 3.0 4G RV will boost all of the networks for AT&T and the other major cell carriers, and is able to boost 5G, if deployed on one of the five supported frequency bands.

If you want a solution that will provide you with quality signal miles after you would have lost it without a booster, and you're ok with a small inside coverage area, then the SureCall Fusion2Go 3.0 4G RV is the solution for you.

13. weBoost Drive Reach Marine

$749.99

If you need to boost cell signal while on the water, then the weBoost Drive Reach Marine kit is going to be the best solution for you. It uses a high powered marine antenna with the strongest mobile amplifier from weBoost to give you the best possible signal in your boat and extend your ability to receive cell signal by miles from the shore.

Since the booster is technically being used while in motion on the boat, it does fall under the mobile signal booster FCC guidelines, which means the size of the boosted signal coverage area that it creates on the boat is only a few feet from the inside antenna. In order to use the boosted signal and fast data speeds, you'll want your phones or mobile devices to be placed near the inside antenna at all times.

The weBoost Drive Reach Marine will boost all of the networks for AT&T and the other major cell carriers, and is able to boost 5G, if deployed on one of the five supported frequency bands.

If you need better cell signal and fast data speeds while on your boat, then the weBoost Drive Reach Marine is the best solution for you.

14. weBoost Drive Reach RV

$499.99

The weBoost Drive Reach RV signal booster is a great alternative to the Fusion2Go 3.0 4G RV booster. It offers a spring mount RV antenna instead of the standard omni and the option of either a desktop antenna or a separate panel inside antenna, rather than the whip antenna that is attached to the amplifier with the Fusion2Go solution.

You'll have greater installation flexibility and slightly more inside coverage with the Drive Reach RV, if you go with the more powerful inside panel antenna, and less chance of breaking off the outside antenna off because of the spring mount. The only major downside of this solution is that it's slightly more expensive than the Fusion2Go 3.0 4G RV.

The weBoost Drive Reach RV will boost all of the networks for AT&T and the other major cell carriers, and is able to boost 5G, if deployed on one of the five supported frequency bands.

If you need a dependable solution for your RV with greater installation flexibility and better performance, then the weBoost Drive Reach RV is the solution for you.

15. Cel-Fi QUATRA Hybrid DAS

The Cel-Fi QUATRA Hybrid DAS is the most powerful and intelligent solution for better AT&T signal in a large building. It is our #1 recommendation if you need a custom solution for your business, but it's #15 on our list because most people are not looking for an enterprise grade solution to their cell signal problems.

That said, if you need a solution that can scale to hundreds of thousands of square feet, includes enterprise monitoring, and has the ability to boost additional frequency bands as they're approved by the FCC, then the Cel-Fi QUATRA is definitely best solution for you.

All versions of the QUATRA will boost AT&T and one or all other carriers. No matter what your situation is, there is a Cel-Fi QUATRA solution for you.

If you need an enterprise solution for AT&T, then there is no better solution than the Cel-Fi QUATRA Hybrid DAS.

Do Cell Phone Signal Boosters Really Work?

One of the biggest questions that we get is "do cell phone signal boosters really work?". This is a reasonable question, especially with all of the scammy products that have been released in the past claiming to give you better signal.

The answer is yes, they absolutely do.

But you don't have to take our word for it, the FCC and the major cellular carriers have all independently tested every signal booster that is sold on the market today, and have not only approved them for use, but recommend them as a preferred solution for getting better cell signal in your home, office or vehicle.

What is an AT&T Signal Booster?

An AT&T signal booster (also known as an AT&T cell phone booster, AT&T cell signal booster, or AT&T signal booster) is a solution that receives an existing outside AT&T cell signal, boosts it, and distributes it throughout the area of your home, office, car, truck, RV or boat that needs better AT&T signal.

It uses an outside donor antenna to receive the existing signal, which is then passed over a cable to a signal amplifier and boosted significantly. The boosted signal is then passed over another cable to one or multiple inside antennas, which broadcast the boosted signal to the area that needs it most.

The system also works in reverse, so the signal is boosted as it's leaving your mobile device and broadcast much more powerfully to the distant cell towers.

Please note: an AT&T booster is not an AT&T microcell or AT&T network extender, which uses your broadband Internet to work instead of the existing outside cell signal.
