7 Best Sprint Signal Boosters for Home, Office, and Car

Sprint may have some of the best value for unlimited plans, but if you're not getting any signal on your cell phone, even the cheapest plan isn't worth much if you can't make a call or stream a video.

That's why boosting your Sprint 3G & 4G signal becomes the best option.

Let's look at why you've got poor signal and what you can do about it.

The Problem: Why Your Sprint Service Needs Help

Cell phone signals are radio waves, the AM-FM kind. And like all wind and waves, they easily go in different directions without notice. Almost anything under the sun can change, absorb, and block your Sprint service. Here are top 5 reasons:

  • Cell tower distance: Physical distance and power transmission distance
  • Outside interference: Trees, hills, mountains, valleys, and tall structures.
  • Building material: Metal (especially metal!), glass, concrete, brick, radiant barrier, and other conductive material (electrical or magnetic).
  • Internal building obstructions: Thick walls, plaster, drywall, and other electrical devices & clutter, etc.
  • Even weather (yup): Rain, thunderstorms, solar flares, etc.

Any combination of these problems can drastically reduce your service.

Doesn't matter if you're in a rural or urban area, poor cell phone signal affects us all.

The Solution: Boost Your Sprint 3G & 4G LTE Signals

Everything changes with a cell phone signal booster.

A cell phone signal booster takes any existing 3G & 4G LTE signal and amplifies up to 32X and then rebroadcasts the boosted signal into the home, office, or car.

It's simple: more bars, better service.

  • Better Coverage: Think of a signal booster like a megaphone. It takes what you have and multiplies the performance.
  • Reliable Reception: No more dropped calls, spotty service, and low quality calls.
  • Consistent Service: Fast internet data, uploads, and downloads.

Sprint Signal Boosters: Your Guarantees

Our recommended signal boosters are very versatile:

  • Works for all Sprint & subsidiaries (Boost Mobile, Virgin Mobile, Open Mobile, Tello, TextNow etc.).
  • Future proof: Also boosts signal for AT&T, Verizon, T-Mobile and other major carriers.
  • Works for all phones & cellular devices.
  • Complete kits, easy to install.
  • No monthly fees, no need to connect to wifi.

Information Alert: Sprint's LTE (formerly known as Spark) uses three frequency bands to power their service: 800MHz, 1.9GHz, and 2.5GHz for fast data speeds. Unfortunately, 2.5GHz (Band 41) –also commonly called Sprint LTE Advanced– is not supported by our products at this time, while the rest of Sprint's 3G & 4G LTE are supported.

If your area is using Sprint LTE Advanced as the only means to connect to 4G LTE and that's all you're looking to boost (remember, it will boost 3G and other 4G LTE bands), then we do not recommend our booster at this time.

If you are unsure about your cell phone using Sprint LTE Advanced, please check out this list of cities or use Sprint's coverage map to find out if your area is using Sprint's LTE Advanced or 2.5 Ghz (Band 41)

For homes, whether you're in a remote rural area with an off-the-grid cabin or cottage or the big city with difficult-to-get-signal buildings, our recommended cell phone boosters get the job done. They'll extend your Sprint network signal with low-cost options for 1-2 rooms up to 7,500 sq ft coverage depending on your model and outside signal.

Our vehicle signal boosters work for cars, sedans, RVs, and even boats.

Enterprise Sprint signal boosters cover up to 100,000+ sq ft buildings, although it takes a dedicated team of installers and planners to get the absolute best service.

Why be a servant to the cell tower? Bring the cell tower inside your home! Below are our top recommendations.

Sprint Cell Phone Signal Booster For Home

Our Pick

  • Whole home coverage:
    Improves 4G LTE & 3G coverage up to 5,000 sq ft (most homes).
  • Most popular home booster:
    Trusted by hundreds of thousands of people across rural & urban America.
  • High-powered range: Up to +65 dB gain for 32X stronger signal.

The The weBoost Connect 4G has been the most recommended home cell phone repeater for nearly 5 years in a row for good reason. It's a dependable performer that covers most homes for better service.

The average home size in North America is around 2,500 sq ft. Under absolute best conditions, the Connect 4G covers up to 5,000 sq ft with great outside signal and an open-spaced layout home.

Real world results and customer reviews put it around 2,500 to 3,000 sq ft, a little less for rural areas.

Great option for most homes, small offices, farm houses, and buildings under 5,000 sq ft wide. If you're getting some spotty reception, we'd recommend to start with this first since this tends to be the Goldilocks or "just right" model.

  • FREE shipping, no minimum purchase.
  • 90 Day money back guarantee.
  • Lifetime support.


  • Whole home coverage:
    Improves 4G LTE & 3G coverage up to 7,500 sq ft (large buildings).
  • For Large Building Coverage:
    Trusted by hundreds of thousands of people across rural & urban America.
  • High-powered range: Up to +70 dB gain for 32X stronger signal.

Our Review:

The weBoost Connect 4G-X is absolutely the most powerful consumer line repeater you can get. With an additional +5 dB over the Connect 4G, it's roughly a shade over 3x more powerful.

Best case scenarios can expect coverage up to 7,500 sq ft. More likely results can at least expect 4,000-5,000 sq ft even with below average outside signal. Again, fringe zones can expect a little less.

If you have extremely poor signal (remote area) or need wide coverage for a building 5,000 sq ft and over like a warehouse, the weBoost Connect 4G-X is your new best friend.

  • FREE shipping, no minimum purchase.
  • 90 Day money back guarantee.
  • Lifetime support.


  • 1-2 room coverage:
    Improves 4G LTE & 3G coverage up to 1,500 sq ft.
  • High-powered range: Up to +60 dB gain for 32X stronger signal.

Our Review:

The weBoost Home 4G is a nice cheap option if you're on a budget and only need spot coverage.

Depending on the outside signal, you may get 1-2 room coverage under best conditions. But you're not here because of best conditions, so it's more realistic to say desktop to small room coverage (about 250 to 500 sq ft).

Most customers have told us they're much closer to the inside antenna than anticipated for better signal. Great option for single office, home office (SOHO) and small areas like cabins and apartments. Good starter kit if you have decent outside signal but doesn't cover the whole home and not a strong performer in rural areas with poor signal.

Sprint Cell Phone Signal Booster For Car

Our Pick

  • Boosts Voice, Text, 3G & 4G LTE Data
  • cd
  • For a multiple cell devices
  • Up to +50 dB Gain

Our Review:

The weBoost Drive 4G-M is the most popular & recommended car signal booster in North America.

A slim outside antenna picks up signal. An indiscreet inside antenna (usually Velcroed to the driver seat) broadcasts signal inside. You have to be about an arm's length to get the boosted signal, so it's best for your typical sedan, truck, or SUV.

Majority of customers in the city say they're getting at least 2 to 3 more bars. For off-the-grid areas, a few did say they have to be closer to the inside antenna than anticipated to get more bars and amplified signal. Boosts signal up to 4 devices.

Updated: The new & improved version of the weBoost Drive 4G-M features a stronger inside antenna with +5.1 dB gain compared to the +4.3 dB gain of the previous model (# 470108). Links have been updated to point to the new version.

Only at
  • FREE shipping, no minimum purchase.
  • 90 Day money back guarantee.
  • Lifetime support.


  • Boosts Voice, Text Message, 3G & 4G LTE Data
  • For multiple cell devices
  • Up to +50 dB Gain
  • Pro Model: 60% More reach from and to cell tower

Our Review:

The weBoost Drive 4G-X is the most powerful car cell phone repeater in the market capable of boosting up to 4 cellular devices.

It features up to +3 dB gain compared to other car repeaters on the uplink, which technically translates to 2x the power increase or about 30-60% more reach to the cell tower in real-world results.

We recommend the Drive 4G-X primarily to those who live or drive frequently in rural areas, where distance to and from cell towers is the biggest problem.

People in urban areas may get away with a less expensive model, but for people who live off the grid, this is the first unit we recommend.

Only at
  • FREE shipping, no minimum purchase.
  • 90 Day money back guarantee.
  • Lifetime support.


  • Boosts Voice, Text Messages, 3G & 4G LTE Data
  • For a single smartphone
  • Up to +23 dB Gain

Our Review:

The weBoost Drive Sleek is about price and performance for the single user.

It uses a magnetic vent mount and when paired with a bluetooth headset, it really shines for regular talk & text and hands-free navigation.

Smartphone has to be in the cradle to get maximum signal boost. New design allows for wider smartphones and small tablets.

Is a Sprint Signal Booster the same thing as a Sprint Magic Box?

No, they're completely different products, although some similarities in performance.

A Sprint Signal Booster is a repeater that takes incoming weak 3G & 4G LTE signal (2.5 GHz excluded), amplifies it, and rebroadcasts stronger 3G & 4G LTE inside your home. Think of it like a megaphone. It'll boost talk, text, and data.

A Sprint Magic Box is a small cell system that relays to Sprint's 1.9 GHz and 2.5 GHz 4G LTE services. It delivers faster 4G speed and coverage indoors. Think of it like a bridge. It'll only boost data.

Which is better: Sprint Signal Booster or Sprint Magic Box?

It depends.

If you're a qualified customer (aka longtime customer) in an area with poor signal that does provide 1.9 GHz and 2.5 GHz service, then go with the Sprint Magic Box since it's free if you qualify.

See this list of cities or use Sprint's coverage map to see if your area is covered.

But please remember it only covers 4G which is data. Talk and text are still on 3G, which the Magic Box does not improve, unless you're using Wi-Fi calling.

If you're not a qualified customer, don't have 1.9 GHz and 2.5 Ghz service in your area, care more about talk & text than internet data, then go with a Sprint Signal Booster. It's compatible with other carriers and allows for future upgrades.A

Most likely, people in urban areas will have access to the Magic Box while rural areas won't. A Sprint signal booster is made for rural areas.

One More Thing You Need to Know About the Sprint Magic Box

One description you may hear is how a Magic Box "densifies Sprint's network." What does that exactly mean? Well, you know how people in neighborhood fight carrier about putting cell towers and cell sites near them?

Guess what? That's exactly what they're doing, except, they're putting it inside your home. Which means your Magic Box is also servicing other Sprint customers and businesses.

So what's the big deal?

Generally, the city charges hundreds or thousands a year to lease their property (traffic lights, street lights, other utility poles, etc.) for carriers to place their cell service equipment. You're doing it for free. Just saying...

Will a Sprint Signal Booster also improve my Sprint hotspot device?


Sprint mobile hotspot routers use 3G & 4G LTE signals, and that's what signal boosters do: enhance 3G & 4G LTE signal (2.5 GHz excluded)!

From the Sprint Drive to Franklin to other 4G routers, it'll get better signal and speeds, especially if the Sprint 4G router has an external antenna port that can directly connect to the Sprint signal booster.

Will a Sprint Signal Booster work with my Sprint phone?

Yes, yes, and yes.

Whether it's an iPhone, iPad, Galaxy, Pixel, or any phone, if it's working on the Sprint network (2.5 GHz excluded), then a signal booster will also improve reception to your phone.

What if I switch carriers in the future?

Our Sprint signal boosters from Wilson Electronics (weBoost & WilsonPro) are multi-carrier systems. This means they are also compatible with AT&T, Verizon, T-Mobile, US Cellular, and other major and local carriers.

They are future-proof!

What about Sprint 5G service?

Yeah... about that.

The 5G standard has not been officially set by the 3GPP. Therefore carriers like Verizon and AT&T are pre-building our their 5G services by upgrading their current 4G LTE and giving it names like 5G Evolution, First on 5G, 5G+,etc.

But no, it's not the real 5G. It's pre-5G, fake 5G– it's literally 4G LTE on steroids.

The real 5G should launch by the end of 2020.

Will 5G make my Sprint signal booster obsolete?


4G LTE is still being built out across North America. If fact, 4G LTE is the backbone of the nation's wireless service. It's not going anywhere anytime soon, AND it's getting faster.

4G LTE is expected to peak in 2030-2035. So...come back in a decade and ask the same question and we might hava a different answer by then.
