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 antennas 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.

Best Overall: SureCall Flare Cell Phone Signal Booster Kit

Surecall Flare Cell Phone Signal Booster Kit
What We Like
  • Works for modestly-sized homes and offices

  • Works with all 4G LTE frequencies

  • Supports up to eight simultaneous users

What We Don't Like
  • 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

Best for Medium Spaces: SureCall Fusion4Home Yagi/Whip Kit

What We Like
  • Works well for medium-sized homes

  • Clear and consistent signal boosting

  • Sturdy metal construction

What We Don't Like
  • 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

Best for Office: HiBoost Signal Booster for Office

What We Like
  • Good for office environments

  • Large range

  • Ability to fine tune max power

  • Customized settings and controls

What We Don't Like
  • Somewhat pricey

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.

Best for Multiple Rooms: weBoost Home Multiroom (470144) Cell Phone Signal Booster Kit

What We Like
  • Works on all major carriers

  • Reasonable price

  • Attractive design and wall mounting option

What We Don't Like
  • Needs to be placed in different locations, taking up power outlets

The weBoost Home Multiroom is another at-home solution to improve wireless signals, particularly in rural areas. This signal booster is designed for use in multi-room accommodation, enhancing signal strength in three large rooms or up to 5,000 square feet. That gives it a better indoor range than many competitors, and it works with voice, text, and data for all major U.S. mobile carriers. The company promises a 21dBm increase in uplink output power and a 12dBM increase in downlink output power, allowing you to better reach the closest cell phone towers. Unlike most other booster units, the setup isn't too bulky and there's a nice design and finish to the visible piece which you can wall mount. The one downside is that you need to set up two separate units in different locations which might be an issue in places with limited outlets.

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

The OPREY 5G Signal Booster may not be a well-known brand compared to the others on this list, but it does offer something the rest don't—it can boost 5G signals. With more carriers across the world rolling out 5G networks and more phones supporting 5G, the OPREY offers a solution for areas of weak signal strength. It works to boost 3G, 4G LTE, and 5G on all major US networks like Verizon, AT&T, T-Mobile, US Cellular, and others.

The bands it operates on are 2/4/5/12/13/17/66, giving you faster data speeds and improved voice calls. It has automatic gain control, letting it detect an incoming signal and adjust for better performance. Last, but not least, it's FCC and IC Certified and comes with a 5-year manufacturer warranty so you don't have to worry about buying from a little known brand.

Final Verdict

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.

What is a signal booster and do I 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. However, whether you need one or not will largely depend on where you live, but will be most useful in rural areas.

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 I need to register my signal booster with the FCC or my 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 - 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.
