Receiving a decent cell signal on your cell phone can be a challenging task in many cases. Several customers experience dropped calls or minimal 3G/4G LTE connectivity while indoors.

This could be simply due to the area you live in or the fact that your home/office has several obstructions on its path. Blockages can be anything ranging from buildings, mountains, metal rods, even billboards at times. Then there’s the concern of your carrier not having enough cell towers around to provide enough coverage. Customers who are driving may also experience drops in cell signals.

Thankfully, the industry has come up with range extenders or phone signal boosters for your phone and all the devices around you, helping you get the best signal strength every single time. A lot also depends on the range offered by the cell booster which is usually measured in square footage (sq ft). For example, a 2,000 sq ft cell booster should be adequate for a medium sized home or for two rooms.

Given that AT&T is one of the most popular carriers in the U.S. today, it goes without saying that a lot of customers are trying to get a capable signal booster to enhance AT&T signals.

Unfortunately, the options are several, which means that the choice can be somewhat confusing. This is why we’ve decided to talk about some of the best cell phone boosters you can get for your AT&T cellular network. We will also go through some of the best cell phone boosters for your car or truck.

Let’s have a look.

AT&T Cell Phone Booster


1. Hiboost Signal Booster

The HiBoost Signal Booster comes with a wide range of features under the hood to make it one of the best signal boosters for home/office right now. It consists of a standard antenna that has to be kept outside (preferably on your roof) and is accompanied by an indoor antenna to extend the range. This booster supports multiple users, so it’s perfect to be used by the entire family.

This signal booster comes with a range of up to 2,000 sq ft which makes this a perfect option for small to medium-sized homes. However, customers have to be mindful about the positioning of the indoor antenna as any obstructions on its path can slow the network speeds significantly. Provided AT&T does provide coverage in your area, this signal booster can significantly enhance indoor coverage while on 3G/4G LTE networks.

Further, having a decent signal strength indoors is also expected to reduce the number of dropped calls by a big margin. The best part here is the support for HiBoost’s mobile app (available for Android and iOS platforms). This app can help you with the installation process while also providing signal related information in real-time. The manufacturer offers 3 years of warranty with this product, making this one of the best signal boosters out there.

2. weBoost Home Room

One of the best offerings that show up when you search for a cell phone signal booster is the weBoost Home Room. This is probably because the Home Room is one of the most comprehensive cell boosters currently selling the market. In terms of features, the weBoost Home Room comes with two antennas meant for indoor and outside use respectively.

The best aspect of the outside antenna is that it can be mounted to railings on your porch, saving you the trouble of heading over to the roof. It’s also worth pointing out that this signal booster offers a tool-free installation overall. Thanks to the indoor antenna, the Home Room can offer a boosted signal at up to 2,000 square feet (sq ft) as long as there are no blockages on its path.

As you would expect, this signal booster supports a wide range of networks in addition to AT&T which allows multiple users to benefit from its features. The company mentions that this device offers a maximum gain of 60dB. In addition to supporting standard 3G/4G LTE networks, the Home Room also comes with support for AT&T’s 5G networks.

3. PHONELEX Cell Signal Amplifier

This product is somewhat unique with its design, though this is not necessarily a bad thing. This device can offer a boosted signal using a high-quality outside antenna while the indoor antenna is designed in a way to provide a 360-degree range within your home/office. Speaking of which, this device can offer a boosted signal for up to 2,000 sq ft, which basically means it can be used in your home or office.

This is also one of the easier signal boosters to install and the manufacturer offers all the necessary tools to help with the process. It shouldn’t take more than an hour even if you’re not accustomed to installing antennas. However, customers will have to ensure that the outdoor antenna which mostly goes on the roof is facing the nearest cell signal tower.

The manufacturer specifies that this product offers improved 3G/4G LTE speeds in addition to improving indoor call quality. However, customers must be aware that a boosted signal usually requires at least 1 or 2 bars of coverage on your cellphone. This range extender doesn’t come with a display and only comes with a single LED indicator for power.

4. BOSURU Phone Signal Extender

This is pretty similar to the signal booster we discussed above, though there are some differences on board. First and foremost, this extender uses a whip antenna for improved signal strength indoors. Whip antennas are extremely easy to install, particularly in comparison to contemporary indoor cell booster antennas. This signal extender supports AT&T’s 3G/4G LTE networks with the ability to improve call quality significantly.

As far as installation is concerned, the manufacturer mentions that setting this up will not need prior experience. The outside antenna can be placed on your roof or any alternative open space. Since this is a directional antenna, it is recommended to make sure it’s facing the nearest cell signal tower.

This signal booster can be used for an area of 1,500 to 2,000 square feet (sq ft) while it also comes with the ability to boost cellular signals on multiple devices in its vicinity. The cable required to establish a connection between the antennas is provided with the product. The company mentions that this product is suited to be used on AT&T’s 700 MHz cellular networks (bands 12 and 17).

5. Cell Booster by Obdator

This is a lightweight and easy to install cell signal booster that comes with a pretty decent set of features. The first thing that customers will notice with this product is the fact that it’s extremely easy to install. All the markings are well laid out on the device, meaning the installation won’t take more than an hour. It consists of an indoor whip antenna, while the outdoor unit is a panel antenna that can be wall-mounted if necessary.

It comes with a maximum range of 2,000 sq ft, which also happens to be one of the most sought after range for signal boosters, especially if you’re looking to boost signals in just one or two rooms. It supports a wide range of networks in addition to AT&T which means it can be used to improve cell signal quality on practically any cellular device within its range.

Depending on the proximity of the cell tower to your home, this booster can offer 1-2 more bars than usual. This means that customers who get 3-4 bars without needing an amplifier will likely see signal strength reaching full capacity. This is as simple as signal boosters come, and we highly recommend the product based on this facet alone. The fact that it also works pretty well overall is certainly the best part.

6. FUSTAR Signal Booster

This is an excellent 700 MHz tri-band signal booster with support for bands 12/13/17, covering most of AT&T’s 3G/4G LTE networks in the U.S. One of the striking features of this 4G LTE signal booster by Fustar is the presence of an LCD screen which shows real-time information on the signal quality around you as well as the status of the booster. There are no buttons available, but thanks to features like automatic gain control, this shouldn’t trouble users.

This device comes with an outdoor directional antenna that can be placed on your roof, though we recommend you to provide ample support to make sure it doesn’t move around when there’s a change in weather. Moreover, the antenna will need to be facing the cell tower nearest to your home to get the best range. Though this booster supports 3G/4G LTE networks, it misses out on the older 2G network.

As for the indoor setup, there’s a simple whip antenna that can help offer a range of up to 2,000 sq ft (square feet) at your home. The manufacturer mentions that this should be good enough for 2-4 rooms in a home/office. The signal booster comes with a maximum gain of 65±3dB. In addition to the booster and the antennas, this product also comes with a 50-foot 4D-FB coaxial cable to connect the two antennas.

7. Anycall Network Booster

This is a robust signal booster by Anycell that comes with some exciting features underneath. To start off, it comes with support for bands 12/13/17/5/4/2, which means customers will experience excellent 3G/4G LTE speeds by simply installing this booster in your home. In addition to offering the best data speeds, customers will also see a reduction in the number of dropped or missed calls as well.

As is the case with most cell phone signal boosters, this unit comes with an indoor antenna as well as an outdoor antenna. While several boosters we’ve discussed today offer a whip indoor antenna, this device comes with a more powerful panel antenna instead. The manufacturer provides 50 feet and 20 feet cables for the outdoor and indoor antennas respectively.

Thanks to the powerful 72dB repeater packed inside, customers can get a range of up to 4,500 sq ft which makes this suitable for large warehouses or apartments. This signal booster by Anycell also supports multiple users connecting on the same network. It also supports a handful of other carriers, which can offer an unexpected boost to non-AT&T subscribers.

8. ORPEY Cell Phone Signal Booster

This is a compact yet highly effective signal booster for AT&T cellular networks. As with other boosters, this package comprises of an outdoor antenna, an indoor antenna, and the primary booster box. The company mentions that this is suitable for AT&T’s 700 MHz networks with support for Band 13 and 12/17 included, allowing you to immediately boost your 3G/4G LTE speeds at home.

This booster is capable of offering a maximum signal gain of 65dB, which is on par with most offerings in the market today, though not the best on this list. Though there’s no fancy LCD screen on the booster, it does come with two LED indicators to help you determine between normal status (green) and self-oscillation (red). The lack of a display also means that the manufacturer has built-in automatic gain control for this booster.

Installation is fairly easy on this offering while the company has been kind enough to offer a tool kit to mount the antennas. The product also comes with 50-foot and 20-foot cables for connectivity, thus saving you the trouble of purchasing them separately. When installed, users should experience coverage by up to 5,500 sq ft as per the product page.

9. AT&T Microcell

While network operators are doing everything they can to improve signal quality for its customers, they are well aware that it’s not possible in every corner of the U.S. With this in mind, AT&T released its own signal booster known as the Microcell. This product is manufactured by Cisco which is known for its expertise in the networking and cellular equipment business.

As per the product description of the Microcell, it can significantly boost cell signal quality on your connected cellular devices while also greatly improving 3G/4G LTE data speeds. Customers will immediately see a boost in their signals using the Microcell, though this depends greatly on the AT&T network in your area. We like the fact that this signal can show the network status or the number of bars in real-time, helping you accurately position the antenna.

This is perhaps one of the most compact 3G/4G LTE signal boosters you will come across as there’s practically no outside antenna required. The company mentions that this product can boost your range by up to 5,000 sq ft. Although the features here are not as extensive as on other signal boosters we’ve discussed so far, this is certainly a decent choice given that it is essentially a plug-and-play cell phone signal booster.

AT&T Car/Truck Signal Boosters


1. weBoost Drive Sleek

If you’re looking for the best cell signal booster for your car or truck, the weBoost Drive Sleek has to be on top of your list. It is shaped in the form of wireless charging cradles, which means it barely takes any space on your dashboard. What makes it stand out is the presence of a USB A fast charger that can juice up your phone as you drive. Though most cars come with some form of chargers, this is a good feature to have on a car signal booster.

In addition to boosting your 3G/4G LTE signals, this booster can also enhance 5G signals as per the manufacturer, making this one of the few car/truck signal boosters to offer the feature. The company mentions that installation can be done on your own as all the required tools as well as the instructions are provided with the product.

WeBoost mentions that this car booster can offer a max gain of 23 dB, which pales in comparison to home signal boosters, but is as good as it can get for cars or SUVs. This product is FCC-certified and comes with a 2-year manufacturer’s warranty.

2. HiBoost Cell Phone Signal Booster

This is a comprehensive cell phone signal booster for your automobile, though it’s slightly bigger than the offering we discussed above. However, the manufacturer has ensured that there are no compromises with regard to the performance, thus justifying its size. Firstly, it supports a wide range of carriers including AT&T, Verizon, Sprint, and so on. Though it doesn’t come with support for newer 5G networks, this product does support 4G LTE, 3G as well as older 2G networks.

HiBoost provides all the necessary installation tools and components with the product, though we recommend users to go through the user manual to make sure the setup process is done correctly. The setup also consists of a donor antenna that goes on top of the car/truck. On the inside, a small antenna will need to be placed at a convenient location (preferably the car dashboard).

Similar to home signal boosters by the manufacturer, this product also supports app monitoring using the official HiBoost app. This booster comes with 3-years of manufacturer’s warranty and has been certified to boost signals by the FCC. Though network connectivity can differ greatly when moving from one place to another, this cell phone booster does a good job of providing improved signals inside your car.

3. SureCall Vehicle Signal Booster

This is yet another car cell phone signal booster that has all the bases covered. The company mentions that this can be used with standard cars, SUVs, or trucks. In terms of internal features, this booster is powered by Extended Range Technology to make sure you get the best coverage each time. However, as we’re well aware at this point, cell coverage largely depends on the towers near you.

One of the best features of this vehicle signal booster is the fact that it is extremely easy to install. The manufacturer mentions that it uses a 3-step process to be installed and is easily transferrable to another vehicle. As long as you follow all the steps accurately, it shouldn’t take more than a couple of hours to have this up and running in your car.

Customers have the choice between using a standard vent clip or a permanent adhesive on your dashboard for the internal antenna. This signal booster will significantly enhance your call quality while also providing a decent boost to your 4G LTE data speeds. SureCall is also known for a handful of home cell phone signal boosters.

4. Phonetone Cell Signal Booster

This is a 700 MHz dual band booster for your automobile that can greatly improve existing 4G LTE speeds while also reducing the likelihood of call drops or missed calls. It supports AT&T’s bands 12/17, which means this booster probably won’t work with other networks. The company mentions that it can support up to 50 devices at a time.

Thanks to automatic signal adjustments, this signal booster can sense the environment and provide the best signals accordingly. This also means that you don’t have to adjust the outer antenna each time. The amplifier is relatively bigger than cradle boosters we’ve come across, though it can be easily hidden within your car. The device utilizes the car charging port to power up the antennas and the booster.

Though it’s not complex to install, we recommend users to go through the user manual to make sure all the boxes are ticked. The fact that this booster comes with 5 years of manufacturer’s warranty makes this among the best car cell phone signal boosters available today. Users can also reach out to the manufacturer for tech support over email. It’s worth mentioning that this device can also boost some Verizon frequencies.
