How Can I Improve My AT&T Signal?

The AT&T network is one of the strongest cellular providers in the United States, but that doesn’t mean it isn’t vulnerable to outages or common obstacles.

Proximity to cell phone towers and nearby natural and manmade obstructions can all impact your ability to make calls and send texts. These include, but are not limited to, the following:

  • Outside interference: Mountains, hills, tall trees, and buildings
  • Inside interference: Metal, glass, concrete and bricks .

On occasion, these factors can even drop your coverage all the way down to zero bars. It’s not always the provider’s fault - even the signals can only go so far.

Luckily, there exists third-party equipment that empower consumers with getting even more out of their cell phone service.

How To Improve Your AT&T Signal

Signal boosters do exactly what their name implies. They can add anywhere from one to two bars to your coverage.

Available for homes, offices, and vehicles, signal boosters work by amplifying pre-existing signals within a given radius to help prevent dropped calls, unsent texts and emails.

After 100,000 solutions provided nationwide, we've compiled a list of recommended signal boosters for improving your AT&T service.

AT&T Signal Booster for Home

Our Pick: Cel-Fi PRO for AT&T

  • Boosts 3G & 4G LTE indoors (AT&T-only)
  • Up to 13,000 sq ft coverage
  • Up to +100 dB Gain

Without a doubt, this is currently the most powerful home signal booster for AT&T. That's because Cel-Fi is the only manufacturer to do carrier-specific models which allows for +100 dB gain compared to the +60 to +70 dB gain from their competitors.

A no-muss, no-fuss model with no cables or wires to hook up. Comes in two wireless units, one near the window to pull in signal and another in the opposite side of the house to broadcast the boosted signal.

Please note that this device only works with the AT&T network, meaning changing carriers renders this device useless for your new service.

Also Good: SureCall Fusion Professional

  • Boosts 3G & 4G LTE indoors for all carriers
  • Up to 8,000 sq ft coverage
  • Up to +72 dB Gain

The Fusion Professional is a powerful pro-grade signal booster, capable of boosting signals inside residential spaces up to 8,000 sq ft under perfect conditions. It's designed for large homes or offices with great outside single, or mid-size buildings with ok to weak outside signal. It uses 2XP technology to double the signal power that is being transmitted, making it a great option for those who live in rural or urban areas with weak outside signal. In addition, it features SureIQ technology to allow the booster to adapt to current signal conditions to prevent it from shutting down due to signal overload.

2XP and SureIQ are unique to SureCall, making their products some of the best performers in all situations and highest-rated home boosters. And as an all-carrier booster, the Fusion Professional is compatible with all major US carriers, should you want a future-proof booster.

For Smaller Spaces: weBoost Home Room

  • Boosts 3G & 4G LTE indoors for all carriers
  • Up to 1,500 sq ft coverage
  • Up to +60 dB Gain

For those needing to improve their AT&T signal in 1-2 rooms, apartments, or small houses and offices no larger than 1,500 sq ft, the Home Room is a fantastic choice. It’s not the cheapest, nor the most expensive in the small home category, but it is the most popular.

The Home Room is extremely flexible and easy to set up. It comes with a flat window cable so that you don’t have to drill holes on your walls, which is extremely helpful for those who live in apartments. In addition, the outside antenna comes with different mounting options, one of which is an optional suction mount to install the antenna on a window rather than on the roof.

This reliable, budget-friendly unit works with all carriers and provides coverage up to 1,500 sq ft under perfect conditions. Your outside signal strength determines how much coverage you will receive. Most people get about 200 to 500 sq ft of coverage.

AT&T Signal Booster for Vehicle

Our Pick: Cel-Fi GO+

  • Boosts 3G & 4G LTE for AT&T
  • For any car, truck, RV, and boat
  • Up to +70 dB Gain

With gains of over +70 decibels (compared to the +50 or so for the competition), ), the GO+ is the most powerful car signal booster available for customers on the AT&T network. The GO+ is carrier specific, meaning only one carrier, AT&T for example, can be amplified at a time. At the point of purchase, you will have to choose the carrier you want the booster to work with, but this can be changed later. If you ever wished to permanently or temporarily change the carrier that is being boosted, the Cel-Fi Wave app can help you do just that, as well as remotely monitor the signal from the palm of your hand.

Also Good: SureCall Fusion2Go Max

  • Boosts 3G & 4G LTE for all carriers
  • For any car, truck, and RV
  • Up to +50 dB Gain

The Fusion2Go Max is one of the best all-carrier car signal boosters around. It features Extended Range Technology™ (ERT) to maximize the communication between the devices inside the vehicle and the cell towers. As a result, you and your passengers will receive the best possible cell signal regardless of which carrier each person uses. It will work best in urban, suburban, and some rural areas.

For Cradle Mounts: weBoost Drive Sleek

  • Boosts 3G & 4G LTE for all carriers
  • For any car, truck, and RV
  • Up to +23 dB Gain

This weBoost Drive Sleek comes with a cradle mount to accommodate a wider range of smartphone and tablet sizes, so great for a hands-free experience.

It can be used in rural settings, but consumers tend to get more bars and better coverage in urban areas. With gains of more than +23 decibels gain, the device works in cars, trucks, and RVs.

AT&T Signal Booster for Commercial Buildings

Our Pick: Cel-Fi QUATRA for AT&T

  • Boosts 3G & 4G LTE indoors for AT&T
  • Up to 200,000 sq ft coverage
  • Up to +100 dB Gain

Hands down, AT&T’s most powerful signal booster for commercial buildings. All-carrier boosters will only provide gains of around +70 decibels, whereas this AT&T-specific device will boost to over +100 decibels. That's about 1000x more stronger! This model comes in two parts:

  • A network unit (NU) works with amplifying existing signals and supports up to four coverage units.
  • A coverage unit (CU) broadcasts amplified signals in areas up to 50,000 square feet. So a fully-stacked QUATRA is capable of covering up to 200,000 sq ft.

The Cel-Fi QUATRA is also notable for using power of ethernet (PoE) Cat5e cables instead of the usual coax cables, predicated on the fact that digital signals are of a far higher quality and sustainability than their analog counterparts. So cable runs are 3x compared to RG-6, LMR400, and other analog cables.

Also Good: WilsonPro 1100 (50 Ohm)

  • Boosts 3G & 4G LTE indoors for all carriers
  • Up to 35,000 sq ft coverage
  • Up to +70 dB Gain

This commercial signal booster is one the most powerful pro-grade boosters available. The WilsonPro 1100 is capable of sending and receiving information from far distanced towers to provide you with the best possible AT&T signal. It’s designed for large homes and commercial buildings located in extremely rural or urban areas. With its XDR technology, the booster will automatically adjust itself to current signal conditions to prevent it from being overloaded.

Money Saver: WilsonPro 70 Plus (50 Ohm)

  • Boosts 3G & 4G LTE indoors for all carriers
  • Up to 25,000 sq ft coverage
  • Up to +70 dB Gain

With a range of up to 25,000 sq ft, depending on the configuration and strength of the outdoor signal, this popular all-carrier signal booster has been a bestseller for Wilson Electronics. It’s designed to improve AT&T, Verizon, Sprint, and T-Mobile signals inside commercial buildings and large residential homes in urban, suburban, and rural areas. You and your loved ones, employees, clients, or visitors will no longer have to deal with dropped calls, unsent text messages, and slow data.

Why It’s Not 100% AT&T’s Fault, It’s Also Your Building Material

building materials

Over 80% of cell phone use is made indoors and over 72% of indoor cell phone use suffers from dropped calls, poor voice quality, and slow internet.

The reason why?

While some of it is AT&T’s network coverage, another major factor is your home & building. Specifically, your building material.

While cell tower distance and outside interference (trees, mountains, and tall structures) do affect your cell service, the number one reason why you’re not getting reliable service is because of building material and layout weakening and disrupting cellular signal from reaching your phone.

Let’s look at the top 7 reasons:

  1. Metal: Metal is the #1 disrupter of cellular signal. Aluminum, brass, copper, steel, iron, tin, etc. Any type is capable distorting your cell service.
  2. Low-E- Glass: Energy-efficient and green-rated buildings are great at saving energy but also great at blocking out cell signals.
  3. Brick/Concrete: Brick walls and concrete walls are robust material that weaken or block service as it passes through.
  4. Plaster /Drywall: Although it doesn’t completely shut out service, it does weaken it as it passes through.
  5. Wood: Depending on the thickness of the wood, it’s capable of absorbing cell signal.
  6. Thick Walls: Internally, thick walls absolutely hamper cellular reception, especially as it tries to reach the center of the building.
  7. Electromagnetic Interference: Any machine (TV, computer, wireless device) emits RF noise that potentially disrupts cell service.

So even if you're right next to a cell site, these factors can contribute to poor signal quality. That's why more people and companies are investing in signal boosters.

Finding Your AT&T Cell Phone Signal Strength & Cell Tower Location

There are various ways to read your cell phone signal strength. While the number of bars is a good representation, it's not entirely truthful, because the number of bars that correlates to signal strength is subjective across all carriers.

The most accurate way to read cell phone signal strength is in dBm. Cell phone signal is measured in dBm, -50 dBm is great signal (full bars) and -120 dBm is poor signal.

The following methods are best practices to find your dBm :

Field Test Mode (Using Your Cell Phone)

For iPhone Users:

iPhone users have a more difficult time to find their dBm reading since Apple removed easy access to dBm readings in Field Test Mode, and they also have two iPhone chipset models: Intel & Qualcomm.

If you're an AT&T customer with an Intel chipset for iPhone, it's possible to find your dBm. Here's how:

  • On phone mode, call: *3001#12345#*.
  • If you see the following options: Device Info, LTE, UTMS, and GSM, congrats, you can find your dBm. ios 11 att
  • Tap on LTE.
  • Tap on Serving Cell Mea.
  • The number next to RSRP0 is your dBm reading.

If you can't find your dBm using this method, try our recommended smartphone apps below.

For Android Users

Android is an open system unlike the iPhone, so it's easy to access your dBm reading.

These are general instructions. Some manufacturers may have different options, but these instructions will get you there or mostly there. Here's how:

  • Access your Settings.
  • Tap on About phone.
  • Tap on Status.
  • Tap on SIM status.
  • Your dBm reading is under Signal strength.

Smartphone Apps

Downloading apps are a great way of finding your nearest cell tower and dBm readings. There are countless cell signal apps, luckily, we've curated a few we use regularly.

Below is our recommended apps for testing your cell phone signal speeds:

For iPhone Users:

Because Apple has hidden dBm readings, the next best thing to is to measure your internet speed which the following apps can do:

For Android Users:

These are comprehensive apps not only show your dBm but also noise (RSSNR) and quality (RSRQ).
