iPhone Signal Booster Guide & Review: More Bars Instantly

Boosting signal to your iPhone

So you've searched the internet, downloaded apps, contacted Apple, thought about switching carriers, and have looked up and down, but it's still the same result: poor cell phone reception.

Doesn't matter if it's an iPhone 6, 7, 8, or even an Xs -- with no service, you've got a beautiful paperweight.

The question is why.

Is it AT&T's or T-Mobile's fault? Is your iPhone faulty? Do the antenna gods hate you?


See complete iPhone signal booster kits for your situation:

It's actually a variety of reasons that are out of your control.

Cell phone signals are radio waves, the AM-FM kind. And like all radio waves, they are easily disrupted. Almost everything under the sun can alter, absorb, and block your 3G & 4G LTE signal.

Here's why you have poor signal on your iPhone:

  1. Cell tower/site distance
  2. Outside interference: Trees, hills, mountains, valleys, and any tall structures natural or manmade.
  3. Building material: Metal, glass, rebar, concrete, brick, energy-efficient material, and other conductive material (electrical or magnetic).
  4. Internal building obstructions: Thick walls, plaster, drywall, wood and electrical devices & clutter, etc.
  5. Even weather like rain, snow, and thunderstorms.

All it takes is just one or any combination of these factors, and you'll be begging for one bar of 3G or 4G LTE.

But there is a way to improve your iPhone signal.

The Solution:

Everything changes with a cell phone booster.

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

It essentially bypasses all building material, amplifies it inside the home, and allows for boosted signal to AND from the cell tower.

The results? Improved carrier service. Faster internet. Better talk & text.

Here are all the features and benefits of using a cell phone booster:

  1. Works for all cell phones & cellular devices (should you switch to Android, you're still get a boost).
  2. Carrier-proof: Works for all carriers in USA & Canada.
  3. One-time purchase, no monthly fees.
  4. No need for wifi or any broadband connection.

Does It Really Work?


Hey, why the asterisk?

You'll need existing cell phone signal outside your home.

A cell phone booster ENHANCES existing signal, it does not create it.

So here's a simple test. Are you running outside the home to make a call? Do you find your signal to be stronger outside your home than inside?

If so, then yes, a cell phone booster will work for you. 

If you want to get very accurate, you can determine the precise measurement of your cell phone's signal strength and/or cell tower location.

Below are the top signal booster models for increasing your iPhone's signal and service at home, your office, or your vehicle.

Best iPhone Signal Booster For Home

Our Pick 

weboost connect 4g signal booster

weBoost Connect 4G (470103)

  • Boosts Voice, Text Messages, Internet 3G & 4G LTE Data
  • For Whole Home Coverage
  • Up to +65 dB Gain
  • Works with all Carriers, Networks, and iPhone Models

Our Review:

The weBoost Connect 4G has been the bestselling home signal booster for 5 years and counting. 

Although possible for users to enjoy up to 5,000 square feet of signal boost coverage under the best conditions, our customer feedback shows an average of around 2,500 to 3,000 square feet, which covers the average-size of most American homes.

Rural areas should experience a little bit less coverage because of the lack of quality signal.

For most homes, small offices, and small buildings, this is the model you want to get, and why we generally recommend the weBoost Connect 4G to most customers.

weBoost Connect 4G-X (471104)

  • Boosts Voice, Text Messages, Internet 3G & 4G LTE Data
  • For Large Building Coverage
  • Up to +70 dB Gain
  • Works with all Carriers, Networks, and iPhone Models

Our Review:

The weBoost Connect 4G-X is the most powerful home booster from Wilson Electronics.

Usage depends on whether you're in the city or in the countryside.

For people in the city, it's mostly about getting wider consistent coverage with maximum coverage at 7,500 sq ft. People with below to average signals can expect 4,000 to 5,500  square feet of coverage. 

For people in the countryside, if you live in an extremely fringe area with great distance from the cell tower, this may be the model you need to get any signal. 

Ratings: 4.5★ out of 5 (1216 Reviews).


weboost home 4g signal booster

weBoost Home 4G (470101)

  • Boosts Voice, Text Messages, 3G & 4G LTE Data
  • For 1 Room Coverage
  • Up to +60 dB Gain
  • Works with all Carriers, Networks, and iPhone Models

Our Review: 

If cost is a big factor, then the weBoost Home 4G is a decent starter kit.

Under best conditions, you may get up to one-two room coverage. More likely, you'll probably get desktop coverage, about a few feet from the inside antenna. 

So for small spaces like apartments and cabins, it'll get the job done.

If you live in a remote area, we recommend one step up to the weBoost Connect 4G model as a starter kit instead.

Got a Really Big Home or Office?

wilson pro 70 plus signal booster

WilsonPro 70 Plus (463127)

  • Boosts Voice, Text Messages, 3G & 4G LTE Data
  • For Commercial Building
  • Up to +70 dB Gain
  • Works with all Carriers, Networks, and iPhone Models

Our review: 

Ok, so this isn't a consumer unit; however, for very large homes or people in the absolute worst of worst of fringe areas, the  WilsonPro line of commercial boosters should do the trick. They range from range from 25,000 to 100,000 square feet. The WilsonPro 70 Plus hits right in the middle, providing coverage up to 35,000 square feet; for the most part, it averages around 10,000 to 25,000 square feet depending on the configuration and outside signal.

Our professional installers and their big home customers report greatly improved service after installing this booster.

Best iPhone Signal Booster For Vehicle

Our Pick 

weboost drive sleek 4g signal booster

weBoost Drive Sleek (470135)

  • Boosts Voice, Text Messages, 3G & 4G LTE Data
  • For a single smartphone
  • Up to +23 dB Gain
  • Works with all Carriers, Networks, and iPhone Models

Our Review:

This is a car phone mount that boosts signal to the phone, and it's the cheapest of all the recommended car boosters here.

✓ iPhone car mount.

✓ Boosts 3G & 4G LTE signal.

✓ Lowest cost.

The weBoost Drive Sleek boosts performance for a single iPhone when mounted on the cradle.

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

Newer design allows for all models of iPhone.

Ratings: 4.4★ out of 5 (48 reviews).


weboost drive 4g-m signal booster

weBoost Drive 4G-M (470121)

  • Boosts Voice, Text, 3G & 4G LTE Data
  • For multiple cell devices
  • Up to +50 dB Gain
  • Works with all Carriers, Networks, and iPhone Models

Our Review:

So what if you already have your own car phone mount or prefer not to use one?

Then the weBoost Drive 4G-M is something even better. It's been the most popular & recommended car signal booster in North America for about 5 years running.

A slim outside antenna picks up signal. An indiscreet inside antenna (usually Velcroed to the driver seat) broadcasts signal inside. 

It boosts signal up to 4 cellular devices! Great for city and light off-the-grid use.

Ratings: 4★ out of 5 (184 reviews).

For Super Rural Areas

weboost drive 4g-x signal booster

weBoost Drive 4G-X (470510)

  • Boosts Voice, Text Message, 3G & 4G LTE Data
  • For multiple cell devices
  • Up to +50 dB Gain
  • Pro Model: Up to 60% more reach from and to cell tower
  • Works with all Carriers, Networks, and iPhone Models

Our Review:

So let's say you're really deep in the boonies and almost off-the-grid. 

The weBoost Drive 4G-X has 2x the uplink power compared to the Drive 4G-M. 

So that means about 30-60% more reach to the cell tower than your typical car booster.

For drivers in extremely rural or poor signal areas, the Drive 4G-X is the top option to look at. Boosts signal up to 4 devices.
