The best cellphone signal boosters in 2022

The best cellphone signal boosters make using your phone at home so much easier and enjoyable. Thick walls and other obstacles can reduce the strength of your carrier's signal once you're indoors, but these clever devices can amplify it and instantly improve the situation. 

That means calls will sound clearer and be less likely to drop out. If you're using mobile internet rather than Wi-Fi, you'll also find surfing the web and streaming music and video a lot quicker. And all this means your phone has to work less hard, so you'll probably find your battery lasts longer too.

Most of these devices come in three parts: an outdoor antenna, the booster itself, and an indoor antenna. You'll probably have to mount the first part to the side or roof of your house, which involves a spot of DIY, although there are exceptions, as we'll detail further down in this article.

Beyond that, you'll need to decide which of two main types of cellphone signal booster you're looking for. The first is directional, which means you point it at a specific mast. This type is best for when the mobile signal outside your house is generally weak. The second is omnidirectional, which means it will draw signals from a full 360 degrees around it. That makes it much easier to set up, but this type will only work if the signal outside is generally good.

Below, we've brought together the very best cellphone signal boosters available in the North America today, all of which supports at least most of the major carriers in the USA and Canada. If you're in the UK or Australia, however, the use of signal boosters is banned.

1. SureCall Flare 3.0

The best cellphone signal booster for most people

Coverage: 3,500 sq ft

Installation can be fiddly

The SureCall Flare 3.0 is the best cellphone signal booster for most people's needs. If you have an average sized home, it should allow you to boost your signal across multiple rooms, at quite a reasonable price. 

How far its coverage will stretch depends on the strength of the existing signal. SureCall estimates that if you have between one and two bars outside, you'll get around 15,000 square feet of coverage inside. With three to four bars, you'll get 2,500 square feet of coverage; with five bars, 3,500 square feet. For the relatively affordable price, that represents excellent value. 

Like most of the devices on this list, the SureCall Flare 3.0 supports all major carriers, including AT&T, T-Mobile, Verizon, Sprint, Straight Talk and US Cellular. And you will need to do some drilling to install the exterior aerial. If you truly hate DIY, though, you may prefer the next model on our list.

Not the cheapest

If you don't want to mess about with drills, then you'll be pleased to know the WeBoost Home MultiRoom saves you the bother. That's because the outside antenna features an adjustable clamp that attaches to a roof-top vent pipe or standard antenna pole. (Alternatively, you can attach the antenna to the side of your home with the included mounting bracket.)

This device works with all major carriers, including Verizon, AT&T, Sprint, T-Mobile, Straight Talk, and US Cellular, and also promises a wider amount of coverage than most on this list, at 5,000 square feet. On the flipside, it is a little bit more expensive than most, too.

Avoid if signal is generally weak

Most of the cellphone signal boosters on this list are directional, which means you need to identify a local mast and point it directly at it. This involves a bit of work, but is the best solution if the signal outside is generally weak. 

If, however, the cellular signal in your area is generally good, you can save yourself the bother by using an omnidirectional device instead. This type of cellphone booster gathers signals across 360 degrees, and so does not have to be pointed in a certain direction to work. It's therefore much easier to set up

For our money, the best omnidirectional cellphone signal booster is the SureCall Fusion4Home. Its makers estimate you'll get 1,000 square feet of coverage if you have one to two bars outside, 2,000 square feet with three to four bars, and 3,000 square feet from five bars. This device is compatible with all major carriers including AT&T, T-Mobile, Verizon, Sprint, Straight Talk and US Cellular.

The best cellphone signal booster for coverage

Specifications

Type: Directional

Fiddly to setup

If you have a very large space to cover, the cellphone signal boosters we've listed so far probably won't be powerful enough. Enter the Cel-fi GO X, which is truly the Rolls Royce option for boosting your mobile signal, both in terms of price and capabilities. 

It offers a maximum gain of 100db, by far the most power on this list. And by utilizing four indoor antennas, it's possible to cover up to 15,000 square feet. That should be easily enough to cover a capacious home or office, as well as retail units, hospitals, warehouses and other business premises.

It supports most, if not all, of the major US networks, although if you're a Verizon user be aware that it's not compatible with 2G or 3G but 4G only. Also note that it tunes itself to one carrier only, so it's not suitable for swapping between multiple carriers.

5. SureCall EZ-4G

The best cellphone signal booster for small apartments

Specifications

Coverage: 2,000 sq ft
Maximum gain: 72db
Networks supported: All major carriers
Type: Omnidirectional
Warranty: 3 years
Money back guarantee: 60 days

Reasons to buy

+
Easy setup

Perfect for small apartments

Not the most powerful

The SureCall EZ-4G is easier to set up than most on our list. That's because it doesn't require an external antenna installation, instead mounting to one of your windows. So you can set it up a matter of minutes, without the need to drill holes or go outside onto a roof. It's omnidirectional, too, so you don't even need to worry about where it's pointing. That does mean, though, it's unsuitable if the signal outside is generally weak.

Otherwise, SureCall EZ-4G a great choice for anyone in a small apartment. And even if you can't get it to work for any reason, there's a generous 60-day money back guarantee that's got you covered.

No good for multiple rooms

Staying in a single room? Then the WeBoost Home Studio is a good choice. It comes in two pieces: a large, directional antenna that goes outdoors, and a small black box that goes inside. You'll need to attach the former to either a pole or the side or roof of your house; the latter you can basically put anywhere. It supports all major networks, is capable of serving multiple users, and promises 2,000 square feet of footage, enough for even the biggest of rooms.

Need a consistent mobile signal while driving? Then check out the SureCall Fusion2Go Max, which we think is the best cellphone signal booster for cars, trucks, vans and SUVs available today. It's got plenty of power, offering up to 50db of gain; not as much as indoor cellphone signal boosters, but more than most in-car ones. Plus the company's Extended Range Technology (ERT) does a great job at boosting available signal consistently and reliably. It's also pretty easy to install.

Not the most powerful

Need a cellphone signal booster for your vehicle, but don't want to spend too much money? WeBoost's Drive Sleek is a lot more affordable than the SureCall Fusion2Go Max (number 7 on our list) but still does a good job. The main limitation is that it will work with one device only. But as long as that's not a deal-breaker, you can save a lot of cash this way. We also love the phone cradle it comes with, which comes with a USB-A port should you need to charge your phone at the same time.
