Top 10 Best Cell Phone Signal Boosters of 2020 – Reviews

Even though we are well into the 21st century, different areas have different cell phone connections. While cell phone service areas have expanded even farther over the past few years, it’s an unfortunate fact that cell phone service is still quite uneven. Weak service can result in dropped calls, no-bars or fuzzy connections. All of which makes a cell phone signal booster a very necessary accessory for a cell phone user to have in many parts of the U.S and the world. However, not all of these signal boosters are equal, so consumers should always try to buy the best cell phone signal booster that they can buy. One that will ensure that they get the best signal possible. With that goal in mind, I’ve included ten models that I feel are the best cell phone signal booster models that can be found currently.

Cell Phone Signal Booster Guide

When you are out of range and need to make an urgent call, a quality cell phone signal booster can help get you out of a tricky situation. Although your call may or may not be life or death, the frustration of not being able to use a service you pay for is now avoidable.

This is only if you use a proven product that ticks certain boxes. A cell phone signal booster must have certain output capabilities among other things and if you know what to look for, making this important purchase can be easy.

What To Look For In A Cell Phone Signal Booster

Downlink Gain

A cell phone signal booster retrieves the signal from a cell tower and this is what amplifies the signal coming from it. To perform to a high level, this needs to be set to a reasonable amount.

Uplink Gain

This is how good the signal your phone is re-transmitted to a cell tower and is all part of what will give you a stronger signal.

Multiple Carriers

The ability to use more than one phone at a time might be crucial to some households as no one wants to wait for mum or dad to get off the phone to use theirs. Although there are still some high performing products that don’t offer this, it should be something you get from the better cell phone signal boosters.

Coverage Area

Because you don’t want to be restricted to within meters of the device, a cell phone signal booster needs to give you coverage throughout your home. The bigger the better here but expect at least 10,000 sq ft of range. This should be fine for most homes and anything else is a bonus.


A cell phone signal booster is only good if it works with your cell phone service provider. A lot of products are capable of boosting signals for multiple companies whilst others are more restrictive in what they can offer.


Because they can be an expensive product to buy, you want to make sure your purchase is protected by a warranty. If it fails to work at any point or the signal becomes unreliable, you need to know you have an ample amount of time to replace it.

Most companies offer a warranty of at least a year whilst some can give you up to 5.

LCD Screen

The easier it is to use, the better enjoyment you will get from these devices. Some come with built-in LCD screens that give you information on signal strength and other useful advice.

Consider The Type of Property

When buying a cell phone signal booster, some are better than others depending on the type of building you live in.

Some products are specifically designed for apartment living and can cover smaller areas. This also means they do not cost as much so there is no point in spending more than you have to.

Anyone living in a larger property or who requires a signal booster for office space will need something with a wider range. Also, for larger companies, there are specialist cell phone signal boosters that might set you back a bit more financially but can cover some serious ground of over 10,000 sq ft.

Cell Phone Signal Booster For Cars

These products are becoming more popular as the in vehicle desire for greater signal increases. They often cost a lot less and are easy to use which makes them appealing and often means you can install it keep your phone close to the antenna for reliable signal.

Signal Strength and Signal Quality

Both of these are important when looking for a cell phone signal booster and are measured in dBm for signal strength and dB for quality.

Because you might be some distance from the nearest cell phone tower, both of these may be significantly reduced which is why you need a product that offers you a good boost of both strength and quality.

Outdoor Antenna Vs Indoor Antenna


Depending on the strength of the signal you can get on your roof, an omnidirectional antenna might be preferential. However, if you are concerned that the strength is weak then you might opt for a directional antenna. These are a bit trickier to install but are better at giving you an accurate signal.

Indoor Antenna

If the outdoor signal is fine, an indoor antenna can be better. Easier to install you may require one antenna per floor for best results. A dome antenna must be attached to the ceiling which can be intrusive and take up room in places you would prefer they didn’t. This is why a panel antenna that can be installed on the wall is popular.
