Car cell phone signal boosters are proven to work with all USA & Canadian Carriers simultaneously (except "exceptional" kit that works for any single carrier at a time). SignalBooster.com offers the best car cell phone booster options for the money. They can be used in all type automotive vehicles except convertible cars with top down. Car types it can be used in are Hatchback, Sedan, MPV, SUV, Crossover and Coupe.

All kits are 5G compatible. They support 4G and 5G devices including MiFi hotspots, cellular data hubs and routers. The multiple choice drop-down menu provided above gives you the choice to select the best 3G, 4G, LTE, 5G-E wireless coverage boosting system to cover your vehicle in weak signal areas. Coverage can be up to 4 ft. around interior antenna depending upon the strength of signal outside, and the power of the car cellular phone booster system chosen.

Please note: In addition to car cell signal booster, we carry home cell phone booster. Buy both and get better reception everywhere.

Whether for personal or for work use, car cellular boosters, amplifiers, repeaters or range extenders increase reception the same for all type vehicles. The prices shown are only for equipment so please contact us for installation cost if you need us to install it. If within budget, we can schedule time-frame, and designate location for installation. When installed and used as recommended, they improve car cell reception for multiple service provider networks including Verizon, AT&T, T-Mobile, and Sprint.

How do car cell phone signal boosters work?

Cellular signal booster or amplifier kits consist of 3 main parts - Exterior antenna, signal amplifier, and interior antenna:

1. An exterior car roof antenna transmits signals from nearest cell towers into the car via coaxial cable.
2. The mobile signal amplifier amplifies or repeats those signals to multiply them many times over and then transmit them to interior car antenna via coax cable provided.
3. Finally, that inside antenna distributes the strong wireless signals within interior of car to enhance cellphone reception considerably to enable fast 3G, 4G LTE, 5G-E Internet and clear mobile phone conversations.

An important note: Since signal boosters require existing signal outside which they use to amplify and distribute within a car, the size of boosted coverage area near interior antenna will depend to great extent by the strength of signal available for donor (outside) antenna.

Therefore, amount of actual coverage cannot be predicted with certainty. This is the reason why you will see that each booster kit description states, "up to" a specific amount of square footage. No booster can guarantee an exact amount of coverage it can provide. The stated coverage area in square footage, is merely an estimation.

Simple 3-Step Installation Process:

Installation is fairly easy with included step by step instructions. A brief install overview is as follows: 1) Place exterior antenna on roof of car where there will be maximum signal strength. 2) Place interior antenna where signal is needed or lacking for convenient usage within car. 3) Place signal amplifier main unit where you can connect it to both external and internal antennas with provided coaxial cables. Set-up complete.

No synchronization or password needed:

Unlike connecting to wifi Internet hotspot or a Bluetooth connection for wireless earphones, speaker or headset, there's no need to sync cell phone to take advantage of our signal booster system. For Wi-Fi or Bluetooth connectivity, you need to find the correct Wifi network or Bluetooth device and log in to connect by entering the correct password, if required. If you don't know the required password, you can’t connect or synchronize. And if you get a new cellular phone, you have to log in again to that wireless network or synch again with your Bluetooth devices.

However, that is not the case with our cell phone signal boosters. No pairing of devices required. No logging in to connect. No need to do anything. It just works. Our cell phone booster systems are completely transparent. They work with existing signal, boosting from the tower to your mobile phone and back again. This creates an area of strong, reliable coverage in your car. And that boosted signal works for any mobile device within range of interior antenna - automatically. No login credentials, and no password required.

What are the differences between suggested car cell phone booster kits?

We set out to rate performance of many similar car cell phone boosters in the market today because there are too many to decide for a layperson. With an exception of one, they all offer the same max Gain level of 50 dB allowed by FCC on simultneous multi-carrier boosters. They all claim high downlink and/or uplink output power on specific frequencies and bands.

Therefore, we tested them for their real life performance (not price) by going to an area with very weak reception for each of the four major American carriers. The fringe coverage areas of each cell service provider gave us the worst possible situations our customers may actually encounter in trying situations or life and death scenarios. As expected, the results were consistent across all 4 major carriers.

Here's a brief overview of each of the car cellphone signal boosters with their rated performance value (also listed in drop-down menu above for your selection).

Single User.

Suggested N-Range 2.0 is a single user lowest price car cell booster kit for any single SIM-connected mobile device. This is the lowest price range phone booster for car. It has both magnet mount and adhesive mount exterior antenna options for any type of vehicle roof whether metal, fiberglass, or other. It provides coverage improvement on all wireless service provider networks in U.S.A., for any device placed in the cradle. Coverage can vary greatly depending on strength of outside signal. Outside omnidirectional high gain antenna and booster combination provides up to +23 dB Gain. SKU: AFCNRange2. UPC: 697691000411. Cost: US $199.99.

Multi User.

Suggested Fusion2Go 2.0 provides coverage for up to 4 feet from interior antenna. Coverage can vary greatly depending on strength of outside signal. This is the lowest price multi-user phone booster for car. It improves reception of all U.S.A. carrier networks, and all multiple cell devices in car, at the same time. Outside omnidirectional antenna and FCC maximum allowed up to 50 dB Gain makes this an excellent best choice car cell phone booster for city driving.

The single main difference between the Fusion2Go 2.0 and 3.0 is ability of 3.0 version (see "Good Value" sub-title lower below) to communicate with towers farther away such as in remote, distant, far flung locations that are very far away from nearest cell tower. The reason for this is that the Fusion2Go 3.0 has higher output power at up to 29.0 dBm than 2.0 version which offers up to 21.2 dBm which is still equally powerful if not more than almost all other brand model car cell boosters. SKU: SCPolyM250KitAFC. UPC: 697691001036. Cost: US $299.99 (Clearance Sale).
