This cheap cellular signal booster is on clearance sale. It is not refurbished signal booster. This 3G car & truck cell signal booster is comparable to the more popular SureCall branded 3G & 4G LTE in-vehicle cell phone booster.

It boosts mobile service reception with a whopping 50 dB Gain. Theoretically, -100 dBm signal strength means no bars and no service, and -50 dB signal strength means peak service or 5 bars in a smart phone. By improving signal strength from -100 dBm to -50 dBm using this device with up to 50 dBm Gain, you can technically turn a dead zone in your vehicle to peak performance - From zero bars to five bars!  

This travel cellular signal booster/ amplifier/ repeater kit improves in-vehicle wireless reception for multiple cell-phones simultaneously! Everyone can now enjoy the freedom of clear calls and instant texting while inside your car, truck, recreational vehicle, or boat.

It is "service provider agnostic" meaning it is designed to improve the signal quality of all USA cellular service providers such as AT&T, Sprint, Verizon, T-Mobile and all Canadian mobile service providers such as Bell Mobility, Telus, and Rogers Wireless.

Smart HiBoost Signal Booster Functions:

AGC and MGC.

Hi Boost Travel Booster Kit is equipped with smart MGC and AGC functions. AGC automatically controls system gain according to input signal in your area. It balances booster power in order not to interfere with mobile operator's networks. Thanks to the MGC function, it is possible to increase or decrease booster gain manually!

Indication LEDs.

Thanks to indication LEDs on booster interface, it is easy to keep an eye on booster's current working state. Alarm LED will also warn you if there's any oscillation or trouble which can then be corrected.


This in-vehicle signal booster will not improve 4G LTE data speeds because this booster is mainly for vehicles and it is not a critical necessity to use 4G mobile internet. Cell phone calls and texting while not driving is allowed and only those critical tasks (voice calls and text messaging) are greatly enhanced by this cell phone signal booster for car, truck, etc.

Questions & Answers


Ask a Question
  • Does the indoor antenna have to be mounted or can it just lay on the dash or hang on the door to work

    Technically, an interior antenna does not have to be mounted for it to work but it is always safer to fix it in place which is also required by law in many states (not having any loose devices that can cause damage/ injury in event of an accident/ impact/ jerk, etc.

  • Does this amplify 4g?

    No, this amplifies only 2G and 3G network bands but on all frequencies of all cellular service carriers.

    If you have a 4G phone, this will not improve 4G data reception but you can technically force the phone work on 3G network (option is in the settings area) and you will realize the signal boost for your data connection.

    For voice connectivity, most carriers use 2G & 3G network so you will experience better voice clarity and reduced dropped calls thanks to stronger 2G & 3G connection that this booster will help you achieve.

    If you have 4G or LTE smartphone, tablet, and other devices and don't want the hassle of manually changing the network to 3G to take advantage of boosted reception whenever experiencing wireless connectivity problem, we would highly recommend a 4G vehicle signal booster kit which is backward compatible and boosts 3G network speeds too, in addition to 4G LTE.

  • Is this item easy to set up or we have to set it up by a professional installer?

    It is very easy to install on your own by following easy to follow instructions provided with this in-vehicle cell phone signal booster kit.

Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles. Before ordering, please check outside signal level in decibels or ensure that you can make and hold a phone call at any good spot outside where you can mount an exterior antenna. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

Kevin K. of Anderson, California gave the following review:

Website is easy to use with plain straight forward info but could have had more on testing signal strength to make sure you get a strong enough booster.

Therefore, please note that stated sq. ft. coverage is based on good signal outside. For best results: If outside signal is weak, we suggest choosing the next higher sq. ft. coverage kit. If outside signal is very weak, we suggest choosing the kit with even more higher sq. ft. range bracket. Basically, higher the sq. ft. bracket, the more powerful the signal amplifier with greater Gain as well as higher uplink and downlink output power.

If outside signal is too weak (weaker than -110 dB), submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

For non installation-included kits: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
