Our customers reviews

Charlie Bivens

Worth the money!
The item delivered on its promise. I have spotty cellular coverage and sluggish mobile internet where I live. I stopped receiving missed calls after I installed the booster, and now I can watch films on my phone inside my house without them buffering. Excellent value for the money!

Thurman Fisher

Happy with the Purchase!
Quick delivery, excellent packaging, and brand-new parts. Installation was moderately simple; however, since I mounted the antenna outside, I had to lead cabling to the cell signal receiver. Straightforward. simple to follow directions My cell signal was enhanced by the unit from 1 to 3 to 4 to 5 bars.

Kristi Hughes

Amazing Product!
We were recommended this product by a friend, and we're glad we tried it out. Previously, we would typically have one bar of signal in and around our house on a good day, and none on cloudy days. Since we run a business from home, this was a major inconvenience. Even my husband, who isn't very tech-savvy, managed to set it up without any help. The signal booster started working immediately, and we now enjoy full bar coverage in and around our house. It has made a significant difference for us, and we no longer have to worry about signal issues affecting our work.

Boosters are devices that boost your existing signals for 2G, 3G, and 4G networks. They catch the signal from outside, usually from the nearest cell tower, and then pass these signals to the booster box. The booster amplifies the existing signals and spreads them in the house or office or anywhere you want to improve your signal.
Poor mobile signal can be caused by several factors, including thick building materials that block the signal, obstructions such as nearby buildings or trees, and the cell tower position and distance.
If you want to find the best booster for you there are 2 options. the first one is to go through our advanced filter options to find the best booster based on your needs. If you are not able to find the best fit for you after using the filter, then you can contact our technical support team, and they will be happy to assist you to find the best offer for your needs.
