Our customers reviews

Jonathan Campbell

Jonathan Campbell
The item delivered on its promise. I have spotty mobile 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!

Alice Lamb

Happy with the Purchase!
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.

Charlie Duncan

No more dropped calls!
Quick delivery, excellent packaging, and brand-new parts. Installation was moderately simple; however, since I mounted the antenna outside, I had to lead the 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.

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 Spark phone 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.
