If you're like me and live in an area with spotty cell service, the INVCALL Cell Phone Signal Booster feels like a game-changer. After struggling with dropped calls and slow data in my home office (which happens to be in the farthest corner of my house), I decided to give this booster a shot.
The good news? Once it's set up, it works beautifully. I went from 1 bar of LTE to a solid 3-4 bars throughout my entire 3,000 sq ft home. Video calls that used to buffer constantly now stream smoothly, and I haven't missed a single work call since installation.
The LCD screen and Signal Advisor APP are genuinely helpful features. Being able to see real-time signal strength and frequency bands makes troubleshooting much easier than with other boosters I've tried.
However - and this is a big however - the installation process isn't for the faint of heart. Like one reviewer mentioned, this isn't the most user-friendly system out there. It took me about 3 hours of fiddling with antenna placement (and watching multiple YouTube tutorials) before I got optimal performance.
The included accessories are high quality though. The window cable meant I didn't have to drill holes, and the waterproof tape gave me peace of mind for the outdoor antenna connection.
Bottom line: If you're technically inclined or willing to put in some setup time, this booster delivers excellent performance at a reasonable price. But if you want something truly plug-and-play, you might want to look elsewhere or budget for professional installation.
