Review on 📶 HiBoost Cell Phone Signal Booster for Home with Smartphone APP, Coverage up to 10,000 sq ft, All Major US Carriers – AT&T, Verizon, T-Mobile, Sprint & More, FCC Approved by Javarie Brumfield

We'll call customer service tomorrow. Built-in parts were missing. The attitude was not clear. The instructions are very difficult to understand. A friend who was a programmer tried to help us but to no avail. Hope it works! We wouldn't know. Very frustrating so far. Also, any help from the app he was referring to was useless. We used this booster to increase cell coverage, so we worked in an area with 1-2 service bars where - shock! - There wasn't enough service to go on site as he kept offering to help with installation. UPDATE: Works. It only increased the service by 1-2 bars after 11am to get everything working. We monitored the sensors in the app. Here is my biggest problem. 10,000 square meters is there. ft. What he doesn't tell you is only if you buy some (up to 4) extra internal antennas, buy a splitter and connect solid wires to it. Also, you will only receive this service if you are within 20 to 30 feet of an indoor antenna (installed at the end of a 50 foot cable). If I'm not the only one who reads it, it covers an area of 10,000 square meters. It's not without spending the extra $2-300. So unless you're willing to pay close to $900 for a small increase, I don't recommend it. If I were in an area that already has 2-3 bars I wouldn't waste money. All it did was get the power signal into our shed.
