Review on 📶 ANNTLENT Cell Phone Signal Booster: 5-Band Amplifier for Car Auto RV Truck, Compatible with All U.S. Carriers - Verizon, AT&T, Sprint - Boosts 4G LTE 3G 2G Signal by Jim Moody

This thing works great. We have phones with 5G, but there was no 5G at home. We often had barely 4g. Most of the time we had to use wifi which is terrible. We also have a metal roof, the worst cell phone roof. Installed it on the roof. Installed an indoor antenna in the attic. Wonder! We now have 5G at home. Speedtest set the download speed at 145 mb, at best it was 30. My suggestion is not to save. This is the most expensive device this company sells, but it works! All networks are shown so you don't have to worry about which one you are on. When friends come, they get great service too.
