Review on 5 Band Cell Phone Signal Booster for Car, Auto, RV, and Truck - Amplifies 4G LTE, 3G CDMA, 2G GSM Data & Voice Signals on Band 2/4/5/12/13/17 - Supports All Phones & Carriers (Verizon, AT&T, Sprint, Cricket) by Dusty Oner

I bought this for my farm. There are several areas where I have a very weak or very weak signal. It definitely got stronger in areas where I have low signal strength. I was hoping to get a signal that I could at least use for text messaging from other areas if needed. This didn't solve this problem, if my phone doesn't have at least 1 bar it won't boost. However, it "usually" doubles my signal from 1 to 2 and the speed increase is noticeable. It won't be able to deliver 5G speeds from a single LTE band, so meeting expectations is important. However, it picks up a weak signal and amplifies it.
