Goboost Cell Phone Signal Booster for Home and Office, GSM 3G 4G LTE 5G Band 2 and Band 5 Cell Signal Booster Amplifier Repeater for Verizon, AT&T, T-Mobile & More | FCC Approved

I used this in my cargo trailer that I built for camping. I’ve tried other signal boosters but have not had as good of results. The places I camp are off the beaten path. In the past I would get no service or 1 bar with my phone outside the trailer and no service inside. With this booster I receive 3 to 4 bars inside and can stream movies with no buffering. Goboost performed far beyond my expectations. I had no need for tech support but they did reach out to me to make sure the install went smoothly. I mounted the outdoor antenna on the end of a expandable paint pole. I powered it with a 120v inverter on my solar system. A 5volt dc to dc adapter would also work fine. A simple install that took me less than 45 minutes. Make sure your service is on the same bands that this booster works on. I will buy this again for my home. Great product!

I have not had this unit for a week yet, but my phone has a better signal than I have had in my metal sided/metal roofed home in the Kansas flint hills--and this is not my first booster. There is not much signal to work with but this booster seems to be capitalizing on it. Without a cell booster my signal is non existent (-127 to -131 dBm). Initially this brought my signal to -113 dBm, but after moving the outdoor antenna and the inside components and monitoring the changes on Network Cell Info Lite, I have a signal in the -70s. That is an enormous improvement and better than I expected in my situation. By the way, it is showing all bars on the bottom (outside signal) and none on the top for output, but it is working nevertheless.

This booster performs just as advertised. It will not improve a nonexistent signal, only amplify the signal you have. I'm at the edge of cell service, but this device has worked very nicely for me.

Took an hour or so to install, drill holes through walls, and mount and fairly easy to figure out where to orient antenna to pick up the right band signal. Required no software training to find the signal for the phone. phone worked immediately inside the metal shop. time will tell us about longevity and reliability but so far in the first two or three weeks it has worked perfectly.

I live in a spot that is a cell phone grave yard!After installing Goboost I went from1 bar outside to full bars inside!I love this thing. Now I don't have to go outside to make a call!

Inside my metal building had no bars and out side only one bar. After installation 3-4 bars inside. It's a small room so covers it well. Doesn't extend very far but perfect for my situation.

We looked up which channels the cell towers in our area used, and bought this because it was supposed to work on those channels. We got absolutely ZERO benefit or improvement with this installed. It was a total waste of time for us. Thankfully Amazon accepted this return because it was an expensive paperweight for us.

It works well if you have good signal outside and need to bring it in. If not it only boosts your already poor signal and makes it "louder".
