Cell Phone Booster for Car, SUV, Van|Vehicle Cell Signal Booster for AT&T, Verizon, T-Mobile & All U.S.Carriers|Boosts 5G/4G LTE/3G on Band12/17/13/5/2/25/4/66|FCC Approved

The device has two antennas, are they can "talk'" to each other if they are too close together. That's what all the green "alarm" lights are about. Device also automatically reduces power to the output signal to save energy. This makes is difficult to know if it is actually working, and working correctly when the "bars" on my phone fluxuate so much. It does work, and after I figured out all the tidbits of operation, I like it. I do recommend this product, but it can be confusing to those who are not used to playing with these kinds of toys. Also, the words "inside" and "outside" are molded into the case over each of antenna connections, and these are VERY VERY hard to see and to find. You MUST connect them correctly or no ticky no worky. This product is very reasonably priced for what it does. : )

We use these for our field technicians. The one in my car I could not get things to load fast on my phone but with it plugged in the Download rate returned. Biggest thing to know on this is it only boosts what signal is there and cannot make it appear from nowhere. We run about 8 of these every day.

Returned item. Before you buy this product, complete at least two tasks. 1. If you have an iPhone dial 3001#12345# and read your local LTE RSRP or 5G RSRP/RSRQ or both. If the RSRP is -120 dBM or worse (a more negative number) the boost will be negligible and is not worth owning. 2. Find a spot along your drive where you nearly drop a call or it gets substantially garbled. If your call improves while using this product, it is a worthwhile buy. I was not the target client because the LTE RSRP was already -117 dBM. I also run the FirstNet Federal connectivity aid through AT&T to get preferential treatment on cellular towers as a first-responder for work emergencies but in a rural, dead corridor in eastern CO there was no change when I dialed 3001#12345# on my phone. Perhaps the Federal FirstNet offers the best possible signal boost and any supplement will have no additional impact. Two days later I drove through metro Denver, where 5G is ubiquitous, to monitor both the LTE RSRP and the 5G RSRP/RSRQ but there was hardly a change. I tried finding dead zones where I could call with it on and off, notice a difference, but nothing. The company is professional, hard working, but the product did not work in my context.

just wouldnt help in my remote area,signal is almost non existant here

West Tx oil field.. I’ve had all of the Weboost and this one smokes them! Only wish all 3 cords were longer. Would order the one for RVs for the truck..

This may work perfect for car use but not for anything bigger. I bought it to use in a camper but after reading the instructions that it will only work from 2-4 feet from the inside antenna, I could not use it. They show it mounted to the side of the divers seat so that its only a couple feet from anyone sitting in a car. So if you buying for a car, I imagine that it would be fine, I can't say. I sent it back.

It works with Veraizon. it increases a single signal line . but it is enough for the most remote places.

I have about a 2 mile section where I drop signal to and from work through some wetlands. This took me approximately 10 minutes to set up. When driving to work today, I was getting 5g the entire way. I am so impressed.
