IMPORTANT SIGNAL INFORMATION: If you're purchasing an amplifier for use at one specific location, we strongly recommend doing a site survey first to determine whether the amplifier will help you and to give you an idea of what kind of results you can expect from it.

If your signal is extremely poor (-108db or worse), an amplifier may not be effective - there must be some usable signal available for the amplifier to boost. Conversely, if the signal is too STRONG at your location (-50db or better), the amplifier may shut down to avoid interference with the tower.

Now there’s a mobile signal booster that works with virtually EVERY network – the Sleek 4G from Wilson Electronics. This powerful signal booster helps you stay connected by providing a strong reliable signal in weak-signal areas, reducing lost connections and speeding data rates. It boosts both voice and data communication – making it perfect for phones and wireless hotspots.

The Sleek 4G works with all devices on most conventional 2G, 3G, and 4G networks in the US and many more around the world. Wilson signal boosters feature cell site protection technologies refined over more than a decade of research and development. Optional indoor accessory kit (sold separately) allows use at home or in the office. FCC type accepted.

How it works: The antenna (sold separately) picks up the cellular signal and sends it through the cable to the cradle amplifier. The signal is then boosted and pushed out to the phone or device sitting in the cradle.

I was very pleased with the improvement in our cell phone signal after we installed the unit. We live on an islland in the Exuma chain of island in the Bahamas and internet service is through a cell phone tower a few miles away. After installing the device we were actually able to do Skype and occassionally Magic Jack phone. We had never been able to do either prior to this time

The Wilson Sleek 4G-A Signal Booster is the greatest gadget that I research in an effort to help signal around the country side around Texas. Thank you Wilson Sleek 4G-Signal Booster. It is great and all the information about how to use it was there and easy to follow.

We have had this booster now for a couple of weeks. It has done what it is suppose to do. We are gate guarding in the oil patch of South Texas and was having some issues receiving a good Verizon signal. Works great. We are able to use our Laptops with the data and also able to make phone calls. But we have to switch from one devise to the other, since it is only good for one or the other.

Improved my signal strength by 14-16 dB both on a Novatel 4620L and a Pantech USM-290. Signal went from 2 bars to 4. The antenna that comes with it worked as well as the 13" antenna that I had here already so I stuck with it. I tried their suction-cup window mount but got a better signal by sticking the magnetic base to a 2-1/2" diameter steel part I had and putting it on top of a 6' high book shelf. You could use a can of mushrooms and get the same result. If using indoors like me, you need at least a 2A USB power supply for proper operation.

I am giving 4 stars as my use has been limited to this point but I am very happy with the unit. The included mounts work well with my Galaxy S4. I have only used the unit on the Verizon network with the factory antenna and I am getting a 20 dBm boost of signal on the 2G, 3G and 4G LTE networks. I am looking forward to trying it with my 9 db trucker antenna after I get the connection adaptors. I RV boondock in fringe area's and have used a hardwired booster on 3G area's for years but unfortunately the new phones cannot be used on that type of amp. The true test will come when we travel next year and I have a chance to use it on the road.

Good price point. Works well. Dead zones in my area have been significantly reduced.

I live in a rural area where I cannot connect via DSL, Cable or Fiber. My best option was a Novatel 4620LE Mifi setup. I need to use the Verizon footprint. Without the Wilson (on a good day) I was getting 4GLTE 2 bars and the RSSI was in the neighborhood of -112dBm (not good). Using the Sleek, I am pretty consistently getting 4 bars with around -90dBm, still not the greatest but my speeds are generally around the 17mbps down and 3mbps up. A far cry from where I was before 4G. Very happy with the product. I know that the review says to focus on the product but I cannot say enough positive things about 3GStore support. They worked with me during the pre-sales and post sales process... they are my first choice for products of this type. They truly want their customers to be satisfied.

We bought this to go along with our 3047 3g4g full-band-outdoor-omni-antenna and low loss cable assembly. We love the results and found even South of Quartzsite in the desert we were getting 4g service on our Verizon Mifi card when others were not getting any service. We're using this setup in our Winnebago Adventurer and would highly recommend it.

Lots of extra brace config to adapt to many indoors surfaces
