If you are looking for a top-of-the-line and affordable cell phone signal booster to boost your voice and data signal on any carrier*, including AT&T’s 4G LTE, the Wilson Electronics Sleek 4G-A is the solution. Designed to be used by a single user in a car, the Wilson Sleek 4G-A helps users reduce dropped calls and increases 4G data rates in weak signal areas by amplifying your cell phone's power up to 20 times more than the phone alone. The Sleek 4G-A all-in-one cradle features a signal booster, built-in antenna, built-in mini USB charger port, and is ideal for hands free operation when used with a headset or Bluetooth device. The Sleek 4G-A features simple installation that can be completed in a matter of minutes, and can be easily moved from vehicle to vehicle. Also, the Sleek 4G-A is a great solution for data devices such as a MiFi or AT&T data card.

It's All About Power
The primary cause of dropped calls is low signal output power from the cell phone to the cell tower, which limits the phone’s ability to communicate with the tower. A typical cell phone provides merely 200 milliwatts of output power. To address this problem, the Sleek 4G-A and the included magnet-mount antenna work together to increase the cell phone’s output power by up to 20 times over using just the phone alone.
Enjoy Premium Reception and Fewer Dropped Calls
Using Wilson Electronics’ patented technology, the Sleek 4G-A amplifies signals both to and from the cell tower, increasing the power to penetrate through natural or man-made obstructions, thus enabling you to communicate where you were unable to before. Providing you with a boosted signal, it improves your phone's reception and allows for greater coverage, even when traveling in remote areas with a weak signal.
Compatible with All* Cell Phone Models and Providers
The Wilson Sleek 4G-A is compatible with all U.S. cellular providers for 2G and 3G services including CDMA, TDMA, GSM, and AMPS cell phone technologies, as well as data protocols such as GPRS, 1xRTT, HSDPA. The kit is also designed to boost AT&T’s 4G LTE.

Bottom line, the product works (even inside a concrete city building with no windows). The cons are the device feels bulky. As you are required to keep your phone attached to the booster, I can't quite imagine using it to talk or text for lengthy periods and the cables leave you feeling "tethered". Did a fair amount of research and this product seems like the only/most reliable booster for iPhone 5s on the market right now.
The need for mobile internet for the family while in motion has become a requirement on the last couple of trips. The wife has needed to log in into her work while we are traveling and the one child has online learning class that can be completed while traveling and once its done they can enjoy the trip home without having to worry about rushing to get it done when we get home, plus I never would of thought I would ever here the words from the back seat "Dad the internet is slow" Oh how the world has changed from when I was a kid looking for slug bugs or perdiddle's and asking are we there yet.
Well I decided to give this product a try and I was impressed with it. It did an excellent job at holding 5 out of 5 bars further away from the cell sites with improved data speeds. It also gained an extra 5 miles of coverage going through the mountains before running out of service and yes if there is a no service area it's still a no service area with this product, but it does make those no services area's a lot smaller. Overall when I compared this kit to the same mobile hotspot using the same roof mounted antenna, but without the kit along the same 6 hour trip every year, the Wilson Sleek for AT&T worked better then the antenna alone.Read more ›
Without it, my iPhone 5 gets at most 1 bar of 4G inside the trailer. And even that is lost every few minutes, requiring me to turn my airplane mode on and then back off again in hopes of regaining the 4G.
When using this device in combination with the Wilson Electronics Dual Band - 800-1900 MHz Magnet Mount Antenna with SMA Male Connector and 10-Foot RG174 Coax Cable and the Wilson Electronics Home/Office Accessory Kit for Wilson Sleek, C-Boost , I get a full five bars of consistent 4G. Of course, I do have to put the antenna on the outside of the travel trailer.
What a difference! Very happy with the results!
I installed exactly as per the manufacturer's instructions and headed towards one of our bad areas full of hope. There was no change in signal strength, not even 1 bar's worth. I have tested this in many areas and in each case it was a bust.
My recommendation: Don't waste your money.
UPDATE: Because of the manufacturer's response by email to my bad review I contacted customer service and spoke to Bob. He spent some quality time with me and with his help I got the problem sorted out and the unit is working as advertised. So this turns into a positive review of the product from a grateful customer.
