The Cel-Fi does away with all the complicated setup, issues, and installation costs of typical signal boosters. No mounting antennas to the roof, running cables through walls and ceilings, and no unsightly panel or dome antennas on the walls and ceilings. Instead the Cel-Fi PRO has just two pieces of hardware, a Network Unit (NU) and a Coverage Unit (CU). Installation is as simple as placing the NU in a window where the AT&T signal is the strongest and connecting it to power. The CU is then placed elsewhere in the home or office and connected to power. The NU picks up and amplifies the AT&T signal, wirelessly sends the signal to the CU, and the CU pushes out an amplified cellular signal for any devices in range. It is that simple!

This signal booster was the most effective and least expensive option for our office!

The product was recommended for poor reception in our office. After working with the 3G store team we were able to fine tune and adjust the location and settings which greatly improved our connectivity issues. I would recommend the product and team.

Compared to the ATT Microcell the unit is more reliable however the space covered by the enhanced signals is slightly bigger area compared to Microcell. Overall it's a reasonable unit, a little expensive construing the square footage it covers is not 13000sqft!

I was able to place the order by phone with excellent support to overcome difficulties to place my order online and charge it to a credit card with an address from Puerto Rico.

It does not boost AT&T LTE signal at all, it does not even find it. All it does is 3g and 4g. My iPhone 6s gets 2 bars of LTE at the window where I setup this device. The Cel-Fi Pro only finds a 4g signal (the app shows it as 3g for some reason). I have tried moving it all over my upper floor without any difference. It does boost the 4g signal to 5 bars, but without LTE it is an expensive paperweight. I am sending it back as soon as I can get a RMA. Beware if you are thinking about getting one.
We're sorry it's not working for you! Please give our tech team a call at 866-347-8673 ext 3 so we can troubleshoot with you - there are some things we can help you with to see if we can get it working. If it doesn't work out, we'll be glad to assist you with an RMA.

Before the booster I had 1 failing bar, now I get 3 continuous bars, it has improved the signal in my house consistently.

Device working fine in our office, our IT guy was pleased on how easy it was to setup. Everyone in the office is now enjoying a strong signal. Life is Good
