Kindly Reminds: Before Purchase,

How do i know the right signal booster

Tips :

The Cell Phone Present Operating Network Frequency should be the SAME as the cell booster's (700mhz Band 12 / Band 17)

The Outdoor Original Signal is able to receive 2-3 Bars, so that cell booster can connect with the signals properly between the Cell Tower and Cell Phone. If not, the booster can't operate the signal as expected.


Q1: Why my signal booster can't improve signal inside the house ?

A: Please check if your cell phone receiving signal is the same as the signal booster's ( 700mhz Band 12/ Band 17) ?

- a) Yes , but not work , please check if both of the booster and power supply powered on normally and if the antennas installation correctly as suggested ?

- b) No , I found the cell phone network frequency is different from the signal booster's.then contact seller for Return / Replacement.

Q2: Although both of the cell network frequency and installation are correct, the signal booster not improve signal, Why ?

A : When this happens, turn off the DC power adapter firstly , and then try to adjust of the Antennas isolated distance / Outdoor antenna's height/ Change the antenna to a better place. If the trouble still can't solved ,please send message to us. We accepted 30 Days Return without reasons,3 Months Replacement for defective product.

Q3: What does it mean when the booster indicator red light is on ?

A1: It is not defective. If the booster keep blinking green / steady red light and signal not improved , it mostly becauses of the Outdoor antenna is too close to the indoor antenna signal interference. or, There is space signal interference happened , so the Booster AGC stay on Over power or self-oscillation, so , the signal not improved temporarily .

A2: Solution: Turn off the DC power adapter, Move the outdoor antenna further away from indoor antenna. Make sure the two antennas separated by walls and the isolated distance 25-32ft as suggested. Restart the power supply. If not help, contact seller for other solutions.

Q4: How to register the booster with Serial Number ?

A: Not all of consumers are required to register the booster. It depends on the requirement at your location.

The Guides to signal booster Registration:

Step 1: Open the following registeration link given ,

Step 2: Find out cell carriers(AT&T) that compatible with your booster. Click and Enter

Step 3: Fill in your Location informations as required. and fill in Booster's Serial Number .Very easy to register.

Super easy installation, ran the cable through the walls for a professional install. Plugged in after hooking up cables and immediately had 4 bars! We had zero signal indoors before and only one outdoors, was able to kill the landline and pocket that cost. Unit will pay for itself in 4 months. Very pleased with this booster!

I was skeptical but hopeful. I have a place in the woods with poor signal. I can see the difference when I unplug the unit. I gained 2 bars.

After some trial and error with multiple antennas, this works perfectly. I tried multiple cheap indoor and outdoor antennas. After finally figuring out I needed a yagi outdoor antenna and a ceiling mount indoor antenna, I went from NO SERVICE to 3 bar LTE in the basement of our school. I just set the yagi antenna out the window (not attached to anything) and it was instant success.

I have very weak and even no signal where I live . our signal always on pending Inside my metal barn. I gave this product a try because of its reasonable price, in hopes it would work. I installed this booster .Once everything is mounted, it was plug and play. now we able to get better cell signal inside 3-4 bars while outside (1-2 bars only ). I'm surprised how well this works ! I'm successfully receiving and maintaining phone calls on my cellular inside the house. This cell booster worked for me.

This is working great for us so far. We went from having almost no service in our house most of the time to now having 3 or 4 bars on our phones constantly throughout our 2 story house. Wish I would have done this a long time ago.

"Happy with the result.We installed the booster
Both of my cell phone and my wife's cell phone instantly jumped form 1-2 bar or 4 bars ,we can browse and stream video faster than before.The reason for 4 stars rather than 5 is the antenna is very sensitive to location. so we have to move the. antenna location if it would dropped."

I took a chance use this booster in my wooden cabin , we live in a forest full of trees. our cell service is always weakly. we are able to get smooth text message through the booster. Inside the cabin, we now can get 4-5 bars. Voice calls work well as long as you are inside the cabin.

It's been weak and struggling cell service for years. we should have gotten this earlier. Now It really Solved my cell reception problem.
