Please pay attention before you place the order:

1. Please confirm your mobile phone frequency first before you purchase it, if you don’t know how to check, you can contact us or call your mobile phone operator. Frequency doesn’t match, the signal booster can’t works.

2. Please make sure your mobile phone can receive at least 1 bars signals outside, otherwise this signal booster can’t works. It needs outdoor good signal to improve your indoor signal.

3. The last but not the least, please install follow our installation steps. If really can’t works, please contact us attached pictures or video, so that we can help you check and solve the problem for you.

What makes it different with other booster?

The features of our signal booster are:Wide Input Voltage;Self-oscillation Elimination;Inactivity Mode;Automatic Gain Control;Automatic Power Shut-down;Manual Gain Control;Automatic Level Control.

We offer a three-month free replacement and five-year warranty.

Wide coverage

It can guarantee the better signal output under the condition that the signal is weaker.A signal booster host can cover the whole family,so as to achieve all-around and no dead end coverage.

The effect of amplifying the signal is obvious

The signal is get better, the communication Internet speed is unimpeded.

Inactivity Mode

When no user calls, the device works in standby mode, the uplink power amplifier is switched off, and the static power is decreased by 30%, so as to achieve the purpose of energy saving.

Installation method of antenna

For installation:1. Make sure there is a separate wall between indoor and outdoor antennas, so that the two antennas signal don't interfere with each other.2. Please make the distance of indoor and outdoor antenna is more than 10 meters and do not put them in the same level.

Working principle of the booster

The outside  antenna access strong signal from cell tower and send it to the booster through the cable. The booster receives the outside signal and amplifies it,  and sends it to the inside antenna. The inside antenna broadcasts the boosted signal to devices inside your home.
