Working Principle

1. RECEIVES SIGNAL

The powerful antenna reaches out to access a good signal, and delivers it to the booster.

2. BOOSTS SIGNAL

The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.

3. BROADCASTS SIGNAL

Your devices get increased cell reception, and calls and data are fed through the booster back to the network.

Band Story

GOBOOST GSM Repeater LTE 4G DCS Cellular Amplifier 2G 3G 4G Cellular Signal Amplifier GSM 900 1800 2100 Mobile Signal Booster -

Common Problems

Question: no signal on the display and phone

Solution: adjust outdoor antenna, put it at a higher postion and make sure it could receive good signal from base station.Or please check the freqeuncy of your antenna, if you buy only booster from us. If the frequency doesn’t match to the booster’s, it could not work either.

Question: the display is blinking and signal light isn’t on.

Solution: Also adjust outdoor antennna as above, because blinking means receiving signal is not stable. Adjust the position and direction of outdoor antenna until it stop working.

Queation: the signal is at maximum on booster but the signal on the phone does not improve at all

Solution: It is what we called “self-oscillation phenomenon”. You need to increase the distance of indoor antenna and outdoor antenna and separae them with a brick wall. Make sure there is no opening area between them.

Question: The booster works properly but the signal light is not on

Solution: Maybe the cable is too long for the booster or the connection is not well. Please make sure all the antenna are connected well and tightly. It actually does n’t matter too much as long as the device works well.

Any other problems about the product or installation, please contact us.
