Working with the 3 Network the cell phone signal booster GSM 2100 + 3G will also boost your 3G signal as the name itself also implies.

This is a full kit that comes with all the required parts for amplifying your weak signal and releasing you from the stressful interrupted calls. The kit comprises external and internal antennas, a 10-meter coax cable and AC/DC power supply. With all this in mind the model also has a pleasant design that will not make you think of hiding it somewhere from the eye.

What regards the installation then it’s very simple and requires only 15 minutes. You need to put up the external antenna outside and connect it to the repeater with the cable. Then connect the internal antenna and turn on the booster by switching it to the power. The 5-bar signal is guaranteed.

If you are worried about any harmful effects that the booster’s waves might cause then be sure that the waves a signal booster emits have been proven to make no change in the presence of such devices as cell phones and computers.

In case of any problems or questions feel free to contact our team – we are available 24/7 and will guide you through the process making it much easier. This can boost Vodacom, MTN, Cell C.

    Easy ordering and fast shipping. I needed the repeater at our summer home in the mountains. It boosts from 1 bar to 3bars. Only downfall is the cradle does get hot after being plugged in for a period of time.
