Alain Codevelle (France, Germaine)
My old house with stone walls makes 200m2. The mobile signal outside the house is 2 bars but inside signal was very random. With SFR network, we had poor coverage in 3G so I wanted an equipment supporting 3G and 4G which would work for voice and data at once.
On the advice of Marina (support manager) in live Chat, I purchased a signal booster Nikrans LCD400-GSM + 4G. Her replies by email are always quick and accurate.
I received the package in a few days, the installation was very simple although the notice is in English. I installed the outdoor antenna on the roof top and directed it to the nearest base station of SFR provider; the indoor antenna - on the ceiling in the biggest room of the house, and the booster itself was fixed on the wall. Please see attached photos.
The expected result is reached ! Now I have 5 signal bars inside my house thanks to GSM + 4G repeater from MyAmplifiers.
