Théo Wejieme (New Caledonia, Dumbéa)
I live in a mountainous area of New Caledonia. Because of my location, the signal in the house was very marginal. A lot of time I experienced Mobilis poor coverage or even could not get a signal at all. I researched signal repeaters that are compatible with my smartphone. The NS-450 was among the models that was reported to work with my smartphone on the Mobilis network. This model fully meets my requirements to handle Mobilis signal issues.
Some people have said that this device does not work properly but if you set it up correctly it does just fine. It is very important to orient the antenna toward the cell phone tower. I know that some people point their antenna straight up into the sky, but this is absolutely not the way such antenna is designed to work. The point is that this kind of antenna is directional. Besides make sure the outdoor antenna is installed in a clear area away from metal roofs and other objects because they can have negative effects. Moreover, if you live in a place that does not have a signal at all then this device will not help you. You simply can't get something from nothing.
I highly recommend this network signal booster. Works as described and now I can use my smartphone everywhere in the house! I check the signal at various times, it is 4-5 bars most of the time. This unit works pretty well with GSM. No more Mobilis signal problems.
